- DI/DO
In a multi-path system, the interface signal address relations between
the CNC and the PMCs are as shown in the figure.
You can control all paths with a single PMC (Ladder program), or
control each path with a PMC (Ladder program), using the multi-path
PMC function (option).

NOTE
1 In a multi-path PCM system, each PMC has an independent signal area. The F,
G, X, and Y signal addresses of each PMC are allocated, starting with address 0.
In contrast, the F and G signal addresses as seen from the CNC are fixed
addresses in the same order as that of the path numbers. The F and G signal
addresses programmed by each Ladder program differ from the F and G signal
addresses as seen from the CNC.
2 The signal addresses relations between the CNC and the PMCs of each path can
be set with NC parameters Nos. 11920 to 11929. For details of how to do this,
refer to Chapter 1 of the PMC Programming Manual.
