ITER Plant Control Design Handbook (PCDH) defines standards, specifications and interfaces applicable to ITER plant system instrumentation and control (I&C). These standards are essential for ITER to:
  • Integrate all plant systems I&C into one integrated control system
  • Maintain all plant systems I&C after delivery acceptance
  • Contain cost by economy of scale (spare parts, expertise)

The new version of PCDH (version 7) issued in February 2013 is a final version which is supposed to be used to design and manufacture the production I&C systems for ITER. By publishing a full set of PCDH documentation together with regular releases of the CODAC Core System software ITER seeks to involve control systems community into testing and verification of ITER I&C standards in order to arrive to modern and robust control system suitable for ITER and for scientific installations around the world.

For a quick overview of the PCDH, please check the following presentation:
PCDH consists of a master document and satellite documents. The master document contains principal requirements to ITER plant system I&C; satellite documents, in turn, go deeper into details of various I&C subjects providing recommendations, guidelines and examples on how to apply the PCDH. While the core document is fixed, satellite documents may evolve with time to incorporate the latest project developments or manage obsolescence. In 2017 many annexes were checked for consistency and, where appropriate, updated to include the latest technical information available.
