Data logging and archiving is an important task to identify and investigate malfunctions during storage ring operation. In order to enable a high-performance fault analysis, large amounts of data must be processed effectively. For this purpose a fundamental redesign of the present SQL database was necessary. The VME/VxWorks-driven CAN bus has been used for many years as the main field bus of the DELTA control system. Unfortunately, the corresponding CAN bus I/O modules were discontinued by the manufacturer. Thus, the CAN field bus is currently being replaced by a more up to date Modbus/TCP-IP communication (WAGO), which largely supersedes the VME/VxWorks layer. After hard- and software integration into the EPICS environment, several projects have been realized using this powerful field bus communication. The server migration to a 64-bit architecture was already carried out in the past. By now, all client programs and software tools have also been converted to 64-bit versions. In addition, the fast orbit feedback system project, using an in-house developed FPGA-based hardware, has been resumed. This report provides an overview of the developments and results of each project.
