Hello,

i have installed the above memory modules in two slc 5/05 plcs at work but two of the same plcs will no let me store the program to the eprom

the error that i get is that memory is write protected. I have tried two different memory modules new from the package but as soon as i try to load the program on the module it would show that the module is write protected and is not installed whereas actually it is present. Can someone suggest me something.

Processor details: 1747 - l552 os 501 series a

module details: 1747- m13 ser a rev a

regards

kanwar
