lvarga Posted January 4, 2014 Report Share Posted January 4, 2014 Dear Unitronics, About 2 months ago I use JZ20R31. Today I wanted to upload a new program, but can not access the PLC, who writes that the PLC is locked. How do I unlock the lock? I didn't set any password.How to configure the PLC password protection? Thank you for your help, Best regards, Laszlo Quote Link to comment Share on other sites More sharing options...
