Note The CX-Programmer can be used for remote programming and monitoring. It
can be used to program and monitor not only the PLC to which it is directly
connected, but also to program and monitor any PLC connected through a
Controller Link or Ethernet network to which the PLC that the CX-Programmer
is connected to is a part of. All programming and monitoring functionality for
the directly connected PLC is supported for remote programming and moni-
toring, the PLC can be connected though either the peripheral or an RS-232C
port, and either the peripheral bus or Host Link bus can be used. Remote pro-
gramming is possible for up to three levels of networks (counting the local net-
work but not counting the peripheral bus or Host Link connection between the
CX-Programmer and the local PLC).

Not required.
Not required.
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.
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.
