[DESIGN PRECAUTIONS]
!
DANGER
• When there is a communication error in the data link, the station where the communication is
occurring changes to the following status.
Construct an interlock circuit in the sequence program so that the system will operate on the
safety side using the communication status information.
There is the risk of an accident occurring due to output error or malfunctioning.
(1) All general purpose inputs from this CC-Link board (A80BDE-J61BT13) are turned off.
(2) All general purpose outputs from this CC-Link board are turned off.
• If a cable dedicated to the CC-Link is disconnected, this may destabilize the line, and a data link
communication error may occur in multiple stations. Make sure to create an interlock circuit in
the sequence program so that the system will operate safely even if the above error occurs.
Failure to do so may result in a serous accident due to faulty output or malfunctions.
• A failure in the CC-Link board may cause I/O to change to on status or off status.
Establish a circuit to be observed externally for those I/O signals that may threaten to cause
serious accident.
!
CAUTION
• Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100 mm (3.9 inch) or more from each other.
Not doing so could result in noise that would cause malfunction.
