Link types

For entering formulas, you can use different functions from the following mathematical areas:

Range	Expression	Function
Arithmetics	Basic functions
	+	Addition
	-	Subtraction
	*	Multiplication
	/	Division
	^	Exponential calculation
	SQRT	Square root
	()	Brackets
Trigonometry	Trigonometric functions: Value is regarded as radian (0..x*PI)
	sin	sine
	cos	cosine
	tan	tangent
	sinh	hyperbolic sine
	cosh	hyperbolic cosine
	tanh	hyperbolic tangent
	()	Brackets
Boolean algebra	Logical links: Variables will only be checked for the logical value '0'; if the value does not equal '0', it will be considered as '1'. As opposed to Bit formulas, the technical range of the Mathematics variables can be modified by a stretch factor (not equal '0' or '1').
	AND	logical 'AND'
	OR	logical 'OR'
	XOR	logical 'EXCLUSIVE OR'
	NOT	Negation
	()	Brackets
Statistics	The value is only available at the end of the calculation period (number of events).
	GltndMW	Moving average for changes
	GltndStdabw	moving deviation of changes
	Counters	counter function
	()	Brackets
Cross calculation
	Quer MW	Calculation of the average of several channels at the same time
	()	Brackets
Data reduction
	TMittelung	Average over time and events
	Sum	Sum over time and events
	Max	Maximum over time and events
	Min	Minimum over time and events
	Dif	Difference over time
	()	Brackets
Comparison
	<	less than
	>	greater than
	<=	Lower or equal
	>=	greater or equal
	<>	less or greater
	=	equal
	()	Brackets
Counting value processing	For linkages with time or event reference (statistics, data reduction) it is necessary to make additional entries. You can make them when ending the link.	only for SICAM 230!
