Rules for Logical Assignments
The following rules apply to logical assignments:
- Logic is case-sensitive. Use lowercase and capital letters as in the samples above.
- Spaces matter. Use spaces per the samples above.
- If a logical assignment consists of more than one line, each line should end in a carriage
return.
- The last line of a assignment must end in a semicolon.
- You can add comments to annotate your logic assignments. Single line comments begin
with //. Multi-line comments begin with /* and end with */.
- Many symbols can be written using C-Style programming commands. For example, “not
in1” can be written “!in1”.
The following symbols can be used in logical assignments:
Symbol Shorthand
not !
and &
or | (vertical line)
xor #
HIGH none
LOW none
( ) none
; none
Predefined Variables
timerPRO includes a number of Predefined variables to speed logic coding. To view the variable
names that are recognized by timerPRO, click Predefines on the Logic tab.
