I have a modem I have programmed to translate modbustcp to rtu and I use the simulator in our test network.
Rtu polling is read correctly in the simulator (it receives the message from com4 perfectly) but it does not respond to the polling.
Comm log says that poll is received for 0 for 10, but nothing is written back to com4 - is this how the simulator works, that it does not respond to rtu messages?
Or is the fault in my program (it is rudimentary application that only sends the data to serial and begins receiving what
ever is written to the com, but it does not receive anything)...
