description
Item to check
Point to check
Check method
Corrective action
The entire
system cannot
be data-linked.
Transmission
speed
Is the transmission speed out of
the setting range or is the
transmission speed of the bridge
module is different from that of
CC-Link remote stations?
Check the setting for the
transmission speed of each
station.
Set the transmission speed
correctly.
Mode
Is the mode of the bridge module
other than online?
Check the mode setting of the
bridge module.
Change the mode of the bridge
module to online.
Cables and
other devices
• Check the cable and other
tools for disconnection, short
circuit, incorrect wiring, poor
contact, and usage not
meeting the specifications
(transmission distance,
station-to-station distance,
coexistence of different types
of cables, and FG connection).
• Check if a transmission cable
other than a CC-Link
dedicated cable is used.
Check if there are any failures,
such as cable disconnection
between the bridge module and
slave stations.
Connect the cable correctly.
Is a terminating resistor
connected?
Check that terminating resistors
are connected to the farthest
ends of the CC-Link system.
Connect terminating resistors to
the farthest ends of the CC-Link
system.
Link start
Is the CPU module of the master
station in the RESET position?
Check if the RESET switch of
the CPU module of the master
station is in the RESET position.
Disable the RESET status.
Bridge module
check
Has any error occurred in the
bridge module?
Check the error codes of the
bridge module.
