Question

After updating serveral RUT 230 to FW 01.12 the behavier of the internal modbus server has changed:

Modbus requests will still be answerd, but TCP connection is terminated after by the RUT.

I do not know any other modbus Server akting like that.

Answer 1

Hello,

This was added as a secure measure to avoid one master from taking over connection. With other firmware release we will add check box, which will allow enable to persist Modbus TCP connection between master and slave.
