tAlarm and tWarning are possible to be defined with a resolution of 10 ms,
depending on the level of the defined values for the parameters.
The limit for the overflow supervision is fixed at 999999.9 seconds. The outputs
freeze if an overflow occurs.
13.13.6.1 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.
13.13.6.2 Memory storage
GUID-6FDD6590-30F9-4CC1-AC9D-945544AB8688 v3
The value of the integrated elapsed time is retained in a non-volatile memory.
