The ecos 5 system family comprises a range of devices for room automation for the BACnet/IP system bus. The ecos504/505 room automation station (AS) is a modular, freely programmable BACnet Building Controller (B-BC) for the automation of up to eight rooms or flexible room segments with the functions room climate, lighting and sunshading. The ecos504/505 as BACnet Building Controller (B-BC) can also be used as an individual AS for other
functions in building automation (ventilation system unit, decentral data preparation for devices on a BACnet MS/TP line, central control of multiple VAV boxes etc.). The powerful programming environment, SAUTER CASE Suite, and the available function libraries allow both standard tasks of room automation and complex projects with flexible room division, based on room segments, to be carried out efficiently. Room operating units of the ecoUnit series, remote ecoLink I/O modules and two EnOcean ecoMod580 wireless interfaces are connected to the ecos504/505 via RS-485 interfaces. A half-duplex, 2-wire, electrically isolated RS-485 interface (variant F0C1) with the Modbus protocol as client (Modbus/RTU and Modbus/ASCII) enables the integration of up to 247 Modbus devices (Modbus servers) such as multi-sensors, room operating units, energy meters (electricity, heat), intelligent actuators, communicative controllers etc.
