A general control system of the Materials and Life science experimental Facility (MLF-GCS) consists of programmable logic controllers (PLCs), operator interfaces (OPI) of iFix, data servers, and so on. It is controlling various devices such as a mercury target and a personnel protection system. The present system has been working well but there are problems in view of maintenance and update because of poor flexibility of OS and version compatibility. To overcome the weakness of the system, we decided to replace it to an advanced system based on EPICS and CSS as a framework and OPI software, which has advantages of high scalability and usability. Then we built a prototype system, connected it to the current MLF-GCS, and examined its performance. As the result, the communication between the EPICS/CSS system and the PLCs was successfully implemented by mediating a Takebishi OPC server, true data of 7000 were stored with suitable speed and capacity in a new data storage server based on a PostgreSQL, and OPI functions of the CSS were verified. We concluded through these examinations that the EPICS/CSS system had function and performance specified to the advanced MLF-GCS.
