This document describes how to use EasyView touchscreen to operate and read/write the registers data or status of Xinje FC series PLC devices, and communicate using ModBus protocol.
The document describes the required hardware wiring between an EasyView touch screen and an FC series PLC, including the use of a Mini‑Din 8 connector and the short‑circuit of pins 2 and 8 when using the COM1 port. It also details the Modbus communication settings such as baud rate, data bits, parity and stop bits.
Configuration steps are provided using the FCP30 programming software: set the PLC communication parameters, program registers FW183 and FW184, power‑cycle the PLC, and then create EasyView screens that read and write PLC registers. An example shows how to control a PLC relay (M0) from EasyView and how to map EasyView objects to PLC addresses. This manual is written in Chinese.
| Communication protocol | Modbus RTU |
|---|---|
| COM port used | COM2 |
| Baud rate | 9600 |
| PLC station number | 1 |
| Register FW183 value | 0105 |
| Register FW184 value | 0008 |
The manual specifies using the PLC’s COM2 port for communication with EasyView.
The manual provides a mapping table, for example device type 0x address 1 maps to MO, 0x address 2 maps to MI, etc.
