switch.
There is a message display bar at the bottom-left of the Device Monitor screens.
Messages are displayed in this area to assist in operations or indicate errors.
When the Device Monitor function is being used, an error screen will be dis-

(such as a communications error). Press the error screen’s OK touch switch to
restart the Device Monitor function.
If the Device Monitor function was called by switching screens during operation,
the PT will revert to the screen that was displayed when the Device Monitor func-
tion was called.

clear the forced status of bits and timer/counter Completion Flags.
Reference:  When the PC is in RUN mode, it is not possible to change word PVs or force-
set, force-reset, or clear the forced status of bits (including timer/counter Com-
pletion Flags.)
 A word or bit address that has been specified will remain valid until the PT is
turned OFF or reset. The settings will remain valid even if the Device Monitor
function is closed, so the last valid settings will be displayed the next time that
the Device Monitor function is started.
