SPS Block Function
The Master (SPS) block supports up to 8 ramp or soak outputs operating on a common time base. It accepts
one PV for each setpoint. Setpoint guarantee
is provided for the master (SPS) block setpoints with a single
symmetrical value for each setpoint output. You can assign a failsafe value for each setpoint.
Inputs
NPGM
= Program Number (when SET is ON)
NSEG
= Starting Segment Number (when SET is ON)
^SET
= Pulse Input to load PGM and SEG numbers

STRQ
= for connection to the STQR output of the STSW function block. (See
Figure 2-68
) The STSW
block encodes discrete inputs to a form that will convey change mode requests from the STSW block:
0.0 No Change
1.0 Jog State
2.0 Guaranteed Hold State
4.0 Reset State
8.0 Hold State
16.0 Run State
32.0 Advance state
Outputs
PGM
= Current Program Number
SEG
= Current Segment number
STA
= Program State (Reset, Run, Hold, Ghold, Stop).
