Parameter
& Data Type Enter
TintoInt
constant The time into interval sets an offset from the datalogger’s clock to the
interval at which the IfTime will be true. For example, if the Interval is set at
60 minutes, and TintoInt is set to 5, IfTime will be True at 5 minutes into the
hour, every hour, based on the datalogger's real-time clock. If the TintoInt is
set to 0, the IfTime statement is True at the top of the hour.
Interval
constant The Interval is how often IfTime will be True.
Units The time units for TintoInt and Interval
Constant Alpha Code Numeric Code Units
Usec 0 microseconds
Msec 1 milliseconds
Sec 2 seconds
Min 3 minutes
Hr 4 hours
Day 5 days
IIF
The IIF function evaluates a variable or expression and returns one of two
results based on the outcome of that evaluation.
Syntax
Result = IIF(Expression, TrueValue, FalseValue)
Parameter
& Data Type Enter
Expression The Variable or expression to test.
Expression or Value Result
Variable
≠
0
True: return TrueValue
0 False: return FalseValue
TrueValue
Constant
Variable or
Expression The Value (or expression determining the value) to return if the test condition is true
FalseValue
Constant
Variable or
Expression The Value (or expression determining the value) to return if the test condition is
False
IMP
The IMP function is used to perform a logical implication on two expressions.
Syntax
result = expression1 IMP expression2
