15.15.6.1 Operation accuracy
GUID-E0772193-9F6E-43DA-B642-2923565E5D4C v3
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
GUID-6FDD6590-30F9-4CC1-AC9D-945544AB8688 v3
The value of the integrated elapsed time is retained in a non-volatile memory.

15.16.2 Functionality
GUID-A93564FA-0017-4939-A9C1-095DA0FD9832 v1
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.
