3.9 Parallel input/output unit
・ A parallel input/output unit or card is mounted as a standard in the controller's control unit.
・ The external input/output circuit specifications are shown in Table 3-6 and Table 3-7.
・ The correspondence of the external input/output connector pin No. and the colors of the connected "external
input/output cable" wires (separate option) is as shown in
Page 61, "Table 3-8"and Table 3-9. Refer to Page
81, "(4) External I/O cable" for details of external I/O cable.
・ Pin Nos. described as both general-purpose signal and dedicated signal can be shared.
・ The other dedicated input/output signals that are not assigned can be assigned to required general-purpose
input/output pins when creating the program.
・If the standard inputs and outputs are insufficient, install the parallel input/output unit connection option outside
the controller.
