TABLE 7-1. Integrator Function Block System Parameters
Index Parameters Definition
1 ST_REV The revision level of the static data associated with
the function block.
2 TAG_DESC The user description of the intended application of
the block.
3 STRATEGY The strategy field can be used to identify grouping of
blocks. This data is not checked of processed by the
block.
4 ALERT_KEY The identification number of the plant unit. This
information may be used in the host for sorting
alarms.
5 MODE_BLK
6 BLOCK_ERR The summary of active error conditions associated
with the block. The block error for the Integrator
function block is Out of service.
7 TOTAL_SP The set point for a batch totalization.
8 OUT The block output value and status.
9 OUT_RANGE The high an low scale values, engineering units
code, and number of digits to the right of the decimal
point associated with OUT.
10 GRAND_DENY Options for controlling access of host computers and
local control panels to operating, tuning, and alarm
parameters of the block (not used by the device).
11 STATUS_OPTS Allows you to select option for status handling and
processing. The supported status option for the
Integrator block are: “Uncertain if Manual mode.”
12 IN_1 The block input value and status.
13 IN_2 The block input value and status.
14 OUT_TRIP The first discrete output.
15 OUT_PTRIP The second discrete output.
16 TIME_UNIT1 Converts the rate time, units in seconds.
17 TIME_UNIT2 Converts the rate time, units in seconds.
18 UNIT_CONV Factor to convert the engineering units of IN_2 into
the engineering units of IN_1.
19 PULSE_VAL1 Determines the mass, volume or energy per pulse.
20 PULSE_VAL2 Determines the mass, volume or energy per pulse.
