CompoBus/S Interface
The standard built-in CompoBus/S interface increases the PC’s I/O capacity,
reduces wiring, and saves space. Up to 32 CompoBus/S Slaves can be con-
nected to create a Remote I/O Link with up to 256 I/O points. It is easy to build
an efficient, long-range distributed system with less wiring by connecting
CompoBus/S I/O Terminals, Analog Terminals, Sensor Terminals, and Bit
Chain Terminals.
• The max. number of Slaves that can be connected through CompoBus/S
can be set to 16 or 32 Slaves. The following tables show how the max.
number of Slaves and communications mode settings affect the commu-
nications response time as well as the communications distance and
communications speed.
