■Parameter setting
"Network Configuration Settings" of "Basic Settings" does not reflect the temporary cancellation of reserved station
specification.
■When the master station is reset or the system is powered off
The disabled reserved station setting is ignored, and the slave station returns to the status set in "Network Configuration
Settings" of "Basic Settings" of the master station.
■When a station for which the reserved station setting has been temporarily disabled is
disconnected from the network
The following status differs between the master station and local stations after the CPU module on the master station is reset
or the system is powered off.
• ERR LED status
• SW00C0 to SW00C7 ('Reserved station setting status') and SW0180 to SW0187 ('Reserved station cancel setting status')
The difference can be corrected by the following procedure.
1.
Reconnect the disconnected station.
2.
Disable the reserved station setting, and enable the reserved station setting again.
■Checking the station number of a reserved station
The station number of a reserved station can be checked in the "Reserved Station Function Enable" window.
■For execution in a redundant line configuration
Execute temporary cancel of the reserved station setting for stations on the networks of both systems. When this has been
executed only for a station on the network of one system, since temporary cancel of the reserved station setting has not been
executed for a station on the network of the other system, if system switching occurs, the state of not having executed
temporary cancel of the reserved station setting arises.
Enable/Disable Ignore Station Errors
A slave station not set as an error invalid station can be temporarily set as an error invalid station. This function is used to
temporarily prevent detection of an error in a slave station.
This function also cancels temporary error invalid station setting configured to a slave station.
The temporary error invalid station setting can also be configured/canceled using link special relay (SB) and
link special register (SW) of the master station. ( Page 294 List of Link Special Relay (SB), Page 314 List
of Link Special Register (SW))
