Schneider Electric KNX The KNX counter interface Modbus REG-K is a gateway between a Modbus installation and the KNX bus. The device transmits measured power and consumption values from connected Modbus energy counters to the KNX bus. This data from the energy meters can be used to evaluate, visualize or reduce the energy consumption in your KNX installation. Up to 10 Modbus counters with RTU transmission protocol can be connected in parallel to the gateway. These counters send data via the gateway to the KNX. The gateway is always working in master mode, the connected Modbus devices work in slave mode. It is not possible to communicate KNX to the Modbus. The ETS application has pre-programmed templates for 17 different Schneider-Electric models of Modbus counters. Each connected Modbus counter can be assigned a corresponding template in the ETS. The corresponding Modbus registers are then assigned automatically to the communication objects on the KNX side. For Modbus devices without a template, up to 40 Modbus registers can be directly assigned to the communication objects on the KNX side. The device is powered via the KNX bus. With integrated bus coupler for mounting on TH35 DIN rail as per EN 60715. The bus connection is via a bus terminal.This text is machine translated.
