Mode
Note If the Startup Mode is set to PRCN (Programming Console's mode switch) but
a Programming Console isn't connected, the CPU Unit will start in RUN mode.
Change the PLC Setup from the default value to start in MONITOR mode or
PROGRAM mode when the power is turned ON. (The CS-series CS1 CPU
Units, however, will start in PROGRAM mode under the same conditions.)
Some of the Power Supply Units (the C200HW-PA204R, C200HW-PA209R,
CJ1W-PA205R, and CS1D-PA207R) are equipped with a RUN output. This
output point is ON (closed) when the CPU Unit is operating in RUN or MONI-
TOR mode and OFF (open) when the CPU Unit is in PROGRAM mode.
This RUN output can be used to create an external safety circuits, such as an
emergency stop circuit that prevents an Output Unit's external power supply
from providing power unless the PLC is on.
Note When a Power Supply Unit without a RUN output is used, an equivalent out-
put can be created by programming the Always ON Flag (A1) as the execution
condition for an output point from an Output Unit.
