The programmable pCO controller lies at the heart of the ROX DDC control system. Configuration information for the PLC is stored and implemented on this controller. All field devices/units are controlled from this central point. Several controllers can communicate with each other by means of an internal bus system, which is also used to enable extensions or the central control of several plants. ROX control systems always operate according to the latest engineering standards and are optimised to ensure our plant operate with the best possible energy efficiency.As an option, data can also be recorded to enable analysis and optimisation of the plant even after commissioning.
