(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 000
In this programming example, IR 00113 in the CPU Unit of the PLC is turned
ON to read the measurement value of the Digital Indicator to the PLC and
store it in the DM area. No matter how long IR 00113 remains ON, data is
sampled only once.
