We upgraded the BPM data acquisition system of the PLS 2.5-Gev storage ring with the use of RFM (Reflective Memory). Our present BPM data acquisition system is based on EPICS VME IOC. It uses an analog-to-digital converter with 16-bit resolution and a 100-KHz conversion rate to digitize BPM raw electric signals. To get better position data from the digitized raw BPM data, we developed BPM data-averaging software utilizing RFM. With this averaging software, we could average 4000 samples of raw BPM data with the refresh rate of 2 seconds and get much better position data compared with the previous one. We installed data-averaging software and reflective memory modules into 12 local BPM IOCs for the routine operation. We are also planning to develop a fast global feedback system using RFM to improve beam quality in the near future.

The PLS SMS mobile system is based on Linux PC platform. The SMS mobile system is equipped with a wireless SMS(Simple Message Service) interface giving an opportunity to use fault alarm interlock system. It was developed as a network-based distributed real-time control system composed of several subsystems (EPICS IOC and PLC system). The mobile system sends simple message of fault trip signal to users’ mobile devices with fault tag address and immediately sends warning or alert messages to mobile devices, or remote users are real-time monitoring the device fault states by mobile devices. Control systems can be set remotely by mobile devices in emergency situation. In order to provide suitable actions against system fault, SMS Mobile System will enable system administrator to promptly access, monitor and control the system whenever users want and wherever users are, by utilizing wireless Internet and mobile devices. This paper presents the Mobile SMS system for PLS Control System.
