MVP 2021 kratmel Posted February 7 MVP 2021 Report Share Posted February 7 Is it CPU-for-Panel present? Panel cannot operate independently. CPU-for-Panel must be plugged into the back of a UniStream® HMI panel. The panel provides the CPU’s power source. The CPU-for-Panel comprises: 1 IO/COM Bus connector for interfacing Uni-I/O™ & Uni-COM™ modules 2 Isolated RS485 and CANbus ports3 Backup battery Quote Link to comment Share on other sites More sharing options...
ORSO2001 Posted February 8 Report Share Posted February 8 hi Mac9010 for what I saw from your programa all seems ok...maybe, as already suggested, the battery is low and the retained memory is not save...is the "time date" ok at every reboot?
