in position 1. Network communications will allow the sequencer to be moved to a new step and the remaining time
of the current step to be changed to a new value.
When discrete groups are used and a step is desired as 'timed only', one discrete input should be used to prevent the
input mask from moving the sequencer to the next step. This can be accomplished by requiring a high (1) input and
then not connecting that input, since unconnected inputs will be treated as 0.
When discrete groups are used and a step is desired as 'event only', the TIMe parameter for the step should be set to
0.0. The Analog Output will remain at the AEP value of the previous step or, if at step 1, the Analog value will be
0.0. When the sequencer advances to the next step, the Analog Output will go to the AEP value for the completed
step.
POWER UP - During a warm start, if PU LAST is set to YES, all outputs, step number, track variable, and
remaining step time will be initialized at the last values prior to power fail. During a cold start all outputs are
initialized to 0 and the PRSEQ is in a reset condition.
