New features in the SDDS-compliant epics toolkit

This paper introduces new features and programs developed to enhance various aspects of the SDDS-compliant EPICS toolkit. A new optimization program, sddsoptimize, was added to the toolkit; it employs the Simplex and 1-D scan methods and can be used for both EPICS and non-EPICS optimizations. Several new data logging programs were also developed, including a new, more flexible glitch logger that logs data before and after a glitch occurs. Another new data logger logs data every time the value of a process variable changes. With the data generated from this program, it is now possible to restore settings from any arbitrary time without the need for a snapshot of the system. Another new addition is the capability of saving and restoring waveform process variables. In addition to these new features, performance improvements have been realized in all the toolkit programs by replacing EZCA calls with low-level channel-access calls. Some of the toolkit programs have been upgraded to run on vxWorks to achieve higher performance
