With the CS1W-DRM21 and CJ1W-DRM21DeviceNet Units, operation com-
mands are made ready for execution by writing to the allocated words
(CIO 3209 when the default I/O allocation (fixed allocation area 1) is set.)
Operation commands are executed only when the Output Enable Bit is set to
1 (ON) and the strobe is ON. The strobe is ON when the following two condi-
tions are met:
1.
Strobe 2 = 1 and strobe 1 = 0
2.
The strobe was cleared after the previous operation command was exe-
cuted.
Note
Software resets are executed again even if the strobe has not been cleared.
Therefore the Output Enable Bit or the strobe must be cleared after the soft-
ware reset command has been sent.

RUN/STOP Sample Programming
The RUN/STOP ladder programming example here is executed under the fol-
lowing conditions.
• Using default I/O allocations to allocate data in fixed allocation area 1 of a
CS/CJ-series DeviceNet Unit (OUT Area = CIO 3200 to CIO 3263, IN
Area = CIO 3300 to CIO 3363).
Outline
This ladder programming example executes RUN and STOP for the E5AR/
ER-DRT. RUN and STOP are executed using operation commands.
Output Enable Bit (CIO 320100) and strobe are used to execute the operation
command.
