Question

Is it possible to use TRB140 as a gateway between PLC1 in TCP network as modbus tsp client, and remote PLC2 (with TRB140) as modbus tsp server? If yes, how to do it?

Answer 1

Hello,

Thank you for contacting Teltonika Networks VIP Helpdesk.

TRB140 has both features of Modbus TCP slave(client) and Modbus TCP Master(server).

A Modbus TCP Slave listens for connections from a TCP master (client) and sends out a response or sets some system related parameter in accordance with the given query. This provides the user with the possibility to set or get system parameters.

A Modbus Master device can request data from Modbus slaves. The Modbus TCP Master section is used to configure Modbus TCP slaves.

Check the following link on how it can be configured https://wiki.teltonika-networks.com/view/TRB140_Modbus

Kind regards,

Shadrack.
