Development of EPICS Channel Access Embedded ActiveX Components for GUI Development

The paper describes the integration of EPICS Channel Access protocol and Microsoft ActiveX technology towards developing a generalize operator interface (OPI) building facility for Windows platform. EPICS is used as the development architecture of the control system in Superconducting Cyclotron (SCC). Considering the operators' familiarity and compatibility with third party software, it was decided to use MS-Windows platform at operator interface level in SCC during commission. Microsoft Visual Basic (VB) is used on trial basis as OPI building platform to incorporate user specific features e.g. file system access for data storage and analysis, user authentication at OPI level etc. A set of EPICS Channel Access embedded ActiveX components is developed to ease the programming complexity and reduce developmental time of the OPI for Windows platform. OPIs, developed using these components and containing hundreds of process parameters, are being used reliably over a considerable period of time.

VECC, Kolkata, India

The performance evaluation and analysis of inter-system dependency of the various subsystems of the Superconducting Cyclotron demand a well configured data logging, archiving and historic analysis facility for massive number of control parameters along with on-line failure analysis facility of every system. EPICS is used as development architecture of the control system of these systems with MySQL used as database for large amount of relational data management. This combination requires integration between EPICS and MySQL server. For this purpose, MySQLArchiver as an EPICS Extension is developed for data logging and archiving of control parameters into MySQL database. This extension also provides a web based tool for online monitoring of control parameters and historic analysis of archived data. This paper describes the software architecture, implementations, as well as method of configuration for any other EPICS based control system as a utility. This facility is also elaborated with examples, web page views and experiences of deploying it in SCC.

The Cyclotrons at VECC, Kolkata i.e. Room Temperature Cyclotron (RTC) and Superconducting Cyclotron (SCC) comprise of internal and external beam diagnostic systems. These systems provide the beam developer with position, intensity, beam profile, a visual impression of the size & shape of ion beam, and operational control over diagnostic components like 3-finger probe, Beam Viewer probe, Deflector probe, Faraday cup, X-Y slit, Beam viewer etc. Automation of these components was initially done using customized modules for individual sub-system. An expansion of this facility and various levels of complexity demand modular design to cater easy modification and upgradation. The overall requirements are analysed and modular cards are developed based on basic functionalities like valve operation, probe/ slit/ viewer control, position read-out, interlock, aperture control of beam line and communication. A 32-bit Advanced RISC Machine (ARM) based card with embedded EPICS is chosen as the master controller and FPGA/ microcontroller is used for functional modules. The paper gives a comprehensive description of all modules and their integration with the control system.

The facility monitoring system of cyclotron operational parameters at VECC is developed and commissioned recently. Storage Area Network(SAN) is used to isolate the control LAN and office LAN which ensures secured access of the control systems from outside world. EPICS gateway service and modified channel access save/restore tool have been used to integrate EPICS based control system of VEC and SCC with office network. This paper describes the implementation details and operational experiences of the overall facility monitoring system.
