2.62 SPSA Function Block

Description
The SPSA label stands for Setpoint Scheduler Auxiliary Setpoint Block. This block is part of the
Setpoint Scheduler category. It looks like this graphically on the Control Builder.
Function
The eight setpoint outputs of the Auxiliary Setpoint block are set to the current step value. The current step
is an input to the block and must be connected to the step output of a Master Scheduler block. At the end of
a step, the outputs of the slave block go directly to the next step value. That is, Ramps are not supported.
Inputs
PGM = Current Program Number
SEG = Current Segment number
STA = Program State (Reset, Run, Hold, Ghold, Stop).
