UM Read Protection CS1 - how to remove

7 posts in this topic

Hi Guys, I am getting the UM REad Protection Message when trying to upload or edit a progam on a CS1. We have not put in password protection, and can only think somehow a lightning strike has caused this. Does anyone know how to overcome this when you do not have a password. This is a PLC I have edited many times, so a real scratchy head moment at present. Thanks in advance for any help anyone can give. Cheers Nick

Good to hear, what did you find the problem was? So often people seek help, then never post if they found a solution. The more solutions posted, no matter how simple they are, help others in the future.

It is possible to read-protect individual program tasks (called task read protec-
tion) or the entire user program (called UM read protection).
Read protection prevents anyone from displaying or editing the read-protected
set of tasks or entire user program from CX-Programmer without inputting the
correct password. If the password is input incorrectly five times consecutively,
password input will be disabled for two hours, providing even better security

Tasks and Function blocks can be individually password protected in the program whether ONLINE or OFFLINE.

UM read protection locks out ONLINE access to the PLC program.

You can use both.
