Connecting to a PLC Section 2-2
to the PLC. The characteristics of the network protocols are as shown be-
low.
Connection Methods
Use one of the following methods to connect the personal computer (CX-
Motion-MCH) and PLC (CPU Unit). It is also possible to connect the personal
computer to the port on the CS/CJ Series Serial Communications Unit. In that
case, the only network type that can be used is Host Link.
Connection Cables
Note When connecting the connectors of the above cables to the PLC's RS-232C
port, discharge any static build-up (e.g., by touching a grounded metal object)
before touching the connectors. Although XW2Z-
@@@ S-CV Cables use the
anti-static XM2S-0911-E Connector Hood (thus reducing the possibility of
static build-up), be sure to discharge any static as a safety precaution.
Network type Characteristics
Toolbus Faster communications. If possible, use this network type.
• For CS/CJ Series, the baud rate on the peripherals can be
detected automatically, and be connected.
• Only 1 on 1 connection possible.
• For CX-Motion-MCH, it can also be connected to a modem.
SYSMAC WAY
(Host Link) Used for communications with general host computers.
• Slower than Toolbus.
• Not only 1 on 1 connection, but also 1-many connection
possible.
• Connecting to a modem and optical adaptor possible.
