Hi!
I have one modbus TCP unit. I've tested communication with this unit via "AVReporter Modbus Communication Tester" . All ok, all working.
But in Zenon 7.11 EE I've used MODRTU32 driver and can't read any variable (function 3, Holidng register)
I checked, that in Modbus TCP tester i use Slave Address=1(when i set it to 255(0xFF), my unit stop answering). But in MODRTU32 i can't set or check, what slave adress is have used.
Can i set slave addr in modbus tcp driver?
