Original Ć June 1990CE4.2:CL6211
The DCPs FST must be configured to provide the filtering action. The
following FST instructions illustrate the proper technique for
implementing the filtering action.
LOOP (’POINT–1’)
AIN (1)
OVRD (ENABLED, ’TRACK–REG’, TIFMAN (’SS–LOOP’),
SSLD (’SS–LOOP’, 2))
CNTRL
STAT
END
LOOP (’POINT–2’)
AIN (2)
OVRD (ENABLED, ’TRACK–REG’, TIFMAN (’SS–LOOP’),
SSLD (’SS–LOOP’, 1))
CNTRL
STAT
END
LOOP (’SS–LOOP’)
SGSL (VOLD (’POINT–1’), ACCUM, ACCUM)
CNTRL
STAT
AOUT (2)
LL (1.0, 0.0, time_constant, TIFMAN ( ’SS–LOOP’ ))
RGST (’TRACK–REG’)
END
Where:
time_constant = 1 / reset of the fast" loop
TRACK-REG = is an intermediate storage register, whose
value is fed into the OVRD function block of the upstream
controllers
SS-LOOP = the tag of the signal selector point
