Settings
The CompoBus/S System settings are described in this section.
Usable Node Number
Settings
Usable node numbers are set from a Programming Device by specifying
either of the following values as BCD in data memory (bits 0 to 3 of DM6603).
Note
The setting is read when SRM1 is started. After changing the setting, be sure
to restart SRM1.
Communications Mode
Setting
The communications mode is set from a Programming Device by specifying
either of the following values as a BCD in data memory (bits 4 to 7 of
DM6603).
Note
Long-distance Communications Mode can only be set in the SRM1-C0
@
-V2.
Earlier models (SRM1-C0
@
, SRM1-C0
@
-V1) cannot use this mode.

CPM2C-S Series CPM2C-S

C (-DRT)
The CPM2C-S Series is a small PLC based on the CPM2C Series with built-in
CompoBus/S Master functions. The CPM2C-S Series, like the CPM2C
Series, incorporates a variety of functions, such as pulse synchronous con-
trol, input interrupt control, high-speed counters, pulse outputs, and clock
functions.
Up to 32 CompoBus/S Slaves can be connected to the CPM2C-S Series to
construct an I/O link system with up to 256 points (128 inputs and 128 out-
puts). With CompoBus/S Slaves, such as CompoBus/S Remote Terminals,
Analog Terminals, Sensor Terminals, and Bit Chain Terminals connected, the
CPM2C-S Series saves wiring effort and supports long-distance communica-
tions.
A model number with the suffix “-DRT” means that the model also supports
DeviceNet Slave functions, thus enabling I/O linking with the DeviceNet Mas-
ter.
