Measures the performance of a control system by calculating the integral of the controller error.
Error of the controller.
This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.
This input changes to error signal when the data type is a waveform or a cluster of two arrays.
Default: 0
Error signal of the controller.
This input accepts a waveform or a cluster of two arrays.
This input changes to error when the data type is a double-precision floating-point number or an array of double-precision floating-point numbers.

Default: Integral Error (IE)
Loop-cycle time, or interval in seconds, at which this node is called.
If dt is less than or equal to zero, this node uses an internal timer with a one millisecond resolution.
This input is available only if you wire a double-precision, floating-point number or an array of double-precision, floating-point numbers to error.
Default: -1
Calculated integral of the controller error.
