Manuel Steven posted a topic in CX-ProgrammerHello, 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 Regards, Steven.
