– Serial Port configuration page

Modbus Gateway settings

The serial server will perform conversion from Modbus/TCP to Modbus/RTU, allowing polling by

a Modbus/TCP master. The Modbus IPSerial Gateway carries out translation between Modbus/TCP and
Modbus/RTU. This means that Modbus serial slaves can be directly attached to the unit's serial ports
without any external protocol converters.

Click

Serial Port

Tab to open the Modbus Gateway configuration screen. Choose Modbus Gateway

settings to configure Modbus. At the Figure

Description

TCP accept port

This field determines the TCP port number that the serial server will listen for
connections on. The value entered should be a valid TCP port number. The
default Modbus/TCP port number is 502.

Connection timeout

When this field is set to a value greater than 0, the serial server will close
