A1.4 Integrator (IT) Block
the Integrator (It) block adds two main inputs and integrates them for output. the block compares the
integrated and accumulated value of totaL_SP and PRE_tRIP and generates discrete output signals.
out_tRIP or out_PtRIP when the limits are reached.
the output ia as represented by the following equation (for counting upward and rate conversion).
out.Value = Integration start value + total
total = total + Current Integral
Current Integral = (x + y) *∆t
x: In_1 value whose unit has been converted
A1.4.1 Schematic diagram of Integrator Block
the following shows the schematic diagram of the integrator block
Figure A2.1 Integrator block
In_1: Block input 1 (value and status)
In_2: Block input 2 (value and status)
REV_FLoW1: Indicates whether the sign of In_1 is reversed. It is a discrete signal.
REV_FLoW2: Indicates whether the sign of In_2 is reversed. It is a discrete signal.
RESEt_In: Resets the integrated values. It is a discrete signal.
RESEt_ConFIRM: Reset confirmation input. It is a discrete signal.
out: Block output (value and status)
out_PtRIP: Set if the target value exceeds
PRE_tRIP: It is a discrete signal
out_tRIP: Set if the target value exceeds
totaL_SP (or 0): It is a discrete signal.
the integration block is classified into the following five sections for each function:
• Input process section: Determines the input value status, converts the rate and accumulation, and deter-
mines the input flow direction.
• adder: adds the two inputs.
