Issue
Customers want to know the mapping of the QoS Diagnostics Data on CPUs and BMENOC0301/11 communication modules in M580 systems.

Product Line
Ecostruxure Control Expert, Unity Pro, M580, BMENOC0301, BMENOC0311

Environment
Control Expert v14.1, Windows 10 version 1902 (OS Build 18362.30), BMEP586040 v3.10, BMENOC0301 v2.17

Resolution
QoS Diagnostic data of 11 words, are availalble on CPUs and BMENOC0301/11 communication modules using Modbus function code 3 with the unit ID set to 100, offset Modbus Address 1275 and below is the MODBUS Register Mapping:

Address	MS Byte	LS Byte	CIP Type	Comments
1275	MS Byte	LS Byte	UINT	802.1Q Tag enable / disable
Offset + 01	MS Byte	LS Byte	UINT	DSCP PTP Event
Offset + 02	MS Byte	LS Byte	UINT	DSCP PTP General
Offset + 03	MS Byte	LS Byte	UINT	DSCP EIP Urgent
Offset + 04	MS Byte	LS Byte	UINT	DSCP EIP Scheduled
Offset + 05	MS Byte	LS Byte	UINT	DSCP EIP High
Offset + 06	MS Byte	LS Byte	UINT	DSCP EIP Low
Offset + 07	MS Byte	LS Byte	UINT	DSCP EIP Explicit
Offset + 08	MS Byte	LS Byte	UINT	DSCP Modbus IO Scanner (same as DSCP EIP High)
Offset + 09	MS Byte	LS Byte	UINT	DSCP Modbus Client/Server (same EIP Explicit)
Offset + 10	MS Byte	LS Byte	UINT	DSCP SNTP
