Hello,
I established a Modbus TCP/IP communication between AVEVA Plant SCADA and a M221 PLC from Schneider.
Everything works correct until I want to exchange some Real values. I use MODNET30 Protocol and use %MW to determine the addresses but I think it's necessary to swap somehow the values in SCADA, because:
My Real TAG in Aveva have the address %MW38 when I write value 1 from AVEVA to M221 I receive in M221 at the address %MW39 value 16236
AVEVA value: %MW39 = 1.1 in PLC at %MW38 = -13107 and %MW39 = 16268
Can somebody offers me some support on this problem?
Also if I need to comunicate with M240 what Protocol it's necessary to use? MODNET30 ?
