Reserved station function Prevents slave stations that are not actually connected (but will be
connected in future) from detecting 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, or 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 to zero points.
Error invalid station setting function Prevents a slave station from being detected as a faulty station in the
master station and local station even if a data link error occurs in the slave
station. This function is used when a slave station is powered off as a
matter of the system configuration or for other purposes.
Temporary error invalid station setting
function
Prevents a slave station from being detected as a faulty station in the
master station and local station even if a data link error occurs in the slave
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 for maintenance or for other purposes during data link.
Interrupt setting function Issues an interrupt request to a CPU module when the interrupt conditions
that have been set using an engineering tool are satisfied, and executes the
interrupt program. This function is used to stop the control and execute an
interrupt program upon an error or for other purposes.
Remote device station initial setting
procedure registration function
Registers in advance the initial setting of a remote device station which is
performed on a program using an engineering tool and saves the setting by
turning on the link special relay (SB). A program for the initial setting is not
required.
Master station duplication error
canceling function
Clears a master station duplication error without resetting the CPU module
or powering off and on the system when the error has been detected.
Transmission speed auto-tracking
function on local stations
Automatically tracks the transmission speed of the master station when the
own station is a local station or standby master station. This function
eliminates transmission speed setting errors.
