1747 - L532C SLC 5/03 fault

5 posts in this topic

Hi guys,

I am having an issue with SLC 1747-L532C.

It loses its program when it loses power.

So i downloaded a program again and put the key in RUN mode.

I got a fault and it says "The required memory module is absent or S:1/10 or S:1/11 is not set as required by the program."

Can someone tell me how to fix this issue?

Thanks

If you haven't removed the memory module I've had this when the power supply is faulty.  It powered up (there was a slight delay noticeable) but it dumped the program.  Changing the psu fixed the issue.

Of course the memory module could be faulty also.

Thanks for the replies :) 

The CPU has this memory module.

Should i replace this module?

Try removing the memory module then download the program again.

If the error goes away then you can decide whether to replace the module or not. You'll need to perform a 'Store to EEPROM' if you get a new module. The memory module is not required.

Verify the power supply jumper is set to the correct voltage otherwise the processor will behave badly
