Telephone line RS-232C
• Use a Serial Communications Board or Unit; connect to a PLC via a modem; use
an instruction to switch to host link mode, and then program or monitor from the
CX-Programmer. (It’s not necessary to cut the connection during the procedure.)
• Use the host link gateway function to program or monitor any PLC connected to
a Controller Link or Ethernet Network to which the PLC connected to the
computer running the CX-Programmer is connected (via RS-232C).
Host Link
Programming and editing a PLC on a remote
network.
Network
• Use the gateway function to edit any PLC connect to a network up to two
networks away (3 networks including the local network). For example, a PLC on
the Controller Link Network shown below can be accessed from the
CX-Programmer running on a computer connected to a PLC on the Ethernet
Network.
