The CPPF Concentration Pre-Processing and Fan-out (CPPF) system is one of the electronic subsystems of the upgraded Compact Muon Solenoid (CMS) Level-1 trigger system. It includes, in hardware, eight specially designed CPPF cards, one CMS card called AMC13, one commercial Micro-TCA Carrier HUB (MCH) card, and a Micro-TCA shelf. Powerful online software is needed for the system, including providing reliable configuration and monitoring for the hardware, and a graphical interface for executing all actions and publishing monitoring messages. Further, to control and monitor the large amount of homogeneous hardware, the SoftWare Automating conTrol Hardware (SWATCH) concept was proposed and developed. The SWATCH provides a generic structure and is flexible for customization. The structure includes a hardware access library (HAL) based on the IPbus protocol, which assumes a virtual 32-bit address/32-bit data bus and builds a simple hardware access layer. Furthermore, the structure provides a graphical user interface, which is based on modern web technology, and is accessible by web page. The CPPF controlling and monitoring online software was also customized from a common SWATCH cell, and provides a finite state machine (FSM) for configuring the entire CPPF hardware, and five monitoring objects for periodically collecting monitoring data from five main functional modules in the CPPF hardware. This paper introduces the details of the CPPF SWATCH cell development.
