Mechanizing in Real Time Factory Automation Systems Mechanizing in Real Time aeSolutions has delivered automation solutions with Programmable Logic Controllers for nearly two decades. In the 1970's, a PLC was a programmable emulator of relay ladder logic. Today, a PLC is a scaled down controller, often stand alone, but with much of the power and some of the functions of controllers used in DCS process automation. Multiple PLC's are often networked somewhat like a DCS with fewer features. aeSolutions can provide the right PLC automation system when a client needs highly reliable and very fast real time response to events in a manufacturing cell or an electromechanical panel. Ruggedized operator displays and touch screens allow local HMI control. The PLC can also be interfaced to a supervising DCS. • High speed I/O and processing • Ruggedized environment • Basic networking and communications • Ladder logic programming familiar to I&E staff • Scalable in size and cost Automation Services Previous Next

Enlisting More Variables Advanced Regulatory Control - ARC Enlisting More Variables aeSolutions process control specialists solve problems with Advanced Regulatory Control (ARC) when single variable PID control is not adequate. Cascade, feed forward, ratio, Smith predictor, and override controls are standard methods to include an additional process variable in PID loops to compensate for process dead time, or non-linearity. Multivariable and model-based controls are employed for more complex process automation challenges encountered in chemical plants and refineries. aeSolutions helps the client's process engineers take advantage of the multivariable control capabilities found in the latest generation of DCS systems. These offer real time performance with multivariable models available at the controller's function library level. Automation Services Previous Next

Approving the Configurations Simulation and Factory Acceptance Testing Approving the Configurations aeSolutions builds process simulation test beds to prove that controls and operator interfaces will function in accordance with project requirements. A FAT plan with checklists lets the client's representatives test every loop and HMI screen against the software design specifications. Quality of workmanship can be reviewed. Punch list items are resolved before shipping the system. aeSolutions offers multiple options for FAT simulation: Option 1. Simulation panels hardwired to the real system I/O cards to emulate field devices. Option 2. Simulation logic configured in the real controllers while ignoring real I/O racks. Option 3. Simulation computers that interface to the real controller's I/O bus in place of the real I/O racks Option 4. Simulation platforms that emulate the real controllers and I/O (for testing logic configurations without controller hardware). Automation Services Previous Next
