Works-Bus ADC / DAC / DIO / Serial interface Power-supplies PVSS PLC S 7 (Vacuum) Chosen to avoid expensive hardware (VME) But: Unique development for ANKA Prevents integration of development from EPICS/TANGO community Failure rate of hardware increases! Exchange of hardware (PS) needed! New hardware with serial link (Ethernet) internal DAC/ADC Time to change!
