Error 88 hex. at D1352 when running program (CP1E to Power Meter PM2120)

[Manuel Steven 0]

Hello,

I've connect CP1E with PM2120 with RS485 and already make ladder program to read voltage, current, etc. But the problem is the binary value (D1354&1355) are not appear, and there's error in D1352 with error code : 88 hex. Which is the description of error code is "Exception response", and i already doing some experiment by just making a simple ladder with RXD/TXD instruction and put D1352 addresses and still error, which is same like before (88 hex.). Can i just still do something with this error?

Please help me to solved this error problem.

*Sorry for bad English
