Modbus driver warning

[Nuno]

Hi guys,

Proj_Version = 3.16

In this project we're; at the moment, using the Modbus driver to Poll information out of 100 PLC's via Modbus/TCP.
Communication between OA server and PLC's is working just fine. But I'm getting, every 10 seconds, an annoying Unexpected state WARNING on the logViewer:
..."Unexpected stat, ModModBusMaster, writeData, No host/unit addresss defined for PLC number: 0"





My PLC's are numbered from _Mod_Plc_1 to _Mod_Plc_100, I don't have any "PLC number: 0" configured! So where this is WARNING coming from???
Please let me know if you need any additional information about the project.

Best regards
Nuno

Sounds like you have an Adress with SPS 0 configured
