IC6 Operating Manual
 Inputs and outputs may be named on an I/O map display. Additionally on this
display, the outputs may be defined as normally open (NO) or normally closed
(NC).
 Logic statements may be chained together using the Statement ### Event.
These features, combined with layer based process sequencing, allow moderately
complex vacuum processing plants to be controlled without the addition of any
other intelligent machines. It is possible that a user may program certain layers
within the process definition whose only purpose is to trigger certain other internal
sequencing and/or external control events. These “dummy” layers execute very
rapidly if the pre and post deposit state times, rate, and final thickness values are
all set to zero.
Fourteen TTL inputs and eight relay outputs are standard. An additional fourteen
inputs and eight relay outputs are available with an optional I/O card. With a second
optional I/O card, eight more relays and fourteen open collector outputs are
available.
The IC6 has the capacity for 100 logic statements.
9.2 Editing the Logic Statements
Logic Setup is initiated by moving the cursor to the Logic heading on the Main
Menu and pressing MENU. This will invoke the Logic display (see
Figure 9-1 ). You
may return to the Main Menu display by pressing MENU again. Upon entry to the
Logic display, the cursor will be placed at the last referenced Logic statement.
There will be an indication for each statement programmed, (the > symbol next to
the statement number) and an indication that the statement is True (green color
change and three stars *** will be present).
Figure 9-1 Logic overview page
Logic statements that are "true" are indicated in green and with *** asteriks.
