+ 
Addition

Trigonometry 
Trigonometric functions: Value is regarded as radian (0..x*PI) 


sin 
sine 

cos 
cosine 

tan 
tangent 

sinh 
hyperbolic sine 

cosh 
hyperbolic cosine 

tanh

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

Statistics 
The value is only available at the end of the calculation period (number of events).

Moving average for changes 

GltndStdabw 
moving deviation of changes

Sum 
Sum over time and events 

Max

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.
