About Mr

Mr discusses PLC and automation issues for Allen Bradley, GE, Omron, Mitsubishi, Modicon, Panel View, RS View, ABB, Adept Robots, Cognex and others. Customers can also submit and download sample PLC code. If its BBS and knowledge base still cannot run a customer PLC, Mr suggests contacting PDF Supply and Electric for PLC maintenance and replacement. In GX artwork 2, if the customer changes the name of the global variable, then they must click the "reserve system variable" button, and then click the "reflect system variable database" button to allow all POU instance variables to be updated, but when they do, they get the message PNG as shown in the attachment.
