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

• (combinable with other areas)
• (combinable with other areas)
• (combinable with other areas)
• (not combinable)
• (not combinable)
• (not combinable)
• (combinable with other areas)
• (only SICAM 230)

Trigonometry

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

sin

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).

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.
