I have a communications problem between my controller and the PLC. The PLC weight reading is higher than the reading displayed on the front of the controller. What could be the problem?
When I have a failed or suspected bad HI 2151/30WC, I swap out the unit to help isolate the problem. I do this by installing the current SMM into the replacement HI 2151/30WC. Then all the configuration and calibration information is supposed to be transferred. This should make for a fast and efficient transfer, but the problem is I am getting an ERREXC error displayed. Why do I get an ERREXC when swapping SMM?
