7 Integrator (INT) Function Block
The Integrator (INT) function block integrates one or two variables over
time. The block compares the integrated or accumulated value to
pre-trip and trip limits and generates discrete output signals when the
limits are reached.
The Integrator function block supports mode control, demand reset, a
reset counter, and signal status calculation. There is no process alarm
detection in the block. Figure 7-1 illustrates the internal components of
the INT function block, and Table 7-1 lists the system parameters.
IN_1 = The first input value and status.
IN_2 = The second input value and status.
REV_FLOW1 = The discrete input that specifies
whether IN_1 is positive or negative.
REV_FLOW2 = The discrete input that specifies
whether IN_1 is positive or negative.
RESET_IN = The discrete input that resets the
integrator and holds reset until released.
OUT = The integration output value and
status.
OUT_PTRIP = A discrete value that is set when the
pre-trip limit value is reached.
OUT_TRIP = A discrete value that is set when the
trip target value (setpoint) is reached.
N_RESET = The number of times the integrator
function block is initialized or reset.
