1.
Refer to the I/O allocations for each Master Unit in
for details
.
For details on the SRM1, refer to
the
CompoBus/S SRM1 Master Control Units Operation Manual
(W318).
For details on the CPM2C-S PLC, refer to the
CPM2C-S PLC Operation
Manual
(W377).

Main Line/Branch Line Connections
This section describes the connections to the main line and branch lines in the
CompoBus/S System. When the system has a main line distinguished from
the branch lines, the CompoBus/S communications cable is made with the
main line and branch lines. The main line connects the Master and the termi-
nator while the branch lines are branched from the main line. The main and
branch lines are different in usage but they are the same cable type. When the
system has no main line distinguished from the branch lines, the communica-
tions cable can be connected with no special restrictions.
