Introduction

Industrial Interface

DI/DO

Digital I/O interface may be used as switch of high level for logical 1 and low level for logical 0.

DI

Digital Input.

When input event High level/Low level/Counter occur what should be done.

DO

Digital Output.

Serial

RS485

Support half-duplex serial communication distance up to 120m.

RS232

Support full-duplex serial communication distance up to 20m.

Settings

The following settings are common to all modes of the serial port.

Setting	Description	Default
Enable	Enable serial port	disable
Serial Type	Serial port type (Predefined)	-
Baud Rate	Serial port baudrate	9600
Data Bits	Serial port data bits	8
Stop Bits	Serial port stop bits	1
Parity	Serial port parity bit	None
Software Flow Control	Serial port flow control	disable
Serial Mode	Serial port work mode	transparent

Serial support three work modes:

• DTU Mode
• Modbus Slave
• Modbus Master

DTU Mode

Monitor the serial status and sync to remote server.

• Transparent

  • TCP client
  • UDP client

• Modbus

• TCP Server

• UDP Server

• MQTT

Modbus Slave

Monitor the DI status and change the DO status.

Modbus TCP

Define DI/DO ports and monitor the DI status and change the DO status via Modbus TCP.

Modbus RTU

Define DI/DO ports and monitor the DI status and change the DO status via Modbus RTU.

Modbus RTU Over TCP

Define DI/DO ports and monitor the DI status and change the DO status via Modbus RTU Over TCP.

Modbus Master

Monitor the Modbus Slave and react accordingly.
