MVP 2023 kratmel Posted February 7, 2023 MVP 2023 Report Share Posted February 7, 2023 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, 2023 Report Share Posted February 8, 2023 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?
