Hello all,
We are working on a traceability system that includes one machine with an omrom cpu with modbus tcp. The manufacturer of the machine send us the protocol of communications and everything works fine until there are any communication problems.
Once these problems arise it is imposible to restablish the tcp communications between the PLC and the supervisor PC. The only way is shutting down the machine and power it on again (restart). It seems that the system only allows one tcp connection and it hangs up for some reason.
Is there away to reset modbus communications without powering down the machine?
Thanks a lot.
