Safety guidelines

Instructions in this manual refer to Pixsys products as programmable logic controllers (PLCs) and

operating/monitoring devices (industrial PCs, HMI), from now on simply described as “device”,

“devices”. They have been designed, developed and manufactured for conventional use in industrial

environments. They were not designed, developed and manufactured for any use involving serious

risks or hazards that could lead to death, injury, serious physical damage or loss of any kind without

the implementation of exceptionally stringent safety precautions. In particular, such risks and hazards

include the use of these devices to monitor nuclear reactions in nuclear power plants, their use in

flight control or flight safety systems as well as in the control of mass transportation systems, medical

life support systems or weapons systems.

1.1 Policies and procedures
Electronic devices are never completely failsafe. If the programmable control system, operating/ monitoring device or power supply fails, the user is responsible for ensuring that other connected devices, e.g. motors, are brought to a secure state. When using programmable logic controllers or operating/monitoring devices as control systems together with a soft PLC, safety precautions relevant to industrial control systems must be observed in accordance with applicable national and international regulations. The same applies for all other devices connected to the system, such as drives. All tasks such as the installation, commissioning and servicing of devices are only permitted to be carried out by qualified personnel. Qualified personnel are those familiar with the transport, mounting, installation, commissioning and operation of devices who also have the appropriate qualifications (e.g. IEC 60364). National accident prevention regulations must be observed. The safety notices, information on connection conditions (type plate and documentation) and limit values specified in the technical data are to be read carefully before installation and commissioning and must always be observed.

1.2 Installation guidelines
· These devices are not ready for use upon delivery and must be installed and wired according to the specifications in this documentation in order for the EMC limit values to apply.
· Instal. must be performed according to this documentation using suitable equipment and tools. · Devices are only permitted to be installed by qualified personnel without voltage applied. Before
installation, voltage to the control cabinet must be switched off and prevented from being switched on again. · General safety guidelines and national accident prevention regulations must be observed. · Electrical installation must be carried out in accordance with applicable guidelines (e.g. line cross sections, fuses, protective ground connections).

1.3 Viruses and dangerous programs
This system is subject to potential risk each time data is exchanged or software is installed from a data medium (e.g. diskette, CD-ROM, USB flash drive, etc.), a network connection or the Internet. The user is responsible for assessing these dangers, implementing preventive measures such as virus protection programs, firewalls, etc. and making sure that software is only obtained from trusted sources.

1.4 Organization of safety notices
Safety notices in this manual are organized as follows:

Safety notice Description

6 – KTD710/820 – User manual

Spacing for air circulation and ventilation

In order to guarantee sufficient air circulation, allow 5cm of empty space above, below, to the side

and behind the device. No other ventilation system is required. The HMI device is self-ventilated and

approved for inclined mounting at angles up to ±35° in stationary cabinets.

Information! If additional space is needed to operate or maintain the device, this must be taken into consideration during installation. Caution! The spacing specifications for air circulation are based on the worst-case scenario for operation at the maximum specified ambient temperature. The maximum specified ambient temperature must not be exceeded! Caution! An inclined installation reduces the convection by the HMI device and therefore the maximum permissible ambient temperature for operation.

2.1 Environmental policy/WEEE
Do not dispose electric tools together with household waste material. According to European Directive 2012/19/EU on waste electrical and electronic equipment and its implementation in accordance with national law, electric tools that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility.

Connection among operator panel TD710/TD820, controllers DRR460 and I/O MCM260X modules relies on RS485 serial communication ModbusRTU protocol. The connection required is therefore of “parallel-in/out type”, that is each wire of the serial starts from terminal M1 of panel and “enters” first device. Then it “exits” to next device and so on up to the last. In particular zone controllers must be connected first and I/O modules last. Zone controllers do not have the C signal of Modbus RTU communication, so this must be connected only to I/O modules.

The position of the dip-switches for setting communication speed remains unchanged compared to other modules, therefore: DIP 1 and 4 to OFF, DIP 2 and 3 to ON.

10.c Configuration of MCM260X-4AD I/O modules for Modbus communication
The MCM260X-4AD I/O module must be configured with baud rate 19200Baud and as node number 11 for correct communication in Modbus RTU with operator panel. If the second I/O module is used, node number 12 must be associated with the latter. In the last node of the network, the line termination resistor must also always be enabled, to ensure correct Modbus signal and avoid communication errors. This configuration procedure can be performed via terminal (display and keys) or via MyPixsys App.

