A5.6.3 Reset Process
The basic reset process sequence is as follows:
1. Snapshot
2. Clearing the integrated values
3. Reset count increment
4. Judging OUT_TRIP and OUT_PTRIP
1. Snapshot
Saves the following values in the specied
parameters before clearing the integrated values.
These values will be retained until the next reset is
made.
STOTAL = Total
SRTOTAL = RTotal
SSP = TOTAL_SP
2. Clearing the integrated values
The reset process clears the Total, ATotal, and
RTotal values in the internal registers.
Total = 0
ATotal = 0
RTotal = 0
3. Reset count increment
Each time a reset is made, the N_RESET
parameter will be incremented.
The high limit is 999,999, and if this limit is
exceeded, the count returns to “0.”
4. Judging OUT_TRIP and OUT_PTRIP
OUT_TRIP and OUT_PTRIP are judged again on
the basis of the cleared integrated values. Read
APPENDIX 5.5 “Output Process”
There are three options relating to a reset:
i Conrm reset (bit 8 of INTEG_OPTS)
ii Carry (bit 6 of INTEG_OPTS)
iii Generate reset event (bit 9 of INTEG_
OPTS)
i Conrm reset (bit 8 of INTEG_OPTS)
If this option is enabled, the next reset is rejected
until “1” is set to RESET_CONFIRM.
ii Carry (bit 6 of INTEG_OPTS)
If this option is enabled while INTEG_TYPE is
UP_AUTO or DN_AUTO, the value exceeding
the threshold at a reset will be carried into the
next integration.
If INTEG_TYPE is any setting other than UP_
AUTO or DN_AUTO, this option is irrelevant.
iii Generate reset event (bit 9 of INTEG_OPTS)
If this option is enabled, an alert event is
generated if a reset occurs.
