Ladder Programming Examples Section 4-3
Remote I/O Com-
munications
Operation • First, the Output Enable Bit is turned ON. The hexadecimal values are set
to D1000 and D1001 at the start of the ladder program. These values pre-
pare the channel 1 RUN operation command 0100 hex and the STOP
operation command 0101 hex.
• RUN is executed for channel 1 when CIO 000000 turns ON.
• The contents of D1000 (= 0100 hex) is copied to CIO 3209, where the
operation command is allocated.
• The strobe is turned ON (strobe 1 = 0 and strobe 2 = 1) and the operation
command is executed. The RUN/STOP status is checked and the strobe
is disabled for RUN (to prevent unintentional setting changes.)
• STOP is executed when CIO 000100 turns ON. The contents of D1000 (=
0100 hex) is copied to CIO 3209, where the operation command is allo-
cated.