11 Access to system through ethernet port
Operator panel TD710/820has one ethernet port which enables the user those options: – to copy, via FTP, report files of the last 10 cycles performed – to access, through VNCviewer App from an internet browser, the user interface for system remote
control from a computer connected to the same local network (company) as the panel.

11.a Connection via FTP to operator panel If operator panel is correctly configured in the company network on which it is located (13.6 Remote Access), it is possible to acess the internal memory to export report files of the last 10 cycles performed. The cycle export function is also available simply by using a USB pen connected to the panel. To access panel memory, open a random folder of the computer in use and, in the address bar at the top, type: FTP:\192.168.0.100NandFlashRecords where “192.168.0.100” is the IP address assigned to the panel (13.6 Remote Access).
NB: any changes and/or deletion of files other than those in the “Records” folder may permanently compromise product’s functionality, the user assumes full responsibility in accessing the panel’s memory.

11.b Access to operator panel’s user interface in LAN network If operator panel is correctly configured in the company network on which it is located (13.6 Remote Access) it is possible to acess the system user interface from a computer connected to the same local network (company) as the panel.
16 – KTD710/820 – User manual

Access can be performed using VNC remote desktop software (VNCviewer recommended, available by searching online “VNCviewer”). Once the software has been installed and started, simply enter the IP address of the panel you want to access in the address bar (default 192.168.0.100). Now you use the interface as if you were in front of the “physical” touch screen. With this access mode, if you switch from one screen to another from the VNC of your computer, the real graphic interface will also consequently change screen. Another access metohd is using the HTML5 WebServer integrated into the panel. By opening any internet browser installed on your computer, entering the IP address of the panel and adding “:8080” at the end, you will access the graphical interface as a “web” server. On the one hand, with this access mode, graphic interface displayed on your computer is completely separated from the real graphic interface displayed on the touchscreen. It will be possible to view one screen while the user in front of the panel will be viewing another. On the other hand, this mode is slower than the access mode with VNC and also some graphic animations will not be displayed.
11.c Remote access to the operator panel’s user interface Operator panel is equipped with a remote connection software system that allows to acces the user interface as if he was in the same company LAN. As for the remote access mode, please consult the specific manual of the “Pixsys Portal” service. Once the VPN connection has been established through the “Pixsys Portal” service, acess to the panel can be performed exactly as described in the previous parameter.
12 Software
At a general interface level, everything on a gray background is “ready only”, that is the client can only view its status and interact by pressing the touch. The icons on a black background are “active”: the user can press them to activate the corresponding function. For example, the temperature displayed will always be on a gray backgroud (they are in fact read by the probes in the oven), while the START/ STOP buttons may become black/gray depending on the cycle’s current state (the user can interact with them).
12.1 Main synoptic
This is the main screen of the program: it is possible to view the acquired processes and their setpoints, the cycle status and any enabled auxiliaries/ alarms
The lower bar allows to access the following functions:
Allow access to the system settings (13 Table of system configurations)

Open the alarm page (15 ALARMS)

Allow access to the Synoptic settings (13 Table of system configurations)

The upper area allows access to following functions:

Alarm area: the top leftmost area of the main screen displays any alarms that are currently active. System time area: the top rightmost area of the main screen displays the current system date and time (editable from screen 13.2 CYCLE SETTINGS). Cycle information area: with cycle in progress, by pushing on this area it is possible to view details of cycle in progress (next image) Cycle information area: With the cycle running, pressing on this area displays the details of the current cycle (12.5 Running cycle)

