  The muon campus program at Fermilab includes the Mu2e experiment that will
search for a charged-lepton flavor violating processes where a negative muon
converts into an electron in the field of an aluminum nucleus, improving by
four orders of magnitude the search sensitivity reached so far. Mu2e's Trigger
and Data Acquisition System (TDAQ) uses otsdaq as its solution. Developed at
Fermilab, otsdaq uses the artdaq DAQ framework and art analysis framework,
under the-hood, for event transfer, filtering, and processing. otsdaq is an
online DAQ software suite with a focus on flexibility and scalability, while
providing a multi-user, web-based, interface accessible through the Chrome or
Firefox web browser. The detector Read Out Controller (ROC), from the tracker
and calorimeter, stream out zero-suppressed data continuously to the Data
Transfer Controller (DTC). Data is then read over the PCIe bus to a software
filter algorithm that selects events which are finally combined with the data
flux that comes froma Cosmic Ray Ve to System (CRV). A Detector Control System
(DCS) for monitoring, controlling, alarming, and archiving has been developed
using the Experimental Physics and Industrial Control System (EPICS) Open
Source Platform. The DCS System has also been itegrated into otsdaq. The
installation of the TDAQ and the DCS systems in the Mu2e building is planned
for 2021-2022, and a prototype has been built at Fermilab's Feynman Computing
Center. We report here on the developments and achievements of the integration
of Mu2e's DCS system into the online otsdaq software.
