Details
The RS485 Extension can be used for long range cable based inter-stack communication. It uses the RS485 differential interface standard to achieve ranges of up to 1200m.
To establish a RS485 bus with Bricks, two RS485 Extensions and two Master Bricks are needed. Both Master Bricks can be connected to a full stack of Bricks and Bricklets, whereas one Master Brick is Battery powered and one is connected with USB. From a programming perspective the RS485 bus is completely transparent, i.e. the two stacks can be used exactly the same way as if they were both connected via USB.
It is also possible to create a bus with several RS485 Extension where only one is connected via USB (many-to-one routing).
Modbus RTU is used as the protocol on the RS485 interface. This allows to use a stack of Bricks and Bricklets with an RS485 Extension to be integrated in existing Modbus networks. It is also possible to communicate with a stack directly via Modbus from an embedded device or over a Modbus gateway.
