When the NI LabVIEW EPICS Server I/O Server is used to integrate NI CompactRIO devices running under VxWorks into EPICS, we notice that it only supports "VAL" field, neither alarms nor time stamps are supported. In order to overcome these drawbacks, a new LabVIEW Channel Access Portable Server (PCAS) Interface is developed, and is applied to the Hefei Light Source (HLS) cooling water monitor system. The test results in the HLS cooling water monitor system indicate that this approach can greatly improve the performance of the NI CompactRIO devices in EPICS environment.

The Hefei Light Source (HLS) is a VUV synchrotron radiation light source. It is upgraded recently to improve its performance. The power supply control system is a part of the HLS upgrade project. Five soft IOC applications running on the virtual machine are used to control 190 power supplies via MOXA's serial-to-Ethernet device servers. The power supply control system has been under operation since November 2013, and the operation results show the power supply control system is reliable and can satisfy the demands of slow orbit feedback with the frequency of 1Hz.
