PLC Program execution and monitoring

Program transferred from a PC to a PLC starts executing at the moment when you move from a Stop/Program mode to a Monitor or Run mode. When Monitoring function starts executing, some sections of the monitor will be shaded (see picture above), and this way you can follow program execution.

Monitoring is active during editing of some program segment, and is stopped at the moment when a changed section of the program is transferred into a PLC controller.
