TCP server

[acxysty]

We have an application that need to manage the Mobus TCP server : sometimes it has to be ready to be open and sometimes it has to be closed without going out of the runing program.
How can we manage that ?

Do you mean the PLC program can selectively enable/disable its own Modbus/TCP server? There isn't such an option on these PLCs at the moment.

To prevent access to the Modbus/TCP server you can enable the trusted IP address and put in an invalid IP address there, which will make the Modbus/TCP server become inaccessible.

Thank you for your answer.
