Control Group 25
Step “Ready”
Group has the ability to re-start, if step 4 “Ready” is active. Step Ready, is
active, until Group (restart) is started again. When step Ready is active, there is
a blue indication on the HMI Control- Group Popup. If the Group is restarted
with the Start button, it jumps directly to step 1 “Startup”. During this
re-starting situation, the Automatic Signal “EnAuto(X/Y)” is always true.
Only the Signal “EnAutoStart”, stays false during step 1+2 (Startup+Waiting)
and will pass over to true, if you remain at step 3 “Starting”.
The step controller not only increments steps consecutively, but may switch
(jump) to any step, in order to set a status, that complies with the new
situation. As an example, an operator Immediate Stop will, regardless of the
current status, immediately select status 0 and shutdown any control within the
group. The table below shows the additional jumps.
