CMP2A clear memory
How can I clear memory by removing battery & power down.
I try for three hours but the program is still there.
Please help
 
Cross Posted from MrPLC.com

You should be able to clear the program by downloading just an END instruction to the unit.

The method you describe will probably require at least 24 hours, possibly more.
In addition to the battery, there is also a capacitor that protects the memory.

Hope this will help.
 
Thanks gtsuport
With syswin I can upload the program but download does not work.

Syswin communications error
Mailbox error,

This is why I am doing the Battery option.
I think the problem is with PLC Setup but the unit does not acept any change in the setup
 
Use CX-Programmer and click on 'autoconnect'. Then you will know what the communications parameters are.
 
Thanks I only have SYSWIN 3.4 but how long will it take to clear memory by removing the battery?
Regards
