ELECTRICAL CONNECTIONS 4.1 WIRING BEST PRACTICES The following information describes the wiring guidelines and best practices which should be observed when using the equipment described in this manual. DANGER RISK OF ELECTRIC SHOCK, EXPLOSION OR ELECTRIC ARC · Only use electrically insulated measuring devices and equipment. · Do not install the equipment while the power supply is connected. · Switch off all equipment, including connected devices, before installing or uninstalling the device. · Always use a correctly calibrated voltmeter to check the system is switched off. · Do not touch the unshielded components or the terminals while they are live. · Do not open, disassemble, repair or modify the product. · Do not expose the equipment to liquids or chemicals. · Before applying voltage to the equipment: · Make sure all protective elements, such as covers, hatches and grilles, are fitted and/or closed. · Check all wiring connections. 4.1.1 Wiring guidelines When wiring the controllers, observe the following instructions: · The I/O and communication wiring must be kept separate from the power supply wiring. These two types of wiring must be routed in separate ducts. · Make sure the operating environment and conditions fall within the specified values. · Use wires with the correct diameter, suited to the voltage and current requirements. · Use copper conductors (compulsory). · Use shielded twisted pair cables for analogue/digital I/O connections. Use correctly earthed shielded cables for all analogue inputs or outputs and for communication connections. If shielded cables are not used for these connections, electromagnetic interference could cause the signal to deteriorate. Deteriorated signals can lead to unpredictable operation of the controller or modules and connected equipment.

MODBUS TCP FUNCTIONS AND RESOURCES 9.1 INTRODUCTION The Modbus TCP is a variant of Modbus and is based on the TCP that allows sending messages over an Intranet and the Internet. The Modbus TCP uses binary data encoding and the TCP detection mechanism for transmission errors. It also uses the Master - Slave paradigm, in the Client - Server variant between devices connected to a TCP Ethernet network. Four types of messages are used in this type of communication. Request Indication Client Modbus Server Modbus Confirmation Response Fig. 35. Diagram showing message exchange in a Modbus TCP communication The Modbus TCP message exchange service is used to exchange data in real time between two application devices, between application devices and other devices, between HMI (Human Machine Interface) or SCADA applications and devices, and between PCs and application devices that provide online services. Only the client device identified as the master can initiate a transaction, building the message ADU, whose function code tells the server what action to take. ADU MBAP Header Function code Data PDU Fig. 36. Framing of a message using the Modbus TCP For further information relating to the Modbus protocol, visit the official Modbus website: www.modbus.org. 9.2 MANAGING MODBUS CONNECTIONS OVER A TCP NETWORK EV3 Web supports up to 5 concurrent Modbus client connections. If a new connection request is received and the number of connections is already at the limit, the connection is rejected. 9.3 MODBUS MESSAGE STRUCTURE The Modbus protocol uses a 16-bit word. The Modbus message starts with a header. A Modbus message uses a Modbus function code as the first byte. A description of the structure of a modbus message header is given below. Uniqueidentifier Type of protocol Command length Unit ID Modbus message 2 bytes 2 bytes 2 bytes 1 byte N-bytes Field associating a request with a response The Modbus field value is always 0 This field is used to The field value is the size of the rest of the message identify a remote server located on a non-TCP network (for serial connection) The first byte is the Modbus function code 1143W01E4.01 · EV3 Web | 27 | 07/2023 9.4 MODBUS FUNCTIONS AND REGISTERS The Modbus registers for the device are organised around the four types of basic data reference indicated above, and this type of data is further identified by the first number of the address. 9.4.1 Available Modbus commands and data areas The commands implemented are as follows: Command 03 (hex 0x03) 06 (hex 0x06) 16 (hex 0x10) Description Resource reading command Resource writing command Writing command for one or more registers 9.5 ADDRESS CONFIGURATION Node address 0 is used exclusively for broadcast messages, recognized by all servers. To a broadcast message, the Server devices do not respond. To work with Modbus TCP the BLE parameter must be 1. In this case the LA, Lb and BLE parameters must not be modified. The address of a device within a Modbus message is set by the LA parameter. Address 0 is only used for broadcast messages, recognised by all slaves. Slave devices do not respond to a broadcast message. Unit address: this is the address of the node that allows communicating with the connected instrument or with other slaves. Holding register number: modbus addresses of each instrument. Modbus TCP default port: 502. 9.6 OPERATION 9.6.1 Stand-alone operation To communicate solely with EV3 200 Web, set the Destination ID of the modbus message to 247 (value set by the BLE = 1 parameter). NOTICE NO COMMUNICATION Do not change the default value of the BLE parameter. 9.6.2 Cloud + Modbus TCP In this operating mode it is possible to use up to 10 devices (1 EV3 Web + 9 compatible EPocA devices) Client 1 2 3 9 (SCADA) Ethernet RS-485 Setup · Modbus TCP = 1; · Operation Mode = Cloud.

There are 2 tables: · Modbus parameter table, which contains all the configuration parameters for the device and the corresponding addresses · Modbus resource table, which contains all the status (I/O) and alarm resources in the device memory. Description of columns in the Table of addresses · Par.: List of configurable device parameters; · Description: Indicates parameter operation and any possible selections; · UM: Measurement unit relating to the parameter; · Range: Describes the interval of values that the parameter can assume. This can be correlated with other instrument parameters (indicated with the parameter code). NOTE: If the actual value is outside the permitted limits for that parameter (for example, because other parameters defining the aforementioned limits have been altered), the value of the violated limit is displayed instead of the actual value; · Val. Adr.: Indicates the address of the Modbus register containing the resource you want to access; · Filter value: bit position of the data to be considered in the holding register. This information is always provided when the register contains more than one piece of information and it is necessary to distinguish which bits actually represent the data (the useful size of the data indicated in the DATA SIZE column should also be taken into account); NOTE: Some holding registers contain two separate fields: one contained in the MSB (most significant byte) and the other in the LESS. · R/W: Indicates the option of reading or writing the resource: · R: The resource is read-only; · W: The resource is write-only; · R/W: The resource can be both read and written. · CPL: When the fields indicates Y, the value read by the register needs to be converted because the value represents a number with a sign. In the other cases the value is always positive or zero. · DATA SIZE: Indicates the size in data bits: · WORD = 16 bits · Byte = 8 bits · The "n" bit = 0...15 bit depending on the value of "n". 1143W01E4.01 · EV3 Web | 29 | 07/2023 9.8 EV3 WEB MODBUS ADDRESSES 9.8.1 Table of Modbus Parameters Par.
