West Control Solutions KS98-1 - Manual (Page 212)

As the throughput times with a search run dependent on the number of segments may be very long, searching is limit -
ed to several time slots so that searching is done only in one segment per time slot.
A search run is done in the following cases :
• Search run at program start: search over several segments up to the next gradient change
• search run started via control input, interface or via operation: forward and backward search from the
actual program point to the next gradient change
• Search run after power failure at PwrUp = 1: forward and backward search from the point of failu-
re to the next gradient change
• Search run after power failure at PwrUp = 2: forward and backward search from the program time
in which the program would be without power failure until the next gradient change
• Search run in the hold segment (Gradient =0): A search run is done only if there is min. one further seg -
ment (except hold segment) in this section. With a further hold segment directly before or behind this
segment, the search run takes place only in the actual segment.
+ Search run at TPrio = 1 (time priority): The search run is limited to the actual segment, i.e. the runs from the actual pro -
cess value to the segment end value within the actual remaining segment time.
+ Segments with wait status at the end do not limit the search range, exept it 's the search run after voltage failure!
+ A search run may lead to program termination.
Analog programmer operating page
Analog programmer APROG has an operating page, which can be selected in the operating page menu with input

ring, operation (change) of this input field is not possible.
