I'm trying to make a Siemens 1200 PLC talk to an Allen Bradley Micrologix 1400 PLC through Modbus TCP. The Siemens is the "Server."
The Siemens is able to successfully send data TO the Allen Bradley, but nothing ever comes back. All of the data transactions take 3 seconds, and end with a "port busy" error code.
Does this sound familiar to anybody? TIA.
