integral unit
Unit associated with the integral gain.
This input accepts a ring or an array of rings.
| Name | Value | Description |
|---|---|---|
| Hz | 0 | Specifies that the integral gain is expressed in Hz. |
| s | 1 | Specifies that the integral gain is expressed in seconds. |
| min | 2 | Specifies that the integral gain is expressed in minutes. |
Default: The default value of this input changes depending on the data type you wire. If you wire a ring to this input, the default is s. If you wire an array of rings to this input, the default is Hz.
proportional unit
Unit associated with the proportional gain.
The relationship between the available units is K = 100/PB.
This input accepts a ring or an array of rings.
| Name | Value | Description |
|---|---|---|
| Gain (K) | 0 | Specifies that the proportional gain is expressed in terms of proportional gain (K). |
| Band (PB) | 1 | Specifies that the proportional gain is expressed in terms of proportional band (PB). |
Default: Gain (K)
proportional
Value of the proportional component of the controller.
This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.
integral
Value of the integral component of the controller.
This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.
action
Action of the controller.
This input accepts a ring or an array of rings.
| Name | Value | Description |
|---|---|---|
| Reverse | 0 | The controller is reverse-acting. |
| Direct | 1 | The controller is direct-acting. |
Default: Reverse
