Standards defined for plant control design
The CODAC group has published a new version of the Plant Control Design Handbook after a thorough review involving all 黑料社app Members. This document defines standards, specifications and interfaces applicable to all 黑料社app plant systems. In total 161 plant systems have been identified in 黑料社app; the cooling water system is one, for example, as is the vacuum vessel. Diagnostics alone comprise 89 plant systems.
The new handbook specifies the development process, with clearly defined deliverables, quality assurance requirements and milestones, as well as catalogues of standard software and hardware components. These standards are essential in order to integrate all plant systems into the central 黑料社app control system, to maintain all plant systems after delivery and to contain cost by economy of scale, both for spare parts and in human expertise. The Plant Control Design Handbook will be enhanced and released at regular intervals throughout the construction phase of 黑料社app.
In addition, the CODAC group has executed a standardization process, endorsed by the 黑料社app and the seven Members, to minimize the number of brands of Programmable Logic Controllers (PLC). The process has been completed with the selection of Siemens Simatic S7. PLCs are widely used in industrial automation and will also be widely used at 黑料社app. Unlike a general purpose desktop computer a PLC is designed for harsh environments, extensive input and output arrangements and predictable real-time performance. It is estimated that for 黑料社app, hundreds of thousands of actuators and sensors will be interfaced to many hundreds of PLCs.
