CompoBus/S I/O Master Functions (SRM1(-V2) and CPM2C-S Only)

2-12 CompoBus/S I/O Master Functions (SRM1(-V2) and
CPM2C-S Only)
Maximum Number of Nodes
Slave Interrupts
148
A maximum of either 16 or 32 CompoBus/S nodes may be connected.
Communications mode
High-speed mode g p
Long-distance mode g
The communications mode and maximum number of nodes are set in the PC
Setup, as shown in the following table.
Word Bit(s)
DM 6603 00 to 03
04 to 07
08 to 15
Note When changes are made to these settings, always turn the power off and on
again to make the new setting effective.
Input bits in IR 000 to IR 007 and output bits in IR 010 to IR 017 are used as inter-
rupts for CompoBus/S I/O Terminals. The CompoBus/S I/O Terminal interrupts
(IN 0 to 15 and OUT 0 to 15) 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
can be used as work bits.
2. CompoBus/S Terminals with less than 8 points are allocated bit addresses
from either 0 or 8.
