I have S7-300 (315-2PN/DP) PLC with 2 CP-340 Cards. 34 Energy Meters are looped and connected to these CP Cards. I also have CP 343-1 Card to connect it to SCADA PC. Now I want to acquire data of these Energy Meter on my proprietary IOT Device. But it can only take data on Modbus RTU or Modbus...
I would like to acquire data for my IIOT- Device in G120 Drive and 6RA70 DC drive. But my IIOT hardware can only acquire data on Modbus RTU or Modbus TCP/IP. How can it be done? Is it possible without any additional hardware?
We have Danfoss VLT FC360. We want to fetch data on serial communication. The communication is established but we are still getting zero as a value in Modbus POLL Software. Not able to identify the issue.
Can the forum help on this?
