GM International explosion-proof automation systems
Multiplexing systems considerably simplify the data acquisition tasks in circumstances where hundreds and thousands of points need to be surveyed, thereby saving miles of hard wire and hundreds of hours of commissioning. The systems offer a number of advantages over traditional solutions, and such benefits become more visible when it comes to using the systems in hazardous areas. The article covers two of GMI’s solutions for explosive facilities.
Use of VARISTAR cabinet platform at ALBA CELLS Synchrotron Light Facility
The article provides an example of cost-effective approach when building a reliable distributed control system for a sophisticated engineering-technical complex at ALBA Synchrotron Light Facility. The use of unified cabinet platforms, choice of CompactPCI, industrial computers and Ethernet as fieldbus contributed significantly to solving the cost optimization task while maintaining a high level of functionality and safety.
Use of the resolvers in distributed automatic control system of a big azimuthal telescope
The article discusses the initial requirements for upgrade of the control system of a big azimuthal telescope and replacement of the centralized control scheme with a distributed network architecture of the automatic control system. Also included is a description of the ways to solve some real-time problems which occur in the distributed control system due to the instability of delays in asynchronous data transfer from the telescope resolvers to the control software.
Topology with foresight: data transmission via Ethernet in the process industry
Until now, the opportunities to use PCs or remote solutions in the process industry were extremely limited for technical reasons. One of the interesting alternatives to the solutions used to date is to transfer data via Ethernet. Unlike classic visualization concepts, the maximum transfer distances are greater and the topology is simpler and more flexible because the visualization platform becomes just another normal network component.
Automation of geographically distributed objects using MicroPC
The article suggests solutions on geographically distributed objects automation with signal transmission between the devices via radio channel and message generation according to IEC 870 series standards. These solutions are implemented using MicroPC hardware.
