If the configuration BTW and
diagnostic BTR are done, check
that the diagnostic table
parameters indicate a successful
BTW (word 36 and 37 equal 0).
If so, unlatch the configuration
mode bit and latch the setpoint
mode bit.
Rung 2:3
Initialize the sequencer for
setpoint mode. Same
functionality as Rung 2:0.
Rung 2:4
Move the number of setpoints
into the setpoint address
counter. Reset the setpoint
counter.