18 – KTD710/820 – User manual

12.2 Pause a cycle
With cycle in progress, by pressing “PAUSE”, or by keeping active an input of MCM260X I/O module configured as “Pause”, it is possible to pause a cycle (indicated status will be “PAUSE”).
In this state, the cycle stops advancing in the current step (the time of the current step stops, while the total cycle time continues to advance) and, using the command bar that automatically appears on the main screen, it is possible to advance/rewind the step time by 1 or 10 minutes at a time or to move to the next/previous step.
12.3 Manual control of the kiln
With cycle in stop, by pressing “HAND”, the programmer switches to “simple controller” mode: regulation will no longer follow the cycle but it will be possible to manually set active setpoints. In this state, the setpoint value is set by pressing the area above its value and it is possible to activate/ deactivate any relay outputs if configured as “Step Auxiliary”. (the icons of the setpoint and outputs are in fact black, that is, they can be activated by the user).
12.4 Start a new cycle
After having created at least one cycle, it is possible to start it from the main screen by pressing the “START” button. At this point a window will appear allowing you to choose to start the cycle immediately or, if the options are enabled, according to the set schedule or delay. It is also possible to add notes to the cycle, which will then be visible in the .CSV report file.
The drop-down menu allows you to select the cycle you wish to start. If at least one of the functions between “Enable delayed start” or “Enable timed start” is enabled, the “Configure start times/timetable” button will be visible, allowing you to: – Start the cycle according to the calendar schedule (for more info see parameter “Enable start at
time” in section 13.2 CYCLE SETTINGS). – Start the cycle after a preset waiting time (in minutes) (for more information see parameter “Enable
delayed start” in section 13.2 CYCLE SETTINGS). Furthermore, if the “repeat cycle” or “skip cycle” function is enabled, the “REPEAT / SKIP” button will be visible and will open a second window:
User manual – KTD710/820 – 19

With the first check you can decide at the end of the cycle, whether this must be repeated and for how many times (“repeat cycle” function). With the second check you can decide to run a specific cycle when the first one is finished (“jump to cycle” function).
12.5 Running cycle
When a cycle is running, the top left section of the main page shows · the name of the cycle currently running (eventually its repetitions and/or the next cycle) · the type of step in progress (rising, holding, cooling, recovery, etc.) · the progression info and total duration of the cycle and step in progress · by pressing the area with the black background, you can see the details of the steps programmed
With the cycle running, the cycle editing page is in display-only mode (no changes can be made). If you press the padlock icon, and confirm the request in the window that appears, it becomes possible to change the temperature values and step times of the current cycle.
Warning! By saving changes on exiting the page, new values are immediately applied to the cycle in progress. Pay attention!
The SPV setpoint section becomes with a black background, so pressing on that area a detail popup appears:
The window shows for each active oven zone: · its process and its setpoint (if it is a
control zone) · the output percentage · the theoretical and actual
temperature gradient · if the EnergyMeter is active, the
currents and voltages of the monitored phases.
20 – KTD710/820 – User manual

12.6 End of cycle
At the end of the cycle, a window will appear with the data of the completed cycle:
The window shows: – Start and end time of the cycle – Estimated (theoretical) and actual duration of the cycle just executed – Consumption in kWh (if EnergyMeter is enabled, 13.7.4 ENERGY MONITORING).
13 Table of system configurations
Press the icon next to it to access the system settings
System configuration implies parameterizing the following aspects of the kiln. – Configuration of active processes and related regulation zones – Cycle configuration (regulation mode, cycle performance in case of waiting for the end of the step,

NB: The pages for creating/editing recipes “MODIFY CYCLES” and saving/loading cycles “IMPORT CYCLES” are normally available for access by the user without entering any password, while the other buttons are only available after pressing the button with the gears and entering the installer password (default “1234”) in the window that appears.
After logging in as installer, from the “ADVANCED” page it is possible to change the access password to one of your choice (maximum 4 digits), and it is also possible to set a “user” password for access to the cycle creation/editing and import/export pages in order to protect those sections as well.
With “Login” the inserted password is confirmed and the other advanced configuration buttons are unlocked. Access as an installer lasts for 30 minutes after which you will need to re-enter the password. This allows the installer to carry out all system configuration and necessary tests without having to enter password every time. It is possible to exit installer mode to return to user mode by waiting 30 minutes or opening the password entry window again and pushing the “Logout” button. Otherwise, switch the terminal off and on again.

