5.8 I/O No. Allocation Method
I/O no. allocation gives an address to each module in order to read data from input modules and output data to output
modules.
(1) Fixed 64 points are allocated to each module for I/O area, and the special and communication modules don’t allocate I/O
area. (The rests are available to use as internal relay.)
(2) The I/O allocation method is as shown below.
Output: %QX0.0.0 ~ %QX0.0.23 %QX0.1.0 ~ %QX0.1.3 %QX0.3.0 ~%QX0.3.3
