Posted 9 Jan 2020 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 Share this post Link to post Share on other sites
Posted 9 Jan 2020 Is DIPSWITCH 1 ON? Must be OFF to transfer program. Share this post Link to post Share on other sites
Posted 9 Jan 2020 DIPSWITCH 1 is in the off position. Share this post Link to post Share on other sites
Posted 9 Jan 2020 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! Share this post Link to post Share on other sites
