Ladder Logic Programming and PLC Simulation made Affordable


PLC Simulator PLCSIM, designed to assist in the teaching of ladder diagram Programming in a laboratory setting. Experienced with larger mechanical integration projects, such as palletizers, pick and place Robots conveyors and other material handling equipment; but most of the custom control engineering business comes from logical control systems. There are many system integrators out there that can do a good job building an electrical control panel. The panel is the part of the system that is seen, but it is only a small part of the system. The real quality of the system is the design, the operator interface and the pc or PLC programming that drives it.

CONTROLLER design PROCEDURE
Designing any controller from the family of PID algorithms entails the following steps:

  • specifying the design level of operation,
  • collecting dynamic process data as near as practical to this design level,
  • fitting a first order plus dead time (FOPDT) model to the process data, and
    • using the resulting model parameters in a correlation to obtain initial controller tuning values.

The collection and analysis of dynamic process data are critical steps in controller design and tuning. A “good” set of data contains controller output to measured process variable data that is descriptive of the dynamic character of the process. Suppose a controller output change forces a dynamic response in a process, but the data file only shows the tail end of the response without showing the actual controller output change that caused the dynamics in the first place. When generating dynamic process data, it is important that the change in controller output cause a response in the process that clearly dominates the measurement noise. It is important that the modeling tool display a plot that shows the model fit on top of the data. If the two lines don't look similar, then the model fit is suspect.
