Description

In the beam diagnostics system of the CSNS accelerator, multiple National Instruments (NI) PXIe multifunction DAQ modules were utilized for readout system development. The original software architecture, implemented with LabVIEW+DSC modules on Windows system, introduced substantial challenges in EPICS integration. This paper details a software upgrade methodology that preserves the existing NI PXIe hardware infrastructure. The upgraded system implements standard EPICS Input/Output Controllers (IOCs) developed in C language under Linux system, integrating signal acquisition and front-end electronics control functionalities within EPICS IOCs. This re-engineering approach enhances the readout system stability while improving the reliability and flexibility of EPICS data interaction. The successful migration demonstrates an effective hardware-preserving software optimization strategy for accelerator instrumentation systems.
