Within the limitations shown by the syntax definitions, complex expressions
may be formed using the AND and OR operators. Expressions are limited to
what you could manually enter through the Timing Trigger menu. Regarding
parentheses, the syntax definitions on the next page show only the required
ones. Additional parentheses are allowed as long as the meaning of the
expression is not changed. Figure 12-2, on page 12-11, shows a complex
expression as seen in the Timing Trigger menu.
Example The following statements are all correct and have the same meaning. Notice
that the conventional rules for precedence are not followed. The expressions
are evaluated from left to right.
OUTPUT XXX;":MACHINE1:TTRIGGER:BRANCH1 ’C AND D OR F OR G’, 1"
OUTPUT XXX;":MACHINE1:TTRIGGER:BRANCH1 ’((C AND D) OR (F OR
G))’, 1"
OUTPUT XXX;":MACHINE1:TTRIGGER:BRANCH1 ’F OR (C AND D) OR
G’,1"
