Resolution
Identity data of 24 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 2001 and below is the MODBUS Register Mapping:

Address	MS Byte	LS Byte	CIP Type	Comments
2001	MS Byte	LS Byte	UINT	Vendor ID
Offset + 01	MS Byte	LS Byte	UINT	Device Type
Offset + 02	MS Byte	LS Byte	UINT	Product code
Offset + 03	MS Byte	LS Byte	USINT	Revision – Major Revision
