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 IC/5 has the capacity for 100 logic statements.
6.2 Editing the Logic Statements
A series of conditional events and a related series of actions may be defined
through the Logic Statements. When the event string is determined to be true the
associated actions are executed in left to right order. The state of the Logic
statement is indicated on the Logic Directory display. Three small asterisks under
the Logic Statement number indicate the statement is true (active). The
expressions are evaluated in numerical sequence starting with logic
statement 1.
To initiate Logic Statement Set-Up, press function key F3 (I/O) in the Program
display; then press function key F1 (Logic Statement Directory). This will invoke the
Logic Statement Directory (see
Figure 6-1 ). Upon entry, the cursor will be placed at
the last referenced Logic statement. Entries for four statements are shown on each
display page.
