command output pulse remains active until the timer tOpenPulsetClosePulse has
elapsed.
tOpenPulse is the output pulse length for an open command. If AdaptivePulse is set to
Adaptive, it is the maximum length of the output pulse for an open command. The
default length is set to 200 ms for a circuit breaker (SXCBR) and 500 ms for a
disconnector (SXSWI).
tClosePulse
is the output pulse length for a close command. If AdaptivePulse is set to
Adaptive, it is the maximum length of the output pulse for an open command. The
default length is set to 200 ms for a circuit breaker (SXCBR) and 500 ms for a
disconnector (SXSWI).

The SwitchType setting controls the evaluation of the operating capability. If
SwitchType is set to Circuit Breaker, the input OPCAP is interpreted as a breaker
operating capability, otherwise it is interpreted as a switch operating capability.

tStartMove is the supervision time for the apparatus to start moving after a command
execution is done from the SCSWI function. When the time has expired, the command
supervision is reset, and a cause-code is given.
During the tIntermediate time, the position indication is allowed to be in an
intermediate (00) state. When the time has expired, the command supervision is reset,
and a cause-code is given. The indication of the mid-position at SCSWI is suppressed
during this time period when the position changes from open to close or vice-versa if
the parameter SuppressMidPos
is set to On in the SCSWI function.
In most cases, the same value can be used for both tStartMove and tIntermediate as in
the source function. However, tStartMove may need to be increased to accommodate
for the communication delays, mainly when representing a circuit breaker.