13.2 CYCLE SETTINGS
This screen allows the general configuration of the programmer during cycle execution.
It consists of 4 pages.
The first page allows programmer general configuration during cycle execution.
· Starting setpoint type Configure starting cycle setpoint mode:
– Disable: Starting setpoint cycle disabled. The cycle will always start with setpoint equal to 0°C. – Fixed at 25°C: starting setpoint fixed at a “25°C”. The cycle will always start with setpoint equal to
25°C. – Editable in recipe: Starting setpoint editable from recipe window. Il is possible to set a different
initial setpoint for each cycle. · Waiting time step end If at the end of a step the process is delayed, that is, if it differs from setpoint by a value higher than that set in the “Max gap step end” parameter, the following step starts only after the time programmed in this parameter, or when this difference is within the margin of the maximum programmed deviation “0” = Waiting step end excluded. Limits 1..999 minuti. Default: 60 minutes. · Max gap step end Sets the max deviation for activation of step end wait in case the zone is delayed with respect to the final setpoint set for step in progress. If during waiting step end, the “Setpoint – Process1 difference” becomes lower than this parameter, the cycle still passes to the next step without having waited for time end programmed in the “Waiting time step end” parameter. Limits 0.0..99.9 tenths of degree. Default: 10.0 (10°C). · Recovery enabled Allows to choose performance of programmer in case there is a shutdown and subsequent restart while a cycle in progress: – Disable: at restarting the programmer is set to STOP. – Fix gradient: when the operator panel is switched on again and the difference between the process
and the setpoint before switching off is greater than the set value, in the “Min gap for recovery” parameter the cycle starts again with a setpoint equal to the current process value and a ramp with gradient equal to the value set in the “Gradient value” parameter (defined in °C/hour). – Ceramic: at restarting of the controller, the cycle restarts as follows. If the gap between process and setpoint before switching off is lower than value set on parameter “min gap for recovery”, the cycle starts from the point at which it was interrupted. On the contrary, if the gap between process and setpoint before switching off is bigger than value set on parameter “Min gap for recovery”, there are two different recovery models, according to the type of step that the controller was executing: · RISING OR HOLDING STEP: at restaring the controllers scrolls the cycle backwards s to reach the
setpoint value lower or equal to the process value. From that point, the controller restarts cycle, repeating rising steps and omitting the holding steps which had alredy been completed. When
User manual – KTD710/820 – 27

the cycle reaches the point at which it had been interrupted, the recovery functions stops and the cycle continues regularly · COOLING STEP: at restarting, the controller scrolls the cycle values onwards to reach the setpoint value lower or equal to process value. From this point, the cycle continues regularly according to programmed values. In both cases, time of the cycle in progress is maintained and the cycle status becomes “RECOVERING” until step end in progress when restarted. Default Ceramic. · Min gap for recovery Sets the min deviation for activation of cycle recovery (if enabled. Default 10.0 (0°C). · Gas Mode Sets type of operation for the kiln (13.2.a GAS mode) · Enable delayed start Enables the possibility to start the cycle after a waiting time (which can be set from the cycle start window, 12.4 Start a new cycle). During the waiting period for the programmed start, the cycle status will display “WAITING TO START” and the cycle time field will display the hours and minutes until start. It is however possible to start the cycle immediately by pressing the green “START NOW!” button from the main screen. N.B.: In the event of a power failure while waiting for the cycle to start, the programmer will immediately start the cycle when it is switched on again. Default NO · Enable scheduled start Enables to start a new cycle at a precise time and date (settable from start cycle, 12.4 Start a new cycle). The cycle will start at the preset time and day. In the event of a power failure while waiting for the cycle to start, the controller will keep the schedule active. Default NO
The second page enables some special functions of cycle, selection of control quantity and reference “SPV” setpoints.
· SPV1 control source Selects the control variable for the main setpoint SPV1. This process is also the one that defines the ‘wait end step’ status and the recovery mode in the event of a system power failure. Default: Process 1 (i.e. the process related to control zone 1). · Enable repeat cycle Enables to automatically repeat the cycle when it is finished. (12.4 Start a new cycle). · Enable jump to cycle Enables to automatically run a different cycle when the previous one is finished. (12.4 Start a new cycle). · Enable aux duration Enables the possibility of choosing the activation duration of the auxiliary output set as “AUX”: during the cycle, at the beginning of the step in which the output has been selected as active, the relevant relay is activated only for the set seconds and not for the entire duration of the step. The seconds are set on the cycle creation/editing page in the column relating to the auxiliary activated as “AUX”. (12.4 Start a new cycle). · N. decimals SPV1 – N. decimals SPV1 Defines number of decimal places for reference setpoint “SPV1” and “SPV2”.

13.7.3 DEVICE DIAGNOSTICS

Here you can enter the DRR460 node

number, MCM260X I/O module or

EnergyMeter 2000.35.032 if enabled,

whose status you want to check by

pressing “Check Diagnostics” and

accessing the detail pages described

below.

Once the device to be controlled has been chosen, the page displays its status:

Using the appropriate buttons it is also possible to:

–

Restore the DRR460 controller / the MCM260X-4AD module to factory conditions

–

Download the device manual on the USB key possibly connected to the panel.

Finally, the firmware version of the device is displayed.

