Traditional control systems used by competition are either proprietary embedded controllers or a “closed” HMI married with a PLC. Most HMI products force integrators to use their HMI software, thus limiting their capability. Enhancements and updates are usually slow to come, making it difficult to keep up with technology. On the control side, PLC’s have evolved very little over the years. Support for scripting and larger function libraries help, but developing advanced & adaptive control algorithms are difficult to impossible on most PLC platforms.
Products & Services
Human machine interface (HMI) software enables operators to manage industrial and process control machinery via a computer-based graphical user interface (GUI). The computer on which HMI software is installed is called a human machine interface or HMI.
HVAC controllers are used to monitor and control heating, ventilation and air conditioning (HVAC) systems in buildings. They monitor indoor environmental factors such as temperature and humidity, and control heating and cooling to maintain desired levels.
Vacuum controllers monitor and control vacuum levels for process equipment such as vacuum furnaces, autoclaves, and coating machines.
Mixing and blending controllers govern the ratio, mixing or blending parameters of two or more ingredients in a process. They are used to control the addition of gas or air, liquids, and/or solids.
Distributed and supervisory control systems (DCS / SCADA) are system architectures for process control applications.
