System Overview
The CompoBus/S System is a remote I/O communications system with
reduced wiring that retains the functionality and ease of use of the original
remote I/O system (wired type), while providing higher-speed, longer-dis-
tance, and highly reliable communications.
The CompoBus/S System allows connection of up to 32 I/O devices (Slaves)
to a Master Unit using only two signal wires, even on long production lines that
require multiple I/O control.
Connect up to 32 Slaves
(256 Points) for Each
Master Unit
Each CompoBus/S Master Unit can be connected to up to 32 Slaves of vari-
ous types, including I/O Terminals and Sensor Terminals, and allows I/O com-
munications for up to 256 points (128 inputs, 128 outputs).
Flexible Wiring Configuration
I/O Data Exchange without
Special Programming
I/O data can be exchanged between the Master and Slaves without requiring
any special ladder programming for communications. I/O information for each
Slave is exchanged between Slaves and the corresponding I/O Area in the
Master by simply setting the node number of each Slave.
