Allows the initiation of an APS switch command on the APS group and channel specified by the index values. When read this object returns the last command written or clear(1) if no command has been written to this channel since initialization. The return of the last command written does not imply that this command is currently in effect. This request may have been preempted by a higer priority local or remote request. In order to determine the current state of the APS group it is necessary to read the objects apsStatusK1K2Rcv and apsStatusK1K2Trans. The value lockoutOfProtection(2) should only be applied to the protection line channel since that switch command prevents any of the working channels from switching to the protection line. Following the same logic, forcedSwitchProtectToWork(4) and manualSwitchProtectToWork(6) should only be applied to the protection line channel. forcedSwitchWorkToProtect(3) and manualSwitchWorkToProtect(5) should only be applied to a working channel.
