Serial communications mode Characteristics
Peripheral Bus High-speed communications are possible. Conse-
quently, connecting via a peripheral bus is recom-
mended when using a CX-Programmer.
Only 1:1 connection is possible.
When using a CS-series CPU Unit, the baud rate of
the communications devices can be automatically
recognized for connection.
Host Link This is a communications protocol with a general-
purpose host computer.
Either 1:1 or 1:N connections are possible.
Host Link communications are slow compared with
the Peripheral Bus communications.
The following connections are possible: Via a
modem or optical fiber adapter, over long distance
using a RS-422A/485, and 1:N.
