Hello Damayanti; How familiar are you with Modbus/TCP communications? Start with basic information on Modbus/TCP instructions for the S7-1200 PLC, prepared by our friend and specialist Pegaia: Tips and sample program for MODBUS TCP Next, in the following manual, Manual SENTRON Power Monitoring Device PAC3200, look at this section to find out what Modbus addresses are linked to the measured variables: 3.9.3 Modbus measured variables with the function codes 0x03 and 0x04 Then start planning your Modbus requests from the client (your S7-1200 PLC) to the server (the PAC 3200). Study the following pages from the Application and Tools section of Product Support: Measuring& Control S7-1200 Set 22: Data Communication between S7-1200 and SENTRON PAC3200 via MODBUS TCP Even if the code is limited to TIA Portal v.12, the documentation should give you a good start. Hope this helps, Daniel Chartier |

Hello Damayanti, I recommend to set start_address= 40002, length = 6 and MB_Unit_ID = 1. Regards, Kaulquappe |
