With the new BC9191-0100 room controller, Beckhoff has extended its range of compact devices for room automation toward larger application programs and simplified communication to other units via bus systems. The controller has an integrated PLC and the sensor/actuator interfaces necessary for room automation. As a result, the BC9191-0100 can be used as an autonomous or local controller. Furthermore, it integrates an RS-485 sub-interface in order to connect room control units via serial protocols such as Modbus RTU. Communication is simply parameterised via the Modbus library included in the range of functions of TwinCAT automation software from Beckhoff.
The BC9191 room controller integrates various automation functions in a single module, representing a compact and efficient solution for room control. Pre-installed standard functionalities cover all necessary functions, simplifying commissioning. Extensions or changes to the room automation functions are possible in the TwinCAT development environment and save on the complex re-wiring that would normally be the case with wired controllers.
With 128 Kbyte of memory, the controller offers extended memory capacity, which enables the creation of more complex user programs. Communication with the room control units takes place predominantly via the Modbus RTU protocol. However, devices with freely definable serial protocols, such as weather stations, can also be connected via the RS-485 interface.
The BC9191 has two switched Ethernet interfaces for integration into the higher-level Ethernet network and integrates three digital inputs, eg, for the integration of window contacts or occupancy sensors. The sensor systems for air quality and room brightness can be connected via three analog 0-10 V inputs. Temperature measurement takes place via a PT/Ni1000 input and is supplemented by resistance measurement for setting the setpoint value. Six relay or Triac outputs, 230 VAC, can control peripherals such as air heaters and fans. Two analog 0-10 V outputs can be used to control volumetric air flow or similar functions.
