3) System down prevention (slave station cutoff function)
Because the system employs the bus method, even if there is a remote station which goes
down due to power OFF, etc., it will not affect the communication with other functioning
stations.
Also, in the case of a module equipped with a 2-piece terminal block, the module can be
replaced during data link. (Turn off the power of a module to be replaced, then replace it.)
However, if a cable is broken, data link is disabled in all stations. (Refer to Section 5.11.2.)
4) Reserved station function
By setting a station which is not actually connected now (which is planned for connection in
the future) as a reserved station, the station will not be handled as a faulty station.
