Description
The initial setting of a remote device station that was performed
on a program can be registered in advance using a
programmable controller and can be saved by turning on the
link special relay (SB). A program for the initial setting is not
required.
A request for the interrupt to a CPU module is issued when the
conditions that have been set using a programming tool are
satisfied, and the interrupt program can be executed. This
function is used to stop the control and execute an interrupt
program upon an error or for other purposes.
Data link can be performed by powering on the master/local
module. This function is used to check the operation of when a
system is configured.
Slave stations that are not actually connected (but will be
connected in future) are not detected as "Data Link Faulty
Station" in the master station and local station.
By setting slave stations that will be connected in future as
reserved stations, slave stations can be added without a
program change because the RX/RY/RWr/RWw assignment is
not changed. In addition, the number of points of a slave station
that has been set as a reserved station can be set as zero
points.
Even if a data link error occurs in a slave station, the station is
not detected as a faulty station in the master station and local
station. This function is used when a slave station is powered off
as a matter of the system configuration or for other purposes.
Even if a data link error occurs in a slave station, the station is
not detected as a faulty station in the master station and local
station. This setting can be configured even during data link,
unlike the error invalid station setting function.
This function is used to exchange slave stations during data link
for maintenance or for other purposes.
The time of setting parameters can be reduced by automatically
reading information of slave stations.
The model names of slave stations can be read.
The setting data of the slave 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 slave
module.
