LonWorks to Modbus RTU Serial Gateway

LonWorks to Modbus RTU Serial Gateway

Overview:

The Anybus Communicator LonWorks Gateway (ABC-LON-RTUslave) is a unique product that can bridge the communication gap with LonWorks networks and conventional Modbus RTU based systems & devices. The product can, via the PC-based configuration utility program ABC LWTool link data between devices located on a LonWorks Network and devices on a Modbus network. The LonWorks side of the product is fully compliant with the Lonworks network variables (SNVT's) and can be set up to produce or consume almost any network variable. The Modbus side of the product supports the classic Modbus registers for Input and Output data.

The Communicator Gateway supports RS232/422/485 on the serial side and Free Topology Network on the LonWorks side.

The Communicator is a SLAVE on the Modbus RTU side. This means that you connect this to a Modbus network which has a Master connected. The configuration of the module is simple and you can do it yourself with a configuration tool in Windows environment.

The delivery comes complete with a DSUB connector with screw terminals for the serial sub-network and a short Installation Leaflet for the electrical installation.

The configuration program ABC LWTool has to be ordered separately. A free demo is available for download.
