mini-CIS The mini-CIS is an industrial computer, where the hardware and the software components are designed to perform the main functionality of the CIS and permit the FAT/SAT of Interlock Plant System.

Subsequent to the use of the mini-CIS, the integration of the corresponding PIS into the real CIS should be immediate and free from errors.

Interfaces data sheetThe functional interface data between the PLC and other plant Systems are documented and managed through the IDS (Interface Data Sheet)There are five categories of functional interfaces in the plant interlock controllers• Critical automatic data• CIS supervision on PIS• Critical manual data• Archiving interface• Maintenance interface.

Automatic generated Electrical diagramSEE Electrical expert.An electrical tool used by ITER exchanges information with PLC programming software in order to automatically generate and update Input/Output card layouts

Conclusions

The ITER Interlock System will most likely be the first machine protection system built with most of its components provided in-kind from up to 36 different countries

A strong effort is being put in place to ensure that all actors around the globe design, build and configure the parts of the puzzle to be properly integrated with the central

system

While a detailed design of the Central Interlock System has been already performed, a strategy has been put in place to continuously monitor the progressive growth the

overall interlock system.