In case of diagnostics of a DRR460 controller, the window also shows configuration of dip-switches for correct setting of baud rate and number of slaves. It is also possible to verify any anomalies by signaling the respective “Error flag”.
· Node activated Indicates that the node is active in the Modbus network. If the node has been enabled by the parameters but the indicator is not lit, check the wiring and Modbus configuration of the node, then switch the whole system off and on again. · Node missing Indicates that the node, active in the network, is not responding to Modbus requests from the operator panel. If the indicator is lit, check whether the cabling is correctly laid and stable, and whether there are sources of disturbance (e.g. contactor switching on/off) that may temporarily cause loss of communication between the operator panel and the device. In this case, try to isolate the modbus communication cables from the power cables. · Lost packets Shows the counter of lost packets (missed Modbus communications) of the node. If the counter increases continuously, carry out the checks in the previous point or possibly replace the device. If, on the other hand, the counter seldom increases by 1/2 packet or in any case has very low values (less than 10/20 per day), it could mean that at some juncture in the operation of the furnace (switching on/ off of contactors) there are disturbances which cause a temporary loss of communication. In this case, try to isolate the Modbus communication cables from the power cables.

User manual – KTD710/820 – 39

Il collegamento tra il pannello operatore TD710/TD820, i regolatori DRR460 e i moduli I/O MCM260X viene effettuato attraverso una comunicazione di tipo seriale RS485, con protocollo ModbusRTU. Il collegamento che va effettuato quindi è di tipo “in parallelo – entra/esci” cioè con ciascun filo della seriale che parte dal morsetto M1 del pannello ed “entra” nel primo dispositivo e poi “esce” al dispositivo successivo e così via fino all’ultimo. In particolare, vanno collegati prima i regolatori di zona e per ultimi i moduli I/O. I regolatori di zona non hanno il segnale C della comunicazione Modbus RTU, quindi questo va collegato solo ai moduli I/O.

La posizione dei dip-switch per l’impostazione della velocità di comunicazione invece resta invariata per tutti i moduli, quindi: DIP 1 e 2 a ON, DIP 3 e 4 a OFF.
10.c Configurazione dei moduli I/O MCM260X-4AD per la comunicazione Modbus Il modulo I/O MCM260X-4AD va configurato con baudrate 19200Baud e come numero nodo 11 per la corretta comunicazione in Modbus RTU con il pannello operatore. Nel caso di utilizzo del secondo modulo I/O, a quest’ultimo va associato il numero nodo 12. Nell’ultimo nodo della rete, va inoltre sempre abilitata la resistenza di terminazione di linea, per assicurare una maggior “pulizia” del segnale Modbus ed evitare errori di comunicazione. Questa procedura di configurazione può essere eseguita tramite il terminale (display e tasti) oppure tramite l’app MyPixsys. Di seguito viene riportata la procedura per la modifica dei parametri tramite il terminale.

per il controllo remoto del sistema da un computer collegato alla rete locale (azienda) dove è collegato anche il pannello.

11.a Connessione via FTP al pannello operatore Se il pannello operatore è correttamente configurato nella rete aziendale su cui si trova, è possibile accedere alla memoria interna per poter esportare i file di report degli ultimi 10 cicli eseguiti. La funzione di esportazione dei cicli è anche disponibile semplicemente utilizzando un penna USB collegata al pannello. Per accedere alla memoria del pannello, aprire una cartella qualsiasi del computer in uso e, nella barra degli indirizzi in alto digitare: FTP:\192.168.0.100NandFlashRecords dove “192.168.0.100” è l’indirizzo IP assegnato al pannello (13.6 Accesso remoto).
NB: Eventuali modifiche e/o eliminazione di file diversi da quelli presenti all’interno della cartella “Records” possono compromettere in maniera definitiva le funzionalità del prodotto, l’utente si assume la piena responsabilità nell’accedere alla memoria del pannello.

