I have a network of Modbus RTU master connected to daisy chain RTU slaves. I can't access nor modify the master controller. I need to connect a TCP controller to this network, just to read the registers of these slaves, without writing any values.
I'm currently using MGate MB3270 from MOXA; it's configured as Serial redirector. But the problem is that when I connect the TCP controller. I get unstable communication, it's drop continuously. Even when I replaced the TCP controller with Modbus poll, I receive Data error continuously.
When the TCP port is not connected, the communication is run smoothly between the master and the slaves.
Any advice?
