It is PLC based product with software tools allowing users to design GUI. Different communication protocols offers various connectivity opportunities. Aluminium frame with resistive touch screen offers an intuitive, clear and flexible interface between the user and the building. LPC-3.GOT.002 is equipped with Ethernet connection and can be used as a Modbus TCP/IP Master and/or Slave device or BACnet IP (B-ASC). USB port is used for local programming and debugging. Over TCP/IP, programming and debugging is possible via LAN (inside building) or even via WAN network (remotely over internet). LPC-3.GOT.002 is powered from external DC power supply. LPC-3.GOT.002 includes two galvanic isolated CAN bus for CANopen protocol and non-isolated RS-485 bus for Modbus RTU master protocol, used e.g. for local or remote connection to other LPC PLCs. It also has Smarteh bus port for connection with Smarteh LPC-2 slave devices. Integrated ''Setting Storage FLASH'', "RTC" and "NV RAM", does not need the battery for it is functioning. There is also a built-in buzzer which can be controlled through PLC program. Smarteh IDE (Integrated Development Environment) software tool is used with all the PLCs from the LPC family and it supports all five standard PLC programmable languages (FBD, LD, SFC, ST, IL). It also supports "off line'', ''on line'' debugging and local/remote program transferring. Distributed processing is supported which makes it possible to handle fast operations. GUI design tool supports large set of dynamic controls from buttons to indicators and enables connectivity between PLC programs and user interface. LPC-3.GOT.002 is an innovative and an attractive solution for a competitive price. 2 Longo programmable controller LPC-3.GOT.002 3 FEATURES Figure 1: LPC-3.GOT.002 Table 1: Features Aluminium frame with 7" LCD display and resistive touch screen - landscape or portrait orientation Graphical interface is freely designed by the user with GUI editor in SmartehIDE Ethernet connectivity with Modbus TCP/IP Slave (server) and/or Master (client) functionality, BACnet IP (B-ASC), web server and SSL Modbus RTU Master or Slave Smarteh bus USB port for debugging and application transfer Remote access and application transfer 2 galvanic isolated (2500 V DC) CAN port - one for master, one for slave RTC and 512 kB NV RAM with super capacitor for needed energy storage Micro SD Card slot Built-in buzzer controlled from PLC program Display brightness level controlled from PLC program Disconnectable spring type connectors Status LEDs Flush mount Quality design 3 Longo programmable controller LPC-3.GOT.002 4 INSTALLATION 4.1 Block diagram Figure 2: LPC-3.GOT block diagram1 1 Coloured areas represents different voltage domains - galvanic isolated areas.

For analog (Input and Holding registers) this means 123 values, while for digital (Statuses and Coils) this means 1968 values. When higher quantity of data is required, LPC-3.GOT.002 can execute up to 32 same or different supported commands simultaneous. Physical layer: RS-485 Supported baud rates: 9600, 19200, 38400, 57600 and 115200bps Parity: None, Odd, Even. Stop bit: 1 Modbus RTU slave unit Modbus TCP slave has 1023 addresses in each memory section: Coils: Discrete inputs: Input register: Holding registers: 00000 to 01023 10000 to 11023 30000 to 31023 40000 to 41023 Highest scan rate is 100 ms. Smarteh RS485 bus for connectivity with LPC-2 system Port COM1 is used for communication with LPC-2 slave modules. All communication settings are configured in SmartehIDE software program. BACnet IP unit When configured for BACnet IP (B-ACS), following commands are supported: Data Sharing ReadProperty-B (DS-RP-B) WriteProperty-B (DS-WP-B) Device and Network Management Dynamic Device Binding-B (DM-DDB-B) Dynamic Object Binding-B (DM-DOB-B) Device Communication Control-B (DM-DCC-B) Time Synchronization-B (DM-TS-B) UTCTimeSynchronization-B (DM-UTC-B) For more information, please contact producer. CANopen unit CANopen unit consists of Master and Slave communication ports. They are independent, thus can be connected to two different CAN network at the same time. The ports can operate at baud rates 50 kbps, 125 kbps or 250 kbps. It follows the internationally standardized (EN 50325-4) CAN-based higher-layer protocol for 13 Longo programmable controller LPC-3.GOT.002 embedded control systems. Advised rules and concepts by this standard must be followed to fulfil the conditions and so achieving normal operation and results. The structure of the network as cable type and lengths, baud rates, number of the nodes and termination must be taken into account within the recommendations and requirements, when designing the network. The bus network can consist of at least one Master and at list one Slave node by the standard, but it is advised that with increased number of nodes, the Master node fastest interval is extended. Below are two examples: Example 1: network with 1 master and 9 slaves, every slave have defined 32 (4x8) byte of data and baud rate 125 Kbps. Fastest Cycle time for this configuration is 50 ms. Example 2: network with 1 master and 4 slaves, every slave have defined 4 byte of data and baud rate 250 Kbps. Fastest Cycle time for this configuration is 5 ms. 5 ms is the fastest recommended cycle time. It is recommended to power-up all the nodes on the same network at the same time, if some or all nodes had been reprogrammed (to reinitialize the communication properly). Figure 7: CAN Master and Slave wiring diagram example RUN/STOP Switch Run: Status RUN status LED "on" indicate that the user graphical application is up and user program is running. Stop: When the switch is turn to STOP state, the RUN status LED is "off" and application is stopped. PLC task cycle time Main PLC task interval (under Project tab -> Resource Tasks Interval) time is not recommended to be set lower than 50 ms. 14 Longo programmable controller LPC-3.GOT.002 7.2 GUI design and programming Figure 8: LPC Manager interface example6 Figure 9: Inkscape open source tool7 NOTE: Recommended minimum size of the touch object is 10 x 10 mm. 6 Configuration of the PLC is done using Smarteh IDE software tool.
