Abstract The Belle II e⁺/e⁻ collider experiment at KEK will include a new pixelated detector (PXD) based on DEPFET technology as the innermost layer. This detector requires a complex control and readout infrastructure consisting of several ASICs and FPGA boards. This paper present the architecture and EPICS-based implementation of the control, alarm, and interlock systems, their interface to the various subsystems, and to the NSM2-based Belle II run-control. The complex startup sequence is orchestrated by a statemachine. CSS is used to implement the user interface. The alarm system uses CSS/BEAST, and is designed to minimize spurious alarms. The interlock system consists of two main parts: a hardware-based system that triggers on adverse environmental (temperature, humidity, radiation) conditions, and a software-based system. Strict monitoring including the use of heartbeats ensures permanent protection and fast reaction times. Especially the power supply system is monitored for malfunctions, and all user inputs are verified before they are sent to the hardware. The control system also incorporates archiving, logging, and reporting in a uniform workflow for the ease of daily operation.
