  4. Motivation M M M Protection system: Monitoring + Actuators If Monitoring detects a fault: Actuators switch off system 1 single link is not reliable enough. 2 redundant links provide required safety ITER Magnets offer a different challenge: Maximize availability Minimize fast discharges Therefore, study of other architectures (2oo2,1oo3, 2oo3, etc).

  7. DLIB: Purpose • Roles: • Simple interface for user signals with the 2oo3 discharge loops. • Transmit fast discharge requests to different users. • Galvanic Isolation between Users and PLC. • Unique way of dealing with client diversity (ie. different interlocks systems, electronics, voltages…). • Independent of upgrades at the user side. • Responds to required dependability and provides safe and reliable interlocking in both directions. • Simplified test and commissioning (common diagnostics and monitoring). • Remote test facility as from the level of the client connection.

  10. DLIB: from USERS to Interface • Users send status through 3 independent Current Loops. • Current limited by the interface box (fixed current source). • Design used at CERN with success (more than 220 similar interface boxes in use). • 2oo3 Logic opens discharge loop.

  12. DLIB: from Interface to USERS • Transmit to user the status of the discharge loop links. • 1 to 1 because of dependability requirements. • Users MUST make the 2oo3 evaluation of the signals. • Optocoupler acting as dry contact and galvanic isolation with the User

  14. DLIB: Test and Monitoring • The Prototype V1 Interfaces had a Profibus slave. • V2 uses PROFINET with a new ASIC called TPS-1. • 16 bits of data in each direction. • Status of discharge loop, clients and extra info (temp, use of 2oo3 logic, configuration…). • Managed by FPGA, Actel ProASIC3. • Due to time stamping limitations of this solution, and the availability of a new chip, Prototype V2 uses a ITER compliant solution based on Profinet (Industrial Ethernet based Fieldbus).

  16. DLIB: Connectors • Use compact and fully enclosed mechanics. • BURNDY connectors offer good EMC and dependability. • 8 and 12 pins, male and female, to avoid misconnections. • Diagnostics port in front panel for monitoring with Profinet. [11] 16

  18. Experience from first Prototype • The first prototype was assembled and tested thoroughly. • Small test board with switches and LEDs to simulate the discharge loop and the users (at 24 V and 5 V). • Everything “analogue” works according to specifications. • Profibus link has been tested successfully as well. • Integration and tests with PLC were done by M. Zaera in Valencia. • A first version is installed at ITER since October for the HTS current leads tests. This will serve as a real test of the devices and architecture. • PLC + 2 DLInterface Boxes configured with 1oo2 Logic. • It “survived” a Preliminary Design Review at ITER. [11] 18

  20. SecondPrototype • Design is finished and we manufactured 5 units that are working and ready for use. • The analogue part and interfaces with discharge loop and clients remain mainly unchanged except for small tweaks. • The functionality it’s the same. It can work together with a first prototype. • Main difference is the use of Profinetinstead of Profibusfor monitoring. • A brand new chip, TPS-1 from Renesas is used to manage the Profinet stack. • As it’s Ethernet based: substitution of the frontal DB-9 connector for 2 RJ-45 ports. • Allows precisetimestamping of 1ms or less. (to be tested yet) • Much easier and faster to implement from the PLC point of view. • 4 devices will be taken to ITER next week andsent to the different clients for early testing of the interface.

  22. Profinet Profinet offers several advantages over Profibus:

  23. TPS-1 This brand new chip is in charge of the Profinet stack. 196 pins 1mm pitch BGA package + 2 Fast Ethernet ports. Documentation has been quite a challenge (missing information). A lot of emails exchanged with support and several surprises. Frist time programming of the chip is tedious. But then it works incredibly well. Next Steps: Try the Isochronous Real Time mode (to achieve 1 ms sync) Test with a Siemens PLC and play around with this synchronization options.
