This is ITER This is ITER

This is the ITER Agreement This is the ITER agreement. The project has been broken down in vertical slices which have been distributed to the ITER member states. There are 140 vertical slices and 80 of those includes instrumentation and control. 140 PA’s 80 include I&C

A bit of interface problems There are a lot of complex interfaces between all those vertical slices.

A bit of interface problems

Missing Items And then we have everything which was forgotten in the ITER agreement

The control system can help to fix this Our claim is that the control system can help to fix this. Why?

it identifies and may eliminate missing items It identifies and may eliminate missing items. Good examples are the missing instrumentation for vacuum vessel and thermal shields. This has been identified and corrective actions are now being taken.

Control system is horizontal and connects almost everything Because it is horizontal

it is involved in integration It integrates. It brings the vertical slices together again.

and is the primary tool for operation And it is the primary tool for operation and must therefore resolve all interface problems.

But this will work only if… …all these links work But this will only work if all these links work

That is why we, CODAC team, concentrate all our effort on standards (PCDH) and implementation of those standards (CODAC Core System) What is PCDH? Plant Control Design Handbook (PCDH) defines methodology, standards, specifications and interfaces applicable to all ITER plant systems I&C. PCDH is an annex to Project Requirements (PR) and applicable to all Procurement Arrangements with I&C. PCDH is released at regular interval throughout the construction phase of ITER. PCDH is reviewed by I&C IPT. On cost; Integration of compliant systems will be predictable and allow a tighter schedule. Receiving a multitude of black boxes will make integration completely unpredictable and therefore also the schedule. System compliant to standards will enable maintenance. As an experimental facility it is essential to be able to modify and improve systems with gained experience during operation. Only then can the full potential of ITER be explored. Standards also reduce the required number of spare parts as well as required amount of people supporting ITER.

Plant Operation Network

Plant System Host is an IO furnished hardware and software component installed in a Plant System I&C cubicle. There is one and only one PSH in a Plant System I&C. PSH is mainly used to interface the PS I&C with CODAC

Slow Controller is a Siemens Simatic S7 industrial automation Programmable Logic Controller (PLC). There may be zero, one or many Slow Controllers in a Plant System I&C. A Slow Controller runs software and plant specific logic programmed on Step 7 and interfaces to either PSH or a Fast Controller using IO furnished interface. A Slow Controller has normally I/O and IO supports a set of standard I/O modules. A Slow Controller has no interface to HPN. A Slow Controller synchronizes its time using NTP over PON. A Slow Controller can act as supervisor for other Slow Controllers.

Not relevant for PBS 43-62-63-65 Fast Controller is a dedicated industrial controller implemented in PCI family form factor and PCIe and Ethernet communication fabric. There may be zero, one or many Fast Controllers in a Plant System I&C. A Fast Controller runs RHEL and EPICS IOC. It acts as a channel access server and exposes process variables (PV) to PON. A Fast Controller has normally I/O and IO supports a set of standard I/O modules with associated EPICS drivers. A Fast Controller may have interface to High Performance Networks (HPN), i.e. SDN for plasma control and TCN for absolute time and programmed triggers and clocks. Fast Controllers involved in critical real-time runs a RT enabled (TBD) version of Linux on a separate core or CPU. A Fast Controller can have plant specific logic. A Fast Controller can act as supervisor for other Fast Controllers and/or Slow Controllers. The supervisor maintains Plant System Operating State. Not relevant for PBS 43-62-63-65

High Performance Computer are dedicated computers (multi core, GPU) running plasma control algorithms. Not relevant for PBS 43-62-63-65

High Performance Networks are physically dedicated networks to implement functions not achievable by the conventional Plant Operation Network. These functions are distributed real-time feedback control, high accuracy time synchronization and bulk video distribution. Not relevant for PBS 43-62-63-65

Simplest possible Plant System I&C – Data flow CODAC System / Mini-CODAC send commands and, if required, publish data from other Plant System I&C to PSH using channel access protocol PSH receives absolute time from TCN (4). The absolute time on the Slow Controller can be set using NTP with PSH as NTP server PSH publish data, alarms and logs to CODAC System / Mini-CODAC using channel access protocol. PSH and Slow Controller exchange data using standard interface provided by IO (3) The Slow Controller interfaces via signal interface to actuators and sensors and contains plant specific software and logic programmed on Step 7

Not relevant for PBS 43-62-63-65 Simple Mixed Plant System I&C – Data flow CODAC System / Mini-CODAC may send commands and, if required, publish data from other Plant System I&C to Fast Controller using channel access protocol (6). Fast Controller may publish data, alarms and logs to CODAC System / Mini-CODAC using channel access protocol (7) PSH supervises Fast Controller (8) to manage COS Not relevant for PBS 43-62-63-65 Fast Controller could interface directly to Slow Controller using standard interface provided by IO (9) or indirectly through PSH by (8) and (3) SD: Plant System I&C Architecture (32GEBH v2.3)

Not relevant for PBS 43-62-63-65 ITER fast controllers: I/O Bus and Industrial Form Factors PCDH defines CODAC selection for I/O bus: PCI bus (parallel) PCI-Express (serialized, PCI functions as payload) PCDH defines CODAC selection of communication method for interconnected systems: Ethernet The definition covers extremely large selection of different industrial computers and form factors CODAC Standards include and full support is given to: Conventional PCI and PCI Express boards PICMG 1.3 SHB industrial computers PXI Express hybrid chassis for PXI, CompactPCI and PXI Express I/O boards ATCA shelf and blades for high end data acquisition Not relevant for PBS 43-62-63-65 Question: VME and VPX systems are much better! Why you have selected the PCI bus, it if for office computers ! Answer: The CODAC team has experience and respect with the other bus standards. For better configuration management only one base standard needed to be chosen. The de-facto market dominance of the serialized PCI Express and Ethernet communication methods suggest long life time and good availability. Fast Controller Guideline document (referred later on) explains more about choices made. Fast Controllers for PCDH campaign

ITER I&C cubicles configurations Configuration1: The I/O interfaces of the I&C controllers are connected to PSEs through signal conditioning interfaces housed in an SCC. Configuration2: This configuration is similar to configuration 1, but LCC and SCC are merged in order to optimise the space allocation.

ITER I&C cubicles configurations Configuration3: In this configuration, the I&C controller of LCC is configured with a remote I/O rack installed in the SCC. The link between the LCC controller and the remote I/O rack may be fibre optic in the case of a long distance connection, strong EMI issues or any voltage isolation issue. Preferred configuration for Tokamak building. Configuration4: In this configuration, the PSE are connected to the I&C controller by a plant system I&C field-bus. The medium may be fibre optic. Targets for cubicle standardization: All LCCs and SCCs cubicles whatever the plant system.
