Description
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 device stations that will be connected in the future as reserved
stations, they will not be treated as data link faulty stations.
Prevents device stations that may be powered off in the system
configuration from being treated as data link faulty stations by setting the
network parameters.
Changes device stations without detecting errors during online operation.
Also, prevents device 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-
tracking 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.
The time of setting parameters can be reduced by automatically reading
information of device stations.
The model names of device stations can be read.
The setting data of the device station is backed up into the SD memory card
of the CPU module on the master station.
The setting data backed up into the SD memory card of the CPU module on
the master station is restored into the device module.
