CQM1 and memory 80F1 error

[pjw 0]

Hi, first as I am new on this forum would like to say hello to all of you ;)

I appreciate some help what might help to make my PLC CQM1 work, it display ERR/ALM light and power, no other LEDs are not visible,

I've got in CXProgrammer memory error (from error list) 80F1,

does any one know how to fix it, I read few manuals and troubleshooting pdf and couldn't figure out how to fix it.

Someone has any idea?

Have a look in the manual for the PLC for what the error code means.

My suspicions are that it has lost memory but the PLC has been dead for years and should have been replaced years ago with a newer model.

I have not used one of these for over 10 years - parts are no longer available and they cannot be repaired.

I found out what was wrong, there was no memory card, and deep switch was set to use one, after disable this option and also another deep switch

for protection CQM is working ;)
