COM3 AC800M Modbus
I Have PM864A 5.1 (no backup), I want to connect it with modbus Master RTU to TotalFlow (Slave) with COM3.
I used MbConnect and MbRead.
The Com3 Tx led flashes when polling and the the TotalFlow also receive a polls.
The Com3 Rx led flashes when receiving but nothing on control builder all times -4929 (timeout).
I tried with modbus poll and modbus slave with the same result.
What wrong on my program?
