Emerson 0471-0128-02 CoE communication area, Definitions, Device type object, Identity object

Definitions:

•<index> : A signed 16-bit number. This is the index of the object dictionary entry specified in four hexadecimal characters.

•<access> : A value describing how the object may be accessed (RW = read/ write, RO = read-only and WO = write-only).

•<size> : The size of the object/sub-index in bytes.

•<unit> : The physical unit (e.g. ms, counts per second etc.).

6.1.1CoE communication area

The first set of objects specify general communication settings.

Table 6.4 Device type object

0x1000	Device type
Access: RO		Range: N/A	Size: 4 bytes	Unit: N/A
Default:	0x00030192
Description:	The primary CoE functional profile is DSP-402, the value of the object is defined as follows:
	Bits 0 to 15 (Device profile number): 402 (0x192)
	Bit 16 (Frequency converter): x
	Bit 17 (Servo drive): y
	Bit 18 (Stepper motor): 0
	Bit 24 (DC drive - manufacturer specific : z
	Bits 25 to 31 (Manufacturer specific): 0
	This value will depend on the drive operating mode and/or type. On a Unidrive SP in open-
	loop or closed-loop mode or a Mentor MP in closed-loop mode, bit 16 will be set, while bits
	17 and 24 will be cleared. On a Unidrive SP in Servo mode or a Digitax ST, bit 17 will be
	set, while bits 16 and 24 will be cleared.
Table 6.5 Identity object
0x1018	Identity object
Sub-index 0
Access: RO		Range: N/A	Size: 1 byte	Unit: N/A
Default:	4
Description:	The number of the last sub-index in this object.
Sub-index 1
Access: RO		Range: N/A	Size: 4 bytes	Unit: N/A
Default:	0x000000F9
Description:	This contains the EtherCAT Technology Group vendor ID for Control Techniques
	(0x000000F9).
Sub-index 2
Access: RO		Range: N/A	Size: 4 bytes	Unit: N/A
Default:	See Pr MM.01.
Description:	This has the value of the option ID code.
Sub-index 3
Access: RO		Range: N/A	Size: 4 bytes	Unit: N/A
Default:	High word: Pr MM.02. Low word: Pr MM.51.
Description:	Contains the option module software version number (the major and minor version
	parameter are placed in the high word of this object, and the sub-version parameter is the
	low word).
Sub-index 4
Access: RO		Range: N/A	Size: 4 bytes	Unit: N/A
Default:	See Pr MM.35.
Description:	Contains the option hardware serial number.
