Hello friends! There is a problem with the operation of the MASTER modbas on the 224 controller. What I want: configure your controller to work as a master modbass and read data from modbas temperature sensors. I wrote a program (it is in the application). I try to check the work through the USB-modbas converter and the Modbas Slave program. I want to send VW0 = 5 from PLC to the computer. A screen of what comes attached .... When you change the controller to modbas slave, everything works! through the Modbass Poll program I turn on Q 0.1 ... Q 0.5 without problems! So the cable is normal, the usb modbas converter too! Why does the controller send such rubbish? It doesn't look like a modbass message at all ... it doesn't look like anything
