==== PID control driver ==== ==== Configuration settings (center panel) ==== === Description === Single sensor input, single process variable output Adjustable process speed, P/I/D and polarity ---- ==== Configuration settings (center panel) ==== **Name** - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default "Field" name (if added to "Fields") **Active** Check box - Check this box and "Save changes" to run the driver. The driver program can be suspended by unchecking the box and clicking on "Save changes". **Notes** - This space can be used to store information specific to the device, such as: location, wiring, scaling, etc. ---- **Setpoint min / max** - Constrains the setpoint **Feedback sensor Field** - Drop down menu lists all configured Fields. Select one to be used as the feedback for the PID loop. **Feedback min / max** - Constrains the range of the value supplied by the feedback sensor's "Field". **Output (PV) Field** - Drop down menu lists all configured Fields. Select one to be used as the output for the PID loop. **Output min / max** - Constrains the signal sent to the output **Proportional (PV)** - Proportional factor **Integral (I)** - Integral factor **Derivative (D)** - Derivative factor **I-term min / max** - Constrains the cumulative effect of the "Integral" factor. **Update speed (seconds)** - Computation speed ==== Status & Registers (right panel) ==== ---- === Device Status === **Driver info** - Typically this is the name from the program file **Driver updated/version** - Date loaded or updated and the version of the driver **Battery & Signal** - Signal indicates the progress through the script. If driver fails to operate, signal number indicates progress **Driver status** - Color and text of status bubbles give a quick visual reference of Communication, Operation, and Application **Communication** - Com count indicates number of successful and unsuccessful data packets received ---- === Available registers === | 1 | Setpoint | | | 2 | Sensor (feedback) | | | 3 | Output (PV) | |
