1. A system for controlling and monitoring a reciprocal pump (110) producing hydrocarbons from a wellbore extending from the surface into the subterranean, the system comprising:

  • (A) a data gathering system to generate a signal representative of a surface operating characteristic of the pumping system;

    (B) a processor (130) in communication with the data gathering system, wherein the processor includes software that when executed utilizes the signal representative of the operating characteristic to determine a surface card, to determine a downhole card, and to generate a graphics signal (131) representative of at least one card of the surface card and the downhole card, and wherein the processor further comprises software that utilizes said least one card for generating a pump control signal (132); and

    (C) a permanently installed output system (140) at said processor and in communication with the processor, which upon receipt of the graphics signal from the processor provides a viewable graphical representation of said surface card and said downhole card on a regular and on-going basis as part of the normal operations of the system, wherein for the viewable graphical representation an axis on the surface card representing position is at a same scale as an axis on the downhole card representing position.