11.b Accesso all’interfaccia utente del pannello operatore in una rete interna Se il pannello operatore è correttamente configurato nella rete aziendale su cui si trova (13.6 Accesso remoto) è possibile accedere all’interfaccia utente del sistema da un computer collegato alla stessa rete locale (azienda) dove è collegato anche il pannello. L’acceso può essere eseguito utilizzando un software di desktop remoto VNC (consigliato VNCviewer,

reperibile cercando su Google “VNCviewer”). Una volta installato e avviato il software, è sufficiente inserire nella barra degli indirizzi proposta l’indirizzo IP del pannello a cui si vuole accedere (default 192.168.0.100). A questo punto si può agire sull’interfaccia come si fosse di fronte al touch screen “fisico”. Con questa modalità di accesso, se si passa da una schermata ad un’altra dal VNC del proprio computer, anche l’interfaccia grafica reale cambierà schermata di conseguenza. Un’altra modalità di accesso possibile è quella di sfruttare il WebServer HTML5 integrato nel pannello. Aprendo quindi un qualsiasi browser internet installato nel proprio computer ed inserendo l’indirizzo IP del pannello aggiungendo alla fine “:8080”, si accederà all’interfaccia grafica come utente “web”. Conquestamodalità di accesso, l’interfaccia grafica visualizzata nelpropriocomputer,ècompletamente separata dall’interfaccia grafica reale visualizzata sul touch screen, quindi sarà possibile visualizzare una schermata mentre l’utente davanti al pannello ne starà visualizzando un’altra. Di contro, questa modalità risulta più lenta rispetto alla modalità di accesso con VNC ed inoltre alcune animazioni grafiche non saranno visualizzate.
11.c Accesso all’interfaccia utente del pannello operatore da remoto Il pannello operatore è fornito di un sistema software di connessione remota che permette di accedere all’interfaccia utente come se ci si trovasse nella stessa rete LAN aziendale. Per la modalità di accesso remoto, si rimanda al manuale specifico del servizio “PixsysPortal”. Una volta instaurata la connessione VPN remota attraverso il servizio “PixsysPortal”, l’accesso al pannello può venir effettuato esattamente come descritto nel parametro precedente.
12 Il software
A livello generale di interfaccia, tutto ciò che è su sfondo grigio è di “sola lettura”, cioè l’utente può solo visualizzarne lo stato e non può interagire premendo il touch, mentre le icone su sfondo nero sono “attive”, perciò l’utente potrà premerle per attivarne la funzione corrispondente. Le temperature visualizzate ad esempio, saranno sempre su sfondo grigio (vengono infatti lette dalle sonde nel forno), mentre i pulsanti di START/STOP potranno diventare neri/grigi a seconda dello stato attuale del ciclo (l’utente può interagire con essi).
12.1 Sinottico principale

Questa è la schermata principale del programma: da qui è possibile visualizzare i processi attivi ed i relativi setpoint, lo stato del ciclo e degli eventuali ausiliari/allarmi abilitati.

La barra inferiore permette di accedere alle seguenti funzioni:
Permette di accedere alle impostazioni del sistema (13 Elenco delle configurazioni del sistema)

Avvia il ciclo selezionato (12.4 Avviare un ciclo)

Manuale d’uso – KTD710/820 – 57

Abilita la funzione di controllo manuale (12.3 Controllo manuale del forno)
Mette in pausa il ciclo in esecuzione e permette di avanzare/indietreggiare di 1/10 minuti o di un intero step (12.2 Mettere in pausa un ciclo)
Apre la pagina degli allarmi (15 GLI ALLARMI)
Permette di accedere al sinottico di visualizzazione del grafico dell’ultimo ciclo eseguito e alla gestione dei file di registrazione. (14 IL GRAFICO)
La zona superiore permette di accedere alle seguenti funzioni: Area allarmi: nell’area più in alto a sinistra della schermata principale è possibile visualizzare gli allarmi eventualmente attivi in quel momento. Area orario di sistema: nell’area più in alto a destra della schermata principale viene visualizzata la data e l’ora attuale del sistema (modificabile dalla schermata 13.8 L’OROLOGIO). Area informazioni ciclo: con il ciclo in esecuzione, premendo su quest’area è possibile visualizzare i dettagli del ciclo in corso (vedi 12.5 Ciclo in esecuzione).
12.2 Mettere in pausa un ciclo
Con ciclo in esecuzione, premendo il pulsante “PAUSA”, oppure attivando un ingresso del modulo I/O MCM260X configurato come “Pausa”, è possibile mettere in pausa il ciclo (lo stato indicato sarà “PAUSA”).
In questo stato, il ciclo smette di avanzare nello step in corso (il tempo dello step in corso si ferma, mentre il tempo totale del ciclo continua ad avanzare) e, utilizzando la barra dei comandi che appare automaticamente nel sinottico principale, è possibile far avanzare/retrocedere il tempo dello step di 1 o 10 minuti alla volta oppure passare allo step successivo/precedente.
