TEIGGIO Simplified logic
TEIGGIO main functionalities are
•
integrate the elapsed time when IN has been high
•
applicable to long time integration (≤999 999.9 seconds)
•
output ACCTIME presents integrated value in seconds to all tools
•
integrated value is retained in non-volatile memory, if any warning, alarm or
overflow occurs
•
any retained value with a warning/alarm/overflow shall be available as the
initiation value for the integration followed by a restart.
•
RESET: Reset the integration value. Consequently all other outputs are also reset
•
unconditionally on the input IN value
•
reset the value of the non-volatile memory to zero.
•
BLOCK: Freeze the integration and block/reset the other outputs
•
unconditionally on the signal value
•
BLOCK request overrides RESET request.
•
Monitor and report the conditions of limit transgression
•
overflow if output ACCTIME >
tOverflow
•
alarm if ACCTIME >
tAlarm
•
warning if ACCTIME >
tWarning
.
The ACCTIME output represents the integrated time in seconds while
tOverflow
,
tAlarm
and
tWarning
are the time limit parameters in seconds.
