Description
Returns 1.0 when the digital input, digital output, or
alarm output has transitioned either from OFF to ON
or ON to OFF. When used as an equation for a one-
shot output, the result will be an ON (1.0) pulse for an
amount of time determined by the PW equation (see
Section 1.4.4,
Pulse Width Equations).
Returns 1.0 when the digital input, digital output, or
alarm output has transitioned from ON to OFF. When
used as an equation for a one-shot output, the result
will be an ON (1.0) pulse for an amount of time deter-
mined by the PW equation (see
Width Equations).
Returns 1.0 when the digital input, digital output, or

mined by the PW equation (see

Description
Returns a 1.0 if the minute has changed since the last
time the algorithm has been run. Otherwise, it returns
a zero. The result is a short ON transition about once
per minute. Parenthesis accepts no arguments, but
empty parenthesis must still be placed at the end of
this function name in the equation.
Returns a 1.0 if the hour has changed since the last
time the algorithm has been run. Otherwise, it returns
a zero. The result is a short ON transition once per
hour on or about the top of the hour. Parenthesis
accepts no arguments, but empty parenthesis must still
be placed at the end of this function name in the equa-
tion.
Returns a 1.0 if the day has changed since the last time
the algorithm has been run. Otherwise, it returns a
zero. The result is a short ON transition once per day
on or around midnight. Parenthesis accepts no argu-
ments, but empty parenthesis must still be placed at
the end of this function name in the equation.
Returns a 1.0 if the month has changed since the last
time the algorithm has been run. Otherwise, it returns
a 0.0. The result is a short ON transition once per
month at 12 midnight on day 1 of each month. Paren-
thesis accepts no arguments, but empty parenthesis
must still be placed at the end of this function name in
the equation.
