Monitoring and Debugging

There are several ways to monitor and debug PLC operation, including the
force-set and force-reset operations, differentiation monitoring, time chart
monitoring, data tracing, and online editing.
Force-Set and Force-Reset
When necessary, the force-set and force-reset operations can be used to
force the status of bits and check program execution.
When a Programming Console is being used, monitor the bits with Bit/Word
Monitor or 3-word Monitor. Press the SHIFT+SET Keys to force-set a bit or
press the SHIFT+RESET Keys to force-reset a bit. The forced status can be
cleared by pressing the NOT Key.
