(2) Precautions when preparing a cable
(a) Cable length
The maximum distance (between GOT and
controllers) of RS-422 cable must be 13m or less.
(b) Connector conversion box side connector
For the Connector conversion box side connector,
refer to the following.
6.7 Connector Conversion Box
(c) KEYENCE PLC side connector
Use the connector compatible with the KEYENCE
PLC side module.
For details, refer to the KEYENCE PLC user's
manual.
(3) Connecting terminating resistors
(a) GOT side
When connecting a KEYENCE PLC to the GOT, a
terminating resistor must be connected to the GOT.
Set the terminating resistor setting switch of the
GOT main unit to "Disable".
For the procedure to set the terminating resistor,
refer to the following.
