M172 PLC PROBLEM OF WRITING VALUE WITH EEPROM VARIABLE MOVE

[kryunl]

GREETINGS
M172 PLC
I NEED TO MOVE DIFFERENT VALUES
IN THE PLC
OTHER THAN THE VALUE TO BE WRITTEN FROM HMI TO THE EEPROM VARIABLE
BUT I GET AN ERROR I CANNOT MOVE I WOULD BE HAPPY IF YOU CAN HELP

Hello,

if you want to assign a value to an EEprom variable you have to use the target functions:

sysWritePar<type>()

e.g.:

sysWriteParReal(ADR(eepromRealVar),rNewValue);

These functions make an internal check to verify if the newValue is different from the one currently stored in order to perform an EEprom update only when it is really necessary

Thank you ( fbd ) can you share it visually please
and can I test it in hardware-free simulation or is hardware absolutely necessary
I cannot write data to eeprom variable in hardware-free simulation as in the visual

Federico Thank you ( fbd ) I did it as in the image and it worked
and I can test it in a simulation without hardware

You have to add to the adress input the FC ADR. It should look like this
