Function Blocks
SPS Setpoint Scheduler Function Block
Inputs
ENABL= Level input to enable the block. Only checked in ready state.
Input is ignored if not connected.
NPGM = Program Number (when SET is ON). See ATTENTION below.
NSEG = Starting Segment Number (when SET is ON). See ATTENTION below.
^SET = Pulse Input to load NPGM and SEG numbers. See ATTENTION below.

STRQ = for connection to the STQR output of the STSW function block. (See
block encodes discrete inputs to a form that will convey change mode requests from the STSW block:
0.0
1.0
2.0
4.0
8.0
16.0
32.0
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 Scheduler 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 Scheduler only when ^SET goes through a positive transition.
