[DESIGN PRECAUTIONS]
!
WARNING
For details on the operating status of each station when a communication problem occurs in the
data link, refer to Section 6.5 of this manual.
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.
When performing the control of the personal computer in operation (changing data), configure
an interlock circuit in a user program so the safety of the overall system is always maintained.
When performing other controls of the personal computer in operation (changing program and
operation status (status control)), read this manual carefully and confirm if the overall safety is
maintained.
Especially, when this control is performed to a remote personal computer from an external
device, problems that have occurred on the personal computer side may not be able to
immediately be handled if there is a data communication error.
Define a troubleshooting agreement between external devices and the personal computer for
data communication error occurrences, as well as construct an interlock circuit in the user
program.
Do not write any data from the user program into the "system area" of the board buffer memory.
Writing data into the "system area" may cause a CC-Link system malfunction.
A failure in the board may cause remote I/O not to turn on or off correctly.
For critical I/O signals that may cause a serious accident, establish a circuit to externally monitor
them.

(3) Local station communication
The communication between the master station and the local station uses two
types of transmission methods: cyclic transmission and transient transmission.
(a) Cyclic transmission
Data communication between stations can be performed in N : N mode
using bit data (remote input RX and remote output RY) and word data
(remote registers RWw and RWr).

(4) Intelligent device station communication
The communication between the master station and the intelligent device station
uses two types of transmission methods: cyclic transmission and transient
transmission.
(a) Cyclic transmission
Handshaking signals with the intelligent device station (positioning start,
positioning end, etc.) are communicated using the remote input RX and
remote output RY. Numeric data (positioning start number, present feed
value, etc.) is communicated using the remote registers RWw and RWr.

(5) System down prevention (Slave station disconnect function)
Even if a module system fails because of power failure or power off, it will not
affect the communication with other normal modules since the system employs
the bus connection method.
Also, for a module using a 2-piece terminal block, the module can be replaced
during data link. (Replace the module after turning its power off. Also check that
the switch setting on the replaced module is same as the one set on the module
before replacement.) However, if the cable is disconnected, the data link to all
stations is disabled.

(6) Auto return function
When a module that has been disconnected from the link due to power off
recovers and returns to the normal status, it will join the data link automatically.
(7) Input data status setting from a data-link faulty station
The data entered (received) from a data-link faulty station can be cleared, or the
status immediately before the error can be restored.
