4. CONFIGURATION
FAIL_TOT:
This is the parameter which defines the fail safe mode
of the Totalizer block. This parameter determines the
operation of the Totalizer block during the occurrence
of input values with bas status.
1 0: RUN UNCERTAIN: Non Specific, ok
2 1: HOLD UNCERTAIN: Last Usable Value, const.
3 2: MEMORY UNCERTAIN: Non Specific, ok
Note: Suppose that SET_TOT = TOTALIZE, MODE_TOT ≠ HOLD.
FAIL_TOT value TOTAL Status
T0410.EPS
MODE_TOT:
This is the parameter which defines the direction of the
totalization.
0: BALANCED; True arithmetic integration of the
incoming rate values.
1: POS_ONLY; Totalization of positive incoming rate
values only.
2: NEG_ONLY; Totalization of negative incoming rate
values only.
3: HOLD; Totalization stopped.
SET_TOT:
SET_TOT is the parameter in order to assign the
condition to the Totalizer.
0: TOTAILIZE; “Normal” operation of the Totalizer.
1: RESET; Assign value “0” to Totalizer.
2: PRESET; Assign value of PRESET_TOT to
Totalizer.
PRESET_TOT:
This is the parameters in order to define the starting
value to the Totalizer.
TOTAL:
This parameter contains the integrated quantity of the
rate parameter provided by CHANNEL and the
associated status.
The alarm information that a priority is the highest is
set as status.
In case of two or more alarms belonging to the same
sub status are generated, the priority of alarm is so
high that the number of an alarm message is small.
However, as for O/S Mode alarm of Totalizer block
and Physical Block, a priority becomes high most.
