(1) I/O allocations marked with an asterisk are not used in this programming
example.
(2) The pin numbers shown in the above table are the pin numbers of the D-
sub connector on the special BCD output cable (sold separately).
Read data is stored in the memory, as shown below.
IR 001
IR 011
IR 021
In this programming example, IR 00113 in the CPU Unit of the PLC is turned
ON to read the measurement value of the three Digital Indicators (A, B and C)
to the PLC and store them in the DM area. No matter how long IR 00113
remains ON, data is sampled only once for each of Digital Indicators A, B and
C.
