Figure 196: 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.
