Modbus RS485
DB2-BRG
 |
Key features
|
The Bridge has the main function to connect through a ZigBee network one or more Modbus slave devices equipped with RS485 interface to one of the Gateways of the Digitron products family. In this way the PLC or PC-SCADA connected to the Gateway can communicate with Modbus slave devices eliminating wire installation. This channelis completely transparent.
Furthermore it can be a repeater and a parent device for battery powered sensors.
