Data no retained on PLC when should

[Mac9010]

Hello everyone 

I have a problem with a program, the situation is the next,

When there is a sudden power outage my plc shuts down but when it is reset it does not retain the setpoint values that were previously loaded.

 

I have already checked if the values are retained and indeed if they are retained

 

Cold you give some advice or tell me what can I do to solve this issue? 

the cpu is USP-070-B10/B  and the software is the next. 

Thanks in advance.

Is the battery installed?, is it good?

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 ports
3 Backup battery

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?
