Mobile Console can be connected without the Head (Photoelectric Sensor
setting, teaching, and adjustment can be executed on site.)
Analog Input Terminals
Convert analog inputs to binary data.
The number of analog input points can be switched between 4 points, 3
points, 2 points, and 1 point using a DIP switch.
The following input ranges are supported:
0 to 5 V, 1 to 5 V, 0 to 10 V, –10 to 10 V, 0 to 20 mA, 4 to 20 mA
Analog Output Terminals
Convert binary data to analog outputs.
The number of analog output points can be switched between 2 points
and 1 point using a DIP switch.
Supports the following output ranges:
1 to 5 V, 0 to 10 V, –10 to 10 V, 0 to 20 mA, 4 to 20 mA
I/O Link Terminals for CPM1A/CPM2A
Create I/O Links (8 inputs, 8 outputs) with CPM1A and CPM2A PLCs.
CPM2C I/O Link Unit
Creating I/O Links (8 inputs, 8 outputs) with CPM2C-series PLCs.
1-2-2 CompoBus/S System Components
System with Distinct Main and Branch Lines
The diagram below shows a CompoBus/S System in which the main line must
be distinguished from the branch lines under either of the following conditions.
The system operates in High-speed Communications Mode.
The system operates in Long-distance Communications Mode with 2-conductor
VCTF cable. (The maximum length of the main line varies with the
type of communications cable.)
Master The Master administers the CompoBus/S System and manages the external
I/O of the Slaves. There is only 1 Master in a CompoBus/S System and the
Master must be connected at the end of the main line, as shown in the preceding
diagram.
Slaves The external I/O connected to the Slaves is processed by communicating with
the Master through the CompoBus/S System.
Main/Branch Lines The main line is the main cable that connects the two most distant points of
the system. Cables branching from the main line are known as branch lines.
Cables CompoBus/S communications are transmitted through 2-conductor VCTF, 4conductor
VCTF, or Special Flat Cable. When 4-conductor VCTF or Special
