2.4.6 Extended Digital Functions
2.4.7 Time and Date Functions
Function Description Examples
BOTHEDGE(input)
Returns 1.0 when the digital input 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)
BOTHEDGE(DI3)
BOTHEDGE(AND(DI1:DI4))
INVEDGE(input)
Returns 1.0 when the digital input has transitioned
either 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 determined by the PW equation
(see Section 1.4.4, Pulse Width Equations)
INVEDGE(DI3)
INVEDGE(AND(DI1:DI4))
EDGE(input)
Returns 1.0 when the digital input has transitioned
either from OFF to ON. 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)
EDGE(DI3)
EDGE(AND(DI1:DI4))

Function Description Examples
NEWMINUTE()
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.
NEWMINUTE() result: ON transition
once per minute.
NEWMINUTE result: ERROR (no
parenthesis)
NEWHOUR()
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.
NEWHOUR() result: ON transition
once per hour.
NEWHOUR result: ERROR (no paren-
thesis)
NEWDAY()
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.
NEWDAY() result: ON transition once
per day.
NEWDAY result: ERROR (no paren-
thesis)
NEWMONTH()
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.
NEWMONTH() result: ON transition
once per month.
NEWMONTH result: ERROR (no
parenthesis)
