Expansion Setting Area Section 4-3
DM words m+39 and m+40 enable the Expansion Setting Area and set it
to CIO 0005.
If the process value of input 1 exceeds the high limit alarm value, CPU
Unit bit CIO 2000.01 is turned ON (1). If the CJ1 PLC’s ladder program
is being executed in RUN mode or MONITOR mode, the input condi-
tion of CIO 2000.01 (2) will be reflected in CIO 4.01 (3) and sent to Out-
put Unit OC221 (4) where the alarm will be output.
If DM words D20039 and D20040 set CIO 0005 as the Expansion Set-
ting Area (5), CIO 5.01 is turned ON directly from the AD04U Input Unit
(6) and the alarm is output externally from Output Unit OC201 (7).
This is how the Expansion Setting Area settings can be used to set
alarm outputs without using the ladder program.
