(3) List of the "handy functions"
Programs for the initial setting become unnecessary, since the
initial settings in the remote device station are set at the network
parameter. The initial settings in the remote device station can
be configured easily.
Since the interrupt program of the programmable controller CPU
is executed according to the established event issuance
conditions, high speed data receive processing can be made
without being influenced by the sequence scan.
The CC-Link starts automatically, only by turning the power on,
and the operation at the system construction can be checked.
By setting slave stations that will be connected in the future as
reserved stations, they will not be treated as data link faulty
stations.
Prevents slave stations that may be powered off in the system
configuration from being treated as data link faulty stations by
setting the network parameters.
Changes slave stations without detecting errors during online
operation.
Also, prevents slave stations, which are turned off in the system
configuration, from being treated as data link faulty stations
temporarily.
Selects whether to synchronize or not the link scan with
sequence scan.
In the synchronous mode, the link scan is performed
synchronously with the sequence scan. Therefore, the output
data can be sent in high speed.
In the asynchronous mode, the link scan is performed not
synchronized to the sequence scan. Therefore, a high speed link
scan can be performed independent of the sequence scan.
Stops or restarts the data link that is being executed.
By stopping the data link, the program debug can be performed
efficiently, since data from other stations are not received, and
data are not sent from the host station.
Allows the I/O points of the remote I/O stations to be selected
from among 8 points, 16 points and 32 points, reducing the
number of reserved points.
The refresh device points of the programmable controller CPU
and the link refresh time can be saved.
Master station duplication errors can be canceled without turning
the power supply off to on, or without resetting the
programmable controller CPU.
When the host station is a local station or a standby master
station, an auto following occurs according to the transmission
speed of the master station, what eliminates setting errors of the
transmission speed.
Logs the data link status of all stations.
When multiple stations repeat normal/faulty, or when determined
stations and later repeat normal/faulty, this function enables
easy identification of the causes, such as contact failure of the
cable, or the noise occurrence location.
