  A high-performance time-of-flight (TOF) MRPC wall is being built for the CBM
experiment at FAIR for charged hadron identification. The detector control
system for the TOF system will be based on EPICS. All components like power
supplies for low and high voltages, power distribution boxes, gas control and
front-end electronics (FEE) are controlled and monitored. In a test, called
mini-CBM, all these functionalities are implemented and tested. For monitoring
the detector environment and the status of the front-end electronics, a slow
control application is implemented based on IPbus, which is an FPGA-based slow
control bus used for the TOF data acquisition system. In addition to the
functions of control and monitoring, exception handling and data archiving
services are implemented as well. This system has been fully verified in beam
tests in 2019 at GSI.
