Note the following important information:
• For every device, 30 registers are reserved. All new devices joining the network
are allocated registers in ascending order.
• Devices are assigned registers in the order they join the WirelessHART net-
work.
• Gateway supports function code 3 and holding registers only.
• Modbus ID (a.k.a Slave ID) of the gateway is fixed to 255.
