Hi, I have similar case. As per system, am getting "wh" reading from 3rd party E-Meter over modbus rtu. PLC is S7-1200. As per observation, after certain value ; values are not updating in PLC. After 2-3 hours it is updating again. But it is not same as shown in the meter display. The value receiving is REAL value. Engineer could see the proper value update using modscan. But in PLC it is not updating. This also because of the REAL DATA TYPE LIMITATION? How can i go further ? ------------------------------------------------------------------------------------------ |

How are you handling the conversion from your e-meter real to s7-1200 real representation?

Hi! I'm facing similar problem, all Energy meter Values updating except KWH e but with random intervals more than 2-3 hours, In ModScan I can see values are updating for all, does anyone have a solution to this problem.
