Equations
• Logic functions may be used in an equation that begins with a DEL or SDEL time-based function: however, they must appear
within parentheses following the time-based function.
Delay and duration times are in 24-hour format (HHMMSS); the allowable range is 00:00:00 to 23:59:59.
The "DEL" Function
Used for delayed operation.
Example: DEL(HH.MM.SS, HH.MM.SS,AND(L1M1,L1M140))
• The first HH.MM.SS is the delay time, the second HH.MM.SS is the duration time. If the argument -
AND(N01L1M1,N01L1M140) - in the example above activates, the function becomes true after the argument has been active
for the delay time, and continues to be true for the duration time as long as the argument stays active. If the argument goes
inactive during the delay time or the duration time, the function reverts to false and the timing would begin all over again if
reactivated.
• If duration time of zero is entered (00.00.00), the equation will evaluate true when the delay time expires if the argument remains
active throughout the delay time period.
• If no duration or delay is specified, then the function will follow the input argument, indicating true while it is active and false
when it is inactive. DEL assumes a value of false on reset.
The "SDEL" Function
A latched version of the DEL function.
Example: SDEL(HH.MM.SS, HH.MM.SS,N01L1M140)
• The first HH.MM.SS is the delay time, the second HH.MM.SS is the duration time. If the argument (N01L1M140 in the example
above) activates, the function becomes true after the delay time, and will remain active for the duration even if the argument
becomes inactive during either the delay or duration time.
• If delay time of zero is entered (00.00.00), the equation will evaluate true as soon as the argument (N01L1M140) activates and
will remain that way for the specified duration, even if the argument becomes inactive during that time.
• If no duration or delay time is specified, then the argument will not deactivate until reset, even if the argument becomes inactive.
The "TIM" Operator
The TIM function is used to specify activation on specific days of the week or year.
Examples:
TIM(7-11-06) will evaluate as true for 24 hours starting at midnight (00:00:00) on July 11, 2006.
TIM(MO,TU,WE,TH,FR,08:00:00,23:00:00) will evaluate as true at 8:00 AM and remain true until 11:00 PM (23:00) for the list of
days supplied.
TIM(MO,TU,WE,TH,FR,08:00:00) will evaluate as true at 8:00 AM and remain true until 23:59:59 of the current day for the list of
days supplied.
TIM(TU,07:45:00,18:30:00) will evaluate as true every Tuesday between 7:45 AM until 6:30 PM.
TIM(MO,TU,WE,TH,FR) will evaluate as true from Monday morning at 12:01 AM until Friday evening at 11:59:00 PM.
Logic Equation Syntax Example
OR(AND(L1D1,L1D4),AND(L2D6,L2M3,NOT(L2M4)),ANYX(2,L1M13,L1M14,L1M15))
Equation begins with a logic function - OR
67 Characters (maximum of 80) - includes parentheses and commas.
5 Logic Functions (maximum of 10) - OR, AND, AND, NOT and ANYX.
8 Arguments (maximum of 20 per logic function) - L1D1,L1D4,L2D6,L2M3,L2M4...
The equation contains no spaces.
Evaluating an Equation
To evaluate an equation, start from the innermost part of the equation and work outwards. For this equation to evaluate TRUE and thus
turn on any output mapped to it, the following conditions must be met:
OR(AND(L1D1,L1D4),AND(L2D6,L2M3,NOT(L2M4)),ANYX(2,L1M13,L1M14,L1M15))
These
have to be
ON
for this part to be TRUE
When this is TRUE
Then all outputs programmed with this equation will be turned ON.

These have
to be ON ... and this OFF
for this part to be TRUE
OR When this is TRUE
Any TWO of
these have to be
ON
for this part to be TRUE
OR When this is TRUE
