Example 5 - Using the setpoint programmer AUX output
The Auxiliary output of the Set Point Programmer (SPP)
block can be used to drive the RSP of a secondary PID
control block on a level basis. This precludes the use of
another SPP block. A different (or same) set point can be
configured for each programmer step. This can be used to
program pressure, %C, etc. for a second control loop. Both
PID loops can be shown on the same SP Programmer
display. The PV for the secondary PID block is connected
to the top right pin of the SPP block to allow view of the
PV on the SP Programmer display.
