MGate MB3000 User’s Manual Configuring the Modbus Gateway

9-10

Configure Serial Port for RTU or ASCII, Master or Slave

The Mode tab is where each serial port’s operation mode is configured. The operation mode

determines whether the device(s) that are connected to the serial port will operate as a master or a

slave, and whether the Modbus RTU or Modbus ASCII protocol will be used. There are four

operation modes as follows:

Mode

Description

RTU Slave

Modbus RTU slave(s) will be connected to the serial port.

RTU Master

A Modbus RTU master will be connected to the serial port.

ASCII Slave

Modbus ASCII slave(s) will be connected to the serial port.

ASCII Master

A Modbus ASCII master will be connected to the serial port.

 For entry-level models (MB3180, MB3280, and MB3480), Modbus TCP masters will control

Modbus RTU/ASCII slaves, and Modbus RTU/ASCII masters will control Modbus TCP slaves.

 For advanced models (MB3170, MB3270), both Modbus TCP and Modbus RTU/ASCII masters

can control Modbus TCP and Modbus RTU/ASCII slaves.

Use the radio buttons to select the desired operation mode for each serial port on the Modbus

gateway. Select the ProCOM Enable check box located in the center of the page to enable ProCOM.

For detailed information, refer to the ProCOM function description in this manual.
