24 Control Group
Group Sequence Step
Controller
The central part of the CtrlGrp is a seven-step controller, of which status is
available to the user. The steps 0..6 shown below, represent the actual group
status, in automatic mode. Status 0 is stopped, a normal start/stop sequence
runs the steps from 1 through 6, one after the other, and terminates at status 0,
if the group is stopped again.
Note: An additional status "Standby" is shown for information only and has
no influence on the sequence described. The state -bit, can be used in the
application as a memory flag, to trigger an automatic start of the sequence.
