Abstract
A process control network arrangement comprising: a sensor to provide signals that correspond to the actual value of a process variable to be controlled; first circuit means including adjustable resistance means, and connected to the sensor and corresponding to the lines from or to produce a predetermined variable speed response on said network; means for providing a signal corresponding to a predetermined value of the variable to be controlled; means for adding the signal mentioned last and the sensor's line to provide a signal corresponding to the difference between them; variable gain means for varying the gain of the difference signal; and second circuit means including adjustable resistance means, and connoted to the variable gain means and responsive to the adjusted gain signals to produce a predetermined variable integral response on said network.
