Modbus RTU with Multiple Slave Devices
In the host controlled configuration shown below, the Gateway is a Modbus slave to the host system, but remains the master of the wireless
network. The Gateway is connected directly to the host system using a field bus connection. This system also connects DX85 Expanded I/O
devices and a third-party Modbus slave device to the serial bus to expand the available I/O. The DX80 Gateway and each DX85 connected as
shown below are Modbus slave devices to the host system.
Purpose: This wireless network collects I/O
data and sends it back to a Modbus host
system, but adds local wired I/O points and
expands the network using field bus.
