Gateway with W-Modbus- / W-BACnet module KYMASGARD® GW-WM Pro

The KYMASGARD® GW-WM gateway with W-Modbus/W-BACnet (Wireless), housed in an impact-resistant plastic enclosure with quick-release screws for surface mounting, serves as an interface between wired Modbus/BACnet and wireless W-Modbus/W-BACnet. Up to 100 devices can communicate with each other over long distances (up to 500 m in open space).
On the wired side, an electrically isolated RS485 transceiver is used (bus parameters adjustable via DIP switches).

The simple setup of the wireless network and the connection stability allow for easy expansion of wired systems with wireless W-Modbus/W-BACnet sensors. Even hybrid systems consisting of both wired and wireless devices can be easily integrated into existing network topologies via this gateway. Depending on the device type, two operating modes are available for this purpose:

Gateway mode (master function) serves as a base station for up to 100 wireless participants.
The connection is made on the wired side of an existing bus topology or directly to a DDC/PLC (Modbus/BACnet).

Node mode (adapter function) serves as a wireless adapter for 1 wired device. It is connected to the wired sensor and is used to link it to a wireless bus network (W-Modbus/W-BACnet). Node Pro mode (type 'GW-WM Pro') expands Node mode to support up to 16 wired devices.

Thanks to innovative parameterization of the RS485 interface and the elimination of wiring, the entire wireless network can be preconfigured (pairing devices, configuring the gateway). This allows the network to be quickly and easily installed and commissioned at the destination. In App Mode, the network setup can be verified and documented (PDF) using the Lumenradio W-Modbus app or the W-BACnet app (Apple/Android). Additional app features include installing firmware updates for the wireless module, changing device names, and detecting communication errors or duplicate addresses.
