The CompoBus/S System settings are described in this section.
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).

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 control,
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 outputs).
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 communications.
A model number with the suffix “-DRT” means that the model also supports
DeviceNet Slave functions, thus enabling I/O linking with the DeviceNet Master.
