The integration of the instrument took place at the Astronomical Observatory of Geneva. It included the full tests of the Instrument Control Electronics (ICE) and Control Software, designed and developed at the INAF - Astronomical Observatory of Trieste. ESPRESSO is the first ESO-VLT permanent instrument whose electronics is based on Beckhoff PLCs. Two PLC CPUs shares all the workload of the ESPRESSO functions and communicates through the OPC-UA protocol with the VLT instrument control software. In this phase all the devices and subsystems of ESPRESSO are installed, connected together and verified, mimicking the final working conditions in Chile. This paper will summarize the features of the ESPRESSO control system, the tests performed during the integration in Europe and the main performances obtained before the integration of the whole instrument “on sky” in South America.ELETTRONICOenConference paper10.18429/JACoW-ICALEPCS2017-TUPHA195https://accelconf.web.cern.ch/icalepcs2017/FIS/05 - ASTRONOMIA E ASTROFISICA
