I/O Allocation
In the CPM2C-S, CompoBus/S input words IR 020 to IR 027 and CompoBus/
S output words IR 030 to IR 037 are allocated for the CompoBus/S Terminal’s
I/O. The CompoBus/S Terminal’s I/O (IN0 to IN15 and OUT0 to OUT15) are
allocated as indicated in the following table.
IN0 to IN15 are the node addresses for the Input Terminals and OUT0 to
OUT15 are the node addresses for the Output Terminals.
Note
1.
When the maximum number of CompoBus/S nodes is set to 16, IN8 to
IN15 and OUT8 to OUT15 can be used as work bits.
2.
CompoBus/S Terminals with less than 8 points are allocated bit addresses
from either 0 or 8, filling up from the lowest available word.
3.
CompoBus/S Terminals with 16 points can be set for only even number ad-
dresses.
