Write Protection

4 posts in this topic

I have a new CP1H PLC that I need to download a program to it. I can connect to it and put it in Program Mode. However, when I try and execute the command to transfer from the memory cassette it comes back with the following:

"Write Protection is set"

"Password for UM read protection is set"

This is a new PLC and I haven't set any write protections on it. How can I get around this to allow the program to download to it?

Thanks, danvhp

Is DIPSWITCH 1 ON? Must be OFF to transfer program.

DIPSWITCH 1 is in the off position.

Update:

I cycled the position 1 DIPSWITCH and then turned position #2 on for an automatic download. Once I powered the PLC, it downloaded the program from the Memory Cassette and it appears to be ready to install. Great user forum by the way!
