KNX Modbus RTU Gateway 886.1 secure
The device enables easy integration of Modbus devices that support the RTU protocol via RS-485 and can act as a Modbus master or slave. As Master the device can address up to 25 slave devices.
The assignment between KNX objects and Modbus registers can be configured via parameters in the ETS without an additional tool.
Two buttons and three multi-colored LEDs on the front panel allow local operation (synchronisation functions) and visualization of the device status.
The gateway provides a galvanic isolation between KNX bus and Modbus.
Power is supplied via the KNX bus. The device supports KNX Security.
Description
The KNX Modbus RTU Gateway 886.1 secure is supplied with power via the KNX bus and requires no additional auxiliary voltage.
Multiple downloads for communication tests are no longer necessary. The test requests are made directly via the gateway in the ETS, without the need for a USB RS-485 interface. This also works without KNX configuration, e.g: Group addresses directly during the first commissioning.
In this way, the settings can be tested before the ETS configuration..
