There are two timers for supervising of the execute phase,
tStartMove supervises that the primary device starts moving after the execute output pulse is
tIntermediate defines the maximum allowed time for intermediate position. Figure

different pulse lengths. The pulses can also be set to be adaptive with the configuration
parameter
AdaptivePulse parameter will have effect on both execute output pulses.

It is always possible to make a substitution, independently of the position
indication and the status information of the I/O board. When substitution is
enabled, the other signals related to the position follow the substituted position.
The substituted values are stored in a non-volatile memory. If the function is
blocked or blocked for update when the substitution is released, the position value
is kept the same as the last substitution value, but the quality is changed to
"questionable, old data", indicating that the value is old and not reliable.
When the position of the SXSWI is substituted, its IEC61850-8-1 data object is
marked as "substituted", in addition to the substituted quality, but the position
quality of the connected SCSWI is not dependent on the substitution indication in
the quality, so it does not show that it is derived from a substituted value.
