4-5 Ladder Programming Examples
4-5-1 RUN/STOP Sample Programming
The ladder programming example here is for the following execution condi-
tions.
• Using simple I/O allocation to allocate data in the 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).
Operation
• Executes RUN or STOP for the E5ZN Temperature Controller (to control
Unit 0, ch1).
• The bit in the first word + 2 words of the OUT Area allocated by default is
used as the RUN/STOP Bit (CIO 320200).
• RUN is executed when the RUN/STOP Bit (CIO 320200) turns ON for the
execution condition 000000, after which the Output Enable Bit turns ON.
When the RUN/STOP Confirmation Flag (CIO 330200) turns ON, the Out-
put Enable Bit turns OFF.
• STOP is executed when the RUN/STOP Bit (CIO 320200) turns OFF for
the execution condition 000100, after which the Output Enable Bit turns
ON. Then, when the RUN/STOP Confirmation Flag (CIO 330200) turns
OFF, the Output Enable Bit turns OFF.
