Abstract

FTU three-level slow control system has undergone several enhancements during its lifetime [1], involving essentially the supervisory and medium level, while the lower level is still mainly based on old Westinghouse Numalogic PLCs. The legacy PLC controlling the toroidal magnet flywheel generator, named MFG1, is now being replaced with a more modern Siemens Simatic S7 PLC, because of its versatility an the ability to be integrated via standard networking protocol. The upgrade to this family of Siemens PLCs, which in the meantime has been selected as standard by ITER CODAC, has made MFG1 slow control an ideal candidate to deploy ITER CODAC software technologies and architecture to a running plant in an operating tokamak environment. A project has thus been started to port MFG1 control to ITER CODAC I&C architecture using the software package CODAC Core System [2] to interface the PLC with the ITER standard systems for instrumentation and control, Plant System Host (PSH) and Mini- CODAC, developing dedicated HMI and realizing the communication layer between MFG1 plant system and FTU supervisor. This paper will give a full account of the project and will report the results that have been obtained up to now, focusing also on the definite advantages provided by a distributed control architecture compared to the supervisor-dependent one still running at FTU, in view of future fusion devices.
