Abstract: There are eight RF power sources for linac accelerator of China Spallation Neutron Source phase-I project, and each RF power source was controlled by one digital low level RF unit separately. The local control of digital low level RF is a non-EPICS system, which could not directly communicate with EPICS clients. Remote control of the low level RF local control system by EPICS clients is realized by embedding a C# type EPICS server to the upper control application, thus the low level RF local control was ported into the EPICS framework. Since its online deployment for linac low level RF control, the remote control system has been stable and reliable in operation.
