002668900 520__ $$9SISSA$$aIn 2017 the Large Hadron Collider at CERN has provided an astonishing 50 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV. The CMS detector has been able to record about 90\% of this data. During this period, the CMS electromagnetic calorimeter (ECAL), based on 75848 scintillating PbWO4 crystals and a silicon and lead preshower, has continued exhibiting excellent performance with a very stable data acquisition system. The ECAL DAQ system follows a modular and scalar schema: the crystals are divided in sectors, each of them controlled by 3 interconnected boards. These boards are responsible for the configuration and control of the front-end electronics, the generation of trigger primitives for the central CMS first level trigger, and the collection of data. A multi-machine distributed software configures the electronic boards and follows the life cycle of the acquisition process. The ECAL electronics modular configuration is reflected in the software where a tree control structure is applied. Through a master web application, the user controls the communication with the sub-applications that are responsible for the off-detector board configurations. Since the beginning of Run 2 in 2015, many improvements to the ECAL DAQ have been implemented to reduce occasional errors, as well as to mitigate single event upsets in the front-end electronics, and to improve the efficiency. Efforts at the software level have been made to introduce automatic recovery in case of errors. These procedures are mandatory to have a reliable and efficient acquisition system.
