Integrator (INT) Function Block
21 REV_FLOW1 Indicates reverse flow when “true”;
0- Forward, 1- Reverse
22 REV_FLOW2 Indicates reverse flow when “true”;
0- Forward, 1- Reverse
23 RESET_IN Resets the totalizers
24 STOTAL Indicates the snapshot of OUT just before a reset
25 RTOTAL Indicates the totalization of “bad” or “bad” and
“uncertain” inputs, according to INTEG_OPTIONS.
26 SRTOTAL The snapshot of RTOTAL just before a reset
27 SSP The snapshot of TOTAL_SP
28 INTEG_TYPE Defines the type of counting (up or down) and the
type of resetting (demand or periodic)
29 INTEG_OPTIONS A bit string to configure the type of input (rate or
accumulative) used in each input, the flow direction
to be considered in the totalization, the status to be
considered in TOTAL and if the totalization residue
should be used in the next batch (only when
INTEG_TYPE=UP_AUTO or DN_AUTO).
30 CLOCK_PER Establishes the period for periodic reset, in hours.
31 PRE_TRIP Adjusts the amount of mass, volume or energy that
should set OUT_PTRIP when the integration
reaches (TOTAL_SP-PRE_TRIP) when counting up
of PRE_TRIP when counting down.
32 N_RESET Counts the number of resets. It can not be written or
reset.
33 PCT_INC Indicates the percentage of inputs with “good” status
compared to the ones with “bad or “uncertain” and
“bad” status.
34 GOOD_LIMIT Sets the limit for PCT_INC. Below this limit OUT
receives the status “good”
35 UNCERTAIN_LIMIT Sets the limit for PCT_INC. Below this limit OUT
receives the status “uncertain”
36 OP_CMD_INT Operator command RESET Resets the totalizer
37 OUTAGE_LIMIT The maximum tolerated duration for power failure
38 RESET_CONFIRM Momentary discrete value with can be written by a
host to enable further resets, if the option “Confirm
reset” in INTEG_OPTIONS is chosen.
39 UPDATE_EVT This alert is generated by any changes to the static
data.
40 BLOCK_ALM Used for all configuration, hardware, connection
failure, or system problems in the block. The cause
of the alert is entered in the subcode field. The first
alert to become active will set the active status in the
status parameter. As soon as the unreported status
is cleared by the alert reporting task other block
alerts may be reported without clearing the Active
status, if the subcode has changed.
