5.3.3 Logic: AND Gates
The GCE MCF provides 7 general purpose configurable AND gates. Figure 5-16 shows the
menu for assigning terms to AND 2.
The AND 2 Term 'n' can be any available System I/O value. For AND Gates 2- 6 terms 3 and 4
can be negated by setting the Not OR Term to Yes. For AND Gates 7 and 8 terms 2, 3, and 4
can be negated.
The term 1 is set FALSE and the remaining terms are set to TRUE by default, leaving any Term
at FALSE will result in the AND gate always being de-energized. When any Term is set to a
value other than FALSE, this AND will be available for use in the available System I/O and
System Outputs (see Section 10.1.6).
If not all 6 Terms are needed, and unused terms must be set to TRUE.
The AND gate also provides an optional Enable and Wrap function. If the AND 'n' Enable is set
to Yes, the AND 'n' Enable can be assigned as a System Input, e.g., mapped to a vital input on
a module. The Enable input has configurable pickup and drop delays, range 0-500 sec, default
0 sec.
If the AND 'n' Wrap is set to Yes, the AND 'n' Wrap can be assigned as a System Input, e.g.,
mapped to a vital input on a module.
