Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual

4.4 Internal Diagnostic Modbus Registers

There are a number of internal diagnostic registers that can be accessed via Modbus TCP/RTU that will help with analyzing and diagnosing the radio network. To access these register the Modbus Server will need to be enabled and a Modbus Server address will need to be configured (See 3.16 “Modbus I/O Transfer” for details on how this is done).

After enabling the Modbus Client you can then access the following information by reading the corresponding Modbus Address at the Server ID address.

Connection Information

Register	Module	Description
5000	Both	Total number Associated Stations
5001	Both	Current Radio Channel. See section 3.2 “Selecting a Channel” for channel details
5002	Both	Number Wireless Interfaces configured, includes Virtual Interfaces – wi1-wi10
5010	Both	Wireless Adaptor (wi0) - Link Status
5011	Both	Wireless Adaptor (wi0) - Link Status Inverted
5012	Both	Wireless Adaptor (wi0) - Number Associated Stations for this interface
5013	AP Only	Wireless Adaptor (wi0) - Points to the starting register of the AP's Station List. First
		interface (wi0) will always start at 5200 and dynamically enter data depending on the
		number of STA’s. Remaining interfaces (wi1-wi10) will be entered after wi0 data.
		Register 5023, 5033, etc. will indicate starting location for each interface.
5014	STA Only	Wireless Adaptor (wi0) – RSSI & BGND of Rx message from AP e.g. Hex 5F5D = 5F for
		RSSI and 5D for BGND (Convert value from hex to dec and add a “-“ e.g., 5F = -95dB)
5015	STA Only	Wireless Adaptor (wi0) - Transmit Data Rate from the Access Point
5016	STA Only	Wireless Adaptor (wi0) - MAC Address of the Access Point
5020-5026	As per 5010-5016 As per registers 5010-5016 but for the next Wireless Adaptor (wi1)
5030-5036	As per 5010-5016 As per registers 5010-5016 but for the next Wireless Adaptor (wi2)
5040-5046	As per 5010-5016 As per registers 5010-5016 but for the next Wireless Adaptor (wi3)
...etc.	As per 5010-5016 As per registers 5010-5016 but for the next Wireless Adaptor (wi10)
5200	AP Only	RSSI of the Client (STA)
5201	AP Only	Transmit Data Rate to Client (STA)
5202	AP Only	MAC address of Client (STA)
...etc.	AP Only	Dynamic list of STA's Refer to register 5023, 5033, etc. for starting register of each wi interface
9999	Both	Reset module (enter FFFF to reset module)
