9.6 Canceling/Restoring Reserved Station Setting
● Parameter setting
The network parameter does not reflect the temporary cancellation of reserved station specification.
● Resetting the master station (safety station) or powering off the system
Temporary cancellation of reserved station setting is reset, and the slave station returns to the status set by the network
parameter of the master station (safety station).
● Disconnecting a station for which reservation has been temporarily cancelled
If the safety CPU module on the master station (safety station) is reset, or the system is powered off, the master station
(safety station) and local stations will differ in the following:
• ERR. LED status
• Reserved station setting status (SW00C0 to SW00C7) and Reserved station function disable status (SW0180 to
SW0187)
The difference can be corrected by the following procedure.
1. Reconnect the disconnected station.
2. Temporarily cancel the reservation and then reserve the station again.
● Checking the number of a station specified as a reserved station
The number of a station specified as a reserved station can be checked in the "Reserved Station Function Enable"
window. ( Page 144, Section 9.6 (2))
Remark
A reservation for a slave station can also be temporarily cancelled/reset using link special relay (SB) and link special register
(SW) of the master station (safety station). ( Page 221, Section 11.3)
