Function Blocks
SPP Function Block
344 HC900 Hybrid Control Designer Function Block Reference Guide Revision 11
2/07
PV3 = Process Variable #3 value in engineering units, for deviation check.
Aux PV = Aux PV for Aux PV Display.
ENABL = Level input to enable the block - only checked in Ready State; input is ignored if not
connected.
NPGM = New profile number (1 to 70). See ATTENTION below.
NSEG = New start segment number (1 to 99). When connected, it is used in conjunction with the SET
input of the block to set the current segment of the profile to the value of NSEG. See
ATTENTION below.
^SET = Pulse input to load NPGM and NSEG numbers. See ATTENTION below.
^JOG = Pulse input to Jog to a predefined segment.
RSTRT = Pulse input for restart action after power interruption [For example, see HExample 5 -
Controlled Restart after Power Loss (page
H352).]
GHOLD = Guaranteed soak hold - changes program state from RUN to GHOLD when turned ON and
GHOLD to run when OFF.
^RESET = Pulse input RESETS program, when turned ON.*
^HOLD = Pulse input puts program in HOLD, when turned ON. Run needed to restart.
^RUN = Pulse input puts program in RUN, when turned ON; except when program is in GHOLD
state.
^ADV = Pulse Input for advance of segment.
*For example, see HExample 3 - Alternate methods for actuating SP programmer START/HOLD/RESET
functions (page
H350).
ATTENTION
If either or both NPGM and NSEG are connected directly to analog variables, when that
analog variable changes (for example: via a recipe load), then the Setpoint Programmer block
will immediately use the new value internally.
If NPGM or NSEG is connected to any other function type then their values are loaded into the
SP Programmer only when ^SET goes through a positive transition.
Output
SP
= Programmed setpoint value in engineering units
AUX = Second non-ramping auxiliary setpoint output in engineering units. [For example, see
HExample 4 - Using the setpoint programmer AUX output (page H351).]
STMR = Time Remaining in current segment - in minutes.
STME = Time Elapsed in current segment - in minutes.
PTME = Time Elapsed in program - in minutes
GHOLDI = Guaranteed soak hold indication - turns on if PV is outside guaranteed soak band and
Guaranteed Soak is enabled.
