I have Micro850 with module 2080-Serialisol.
It is needed to read 5 registers from a device via Modbus RTU.
The device is Ok, I can read the data via Modbus Pool.
But when I try to read from PLC:
1. If Trigger type is 0, then there is error 33 in MSG_Modbus.
Result - no data is read from device, LocAddr=0
2. If Trigger type is 1, then there is no error in MSG_Modbus.
Result - no data is read from device, every word in LocAddr = 0
I changed a polarity of connection to the module, put the resistors 120 Ohm.
No progress.
the program is in attachment. I change the extension of the file from 7z to Zip.
