(2) Manual switch
While a submaster station is operating as a master operating station, the operation of the master station can be
switched from the submaster operation to the master operation with the procedure described below. Note,
however, that this does not apply when the master station is operating as a master operating station.
Cyclic transmission is continued during switch. (The output of the slave station is maintained during switch.)
1.
In the submaster station operating as a master operating station, check that Forced master switch
enable status (SB0066) is on. Then turn on Forced master switch command (SB0019).
Whether the submaster station is operating as a master operating station can be checked using the
following signals.
• Own station master/submaster function operation status (SB004E) is off.
• Master station information (SB0070) is on.
2.
When the master/local module receives a switch direction, Forced master switch acceptance
status (SB0067) is turned on, and the switch is started.
Cyclic transmission is continued during switch.
3.
When the switch is completed, Forced master switch operation status (SB0068) is turned on.
4.
The result can be checked in Forced master switch command result (SW005C).
5.
Turn off Forced master switch command (SB0019).
Forced master switch acceptance status (SB0067), Forced master switch operation status (SB0068), and
Forced master switch command result (SW005C) turn off.
