CPU Information Read (Service Code: 0E Hex)

Reads CPU Unit information, including operating mode, fatal/non-fatal errors, and the CPU Unit model.

Command Block

Class ID	Attribute ID
Service code
Destination	Instance ID

	node address
	No. of bytes
	received
Parameters	Destination node address (command): The node address of the CS/CJ-
	series DeviceNet Unit from which to read the data, specified in 1-byte (2 digit)
	hexadecimal.
	Service code (command, response): 0E Hex is specified for commands.
	For responses, the highest bit be ON and 8E Hex will be returned.

Class ID (command): Always 002F Hex.

Instance ID (command): Always 0000 Hex.

Attribute ID (command): The read information is specified by the attribute ID.

The attribute IDs are listed in the following table.

Attribute ID (Hex)	Contents	Attribute value size
64	CPU Unit operating mode	1 word (2 bytes)
65	CPU Unit errors	1 word (2 bytes)
66	CPU Unit model	22 bytes

•CPU Operating Mode (when Attribute ID = 64 Hex) Reads the CPU Unit operating mode.

•CPU Unit Errors (when Attribute ID = 65 Hex)

Reads if there are any fatal or non-fatal errors in the CPU Unit.

•CPU Unit Model (when Attribute ID = 66 Hex) Reads the CPU Unit model.

No. of bytes received (response): The number of bytes received from the destination node address (remote node) onwards is returned in hexadecimal.

Destination node address (response): The node address of the CS/CJ- series DeviceNet Unit that returned the response is returned in hexadecimal.
