New approaches of operation with OPC data

Basic advantages of operation of SCADA systems with OPC data are outlined, and features and disadvantages of the existing data communication protocols are considered. The potential of this approach and available solutions are demonstrated using a new version of Iconics GENESIS32 V9 HMI/SCADA.


Real-time Operating Systems

Cheapening of industrial control system design by using adaptive decomposition of system resources

As the complexity and volume of codes increase, so does the probability of processor time shortage at the final stage of system development: the process of debugging and integration of the system becomes more sophisticated, and detection and removal of faults become more time-consuming and expensive. The risk that the processor resources will be spent on executing failure-inducing programs is eliminated by using a patented adaptive decomposition technology that assures real-time processor resource allocation between applications. Debugging expenses due to processor resource shortage are cut, and the final product becomes more reliable and protected and comes into the market faster.


PID controllers: design philosophy and modifications. Part 2

The article considers the philosophy of designing PID controllers, which have found wide application in process automation. Attention is also given to controllers for transport-delay systems, as well as to fuzzy and neuronet PID controllers.


Technique for testing the operation of Fastwel processor boards under QNX operating system

A technique for testing the compatibility of various versions of QNX operating system with application-specific Fastwel processor boards is described. The algorithms and scripts of test programs are presented. An example of stepwise assembling the image of QNX Momentics operating system and an embedded file system along with Photon graphic shell is given.
