SoMachine M251 RAM Battery Monitoring

[ryanAstiefes]

How do I monitor the Ram Battery in SoMachine?

I've tried using the PLC_GVL.PLC_R.i_wClockBatterystatus on a GT block but I keep getting compiling errors. 

What must take place in order for me to be able to use this Variable in a POU?

HI @ryanAstiefes ,

You can try like this without the PLC_GVL:

But it also worked for me:

Maybe you will need to share the compiling error to know more about the problem. If it is related to the syntax , the variable or the block.

Best regards,

Leandro

Btw, just so you know, the battery is not for RAM, it is for the RTC clock only so PLC will not die at power loss without it 🙂
