Areas of Expertise

Our engineers and programmers specialize in advanced PLC applications, particularly in the areas of high-speed or complex control.

The majority of our designs are based around the Allen Bradley or Siemens family of products, but we also work with Mitsubishi, Modicon, Toshiba, ABB and others.

Our team has been providing machine control panels and worldwide startup assistance to the two-piece metal container beverage can industry. for over 20 years.

Control spray timing directly from a ControlLogix PLC with an accuracy of ±0.02 msec.

MEG II Spray GunControl Technology has developed a high speed subroutine that accurately controls spray time to ±0.02 msec. Using an Allen-Bradley scheduled output module we have overcome the scan time limitations of the CPU. The information is downloaded to the module and it handles the precise timing, independent of the ControlLogix processor. All spray machine inputs and outputs are directly wired to the PLC and are available for customer use within the ladder logic program. The PLC output card can control either the Nordson or Sencon solenoid drivers.

The ControlLogix CPU is quite fast and can easily handle a high speed interrupt routine, but the fastest interrupt that can be used is typically 1.0 msec. or greater. Also creating processor delays are the housekeeping chores and high priority motion demands placed on the system.

Controls for the fabrication of thin-film solar panels

CIGS Control PanelControl Technology is working with Ascent Solar to produce solar cell power on thin flexible plastic. The process being used is called CIGS (copper-indium-gallium-diselenide) thin-film technology. CTI designed the control system for the first CIGS production line in 2006. The process was proven and CTI is now doing the CIGS controls for Ascent Solar’s 125,000 sq. ft. manufacturing facility in Thornton, Colorado.

CTI’s PLC based system controls the deposition of copper, indium, gallium and diselenide onto a high-temperature plastic substrate. The insulating features of the plastics make it possible to connect individual cells into modules during the process. These advances in CIGS processing significantly reduce the weight, cost, and complexity of photovoltaic products.
