This overview of the Control, Data Acquisition, and Communication system (CODAC) at the COMPASS tokamak includes the hardware set-up, software implementation, and communication tools. The diagnostics and the data acquisition are tailored for high spatial and temporal resolution required by the COMPASS physics programme, which aims namely at studies of the plasma edge, pedestal, and Scrape-off-Layer (SOL). Studies of instabilities and turbulence are also an integral part of the programme. Therefore, the data acquisition consists of more than 1000 channels, sampled at rates from 500 kS/s up to 2 GS/s. Presently, the feedback system controls the plasma position and shape, plasma current, and density. The feedback control runs within the Multi-threaded Application Real-Time executor (MARTe) framework with two threads, a 500 microseconds cycle to control slow systems and a 50 microseconds cycle to control the fast feedback power supplies for plasma position control.
