Range
A Range Variable specifies a range of values between a minimum and maximum value. Each value can
be a number between -2
31
and +2
31
-1. The maximum value should be greater than the minimum.
Range Variables have one other parameter, which is calculated from the minimum and maximum values.
The de-bounce value, displayed after the maximum value, is used to provide a small measure of
hysteresis to prevent flutter.
Functions
Note: ALL FUNCTIONS ARE CASE SENSITIVE!!!
Note:
You can utilize
decimal,
hex, binary
,
and octal
integers for functions as exampled here:
CHAR(66) = CHAR(0x42) = CHAR(0b1000010) = CHAR(0o102) = ‘B’
The following functions are available for use when the expression check box is checked in one of the
supported actions. The following types of actions support expressions: Variable, Serial, IR Serial, HTTP
Post, Email, Log, and Telnet interpreting Values as Expressions
