15.15.6.1 Operation accuracy
The accuracy of TEIGAPC depends on essentially three factors
• function cycle time
• the pulse length
• the number of pulses, that is, the number of rising and falling flank pairs
In principle, a shorter function cycle time, longer integrated time length or more pulses may lead
to reduced accuracy.
15.15.6.2 Memory storage
The value of the integrated elapsed time is retained in a non-volatile memory.

TEIGAPC
15.16 Comparator for integer inputs - INTCOMP
15.16.1 Identification
Function description
Comparison of integer values
15.16.2 Functionality
The function gives the possibility to monitor the level of integer values in the system relative to
each other or to a fixed value. It is a basic arithmetic function that can be used for monitoring,
supervision, interlocking and other logics.
