| THPHA155 | PLC Integration in EPICS Environment: Comparison Between OPC Server and Direct Driver Solutions | 1767 |
|

|
In the IFMIF EVEDA project*, INFN-LNL Laboratory has been involved in the design and construction of a normal conducting Radio Frequency Quadrupole (RFQ) used to bunch and accelerate a 130 mA steady beam to 5 MeV. The EPICS based control system** has been entirely developed in house using different hardware solutions: PLC for tasks where security is the most critical feature, VME system where the acquisition speed rate is crucial, common hardware when only integration is required without any particular feature in terms of security. Integration of PLCs into EPICS environment was originally accomplished through OPC DA server*** hosted by a Windows embedded industrial PC. Due to the issues analyzed in injector LCS, LNL proposed to migrate to the usage of EPICS Direct Driver solution based on s7plc****. The driver itself is suitable for direct communication between EPICS and PLCs, but it doesn't take care of data update and synchronization in case of communication failure. As consequence LNL team designed a dedicated method based on state machine to manage and verify data integrity between the two environments, also in case of connection lost or failure.

| THPHA157 | IFMIF EVEDA RFQ Local Control System Integration into Main Control System | 1771 |
|
||
|
The RFQ apparatus Local Control System built for IFMIF EVEDA Project* has been designed and realized for being both a standalone architecture and part of a more complex control system composed by different sub-systems. This approach let RFQ's engineers and scientists have a degree of freedom during power tests in Legnaro and during the RFQ integration in IFMIF EVEDA facility in Rokkasho. In this paper we will describe the different aspects observed when the LCS was converted from the standalone configuration to the final integrated one.
