Network Basics
Device ID
To route communication between devices, device identification numbers are
assigned to each device in a network.
In the SureCross system, device 0 is always the master device, the Gateway. All
other nodes are assigned device identification numbers from 1 through 15. Even
when all 15 nodes are not installed, the TDMA frame remains established for
15 nodes and the send and receive frames for those nodes are unused. Larger
networks may be set up with up to 128 nodes, establishing a much longer TDMA
frame.
Basic Wireless Network
In the most basic wireless network, input devices are wired to inputs on DX80
devices. The data created by the input device is transmitted to the specified output
on another device. A device wired to that output performs a task based on the
received data.
The simple wireless network shown illustrates a very basic wireless network
containing only two Node devices and a Gateway. More complicated wireless
networks might include multiple input and output devices wired to each Node and
several Nodes installed in the network.
In our simple example, the sensor wired to device 1 is an input device connected to
Node 1’s input. Data is transmitted to Node 2 and a device connected to Node 2’s
output performs a task - in this case the light turns on.
This standard wireless system with I/O is a simple network with no interfaces
to the outside world other than the I/O. To bridge the gap between the wireless
network and the outside world, the Gateway also functions as a Modbus 485 slave,
interfacing between two networks: the wireless network and a Modbus 485 network.
