Response Block

			Service Code
			Destination node address
		No. of bytes received
Parameters	Destination node address (command): The node address of the CS/CJ-
	series DeviceNet Unit to which to write data, specified in 1-byte (2 digit) hexa-
	decimal.
	Service code (command, response): 10 Hex is specified for commands. For
	responses, the highest bit will turn ON and 90E Hex will be returned.
	Class ID (command): Always 002F Hex.
	Instance ID (command): Always 0000 Hex.
	Attribute ID (command): Information to write 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)

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

The Attribute Values are as follows:

0001 Hex: PROGRAM mode; 0002 Hex: MONITOR mode;

0004 Hex: RUN mode

Note The specified code for the above operating modes are 1-word (2-byte data, and are specified with the low byte first. For example, for PRO- GRAM mode, the code is specified as 01 Hex followed by 00 Hex. Ac- cordingly, the low to high bytes for the above codes are set as high to low bytes in I/O memory, when setting the codes as data for oper- and S of CMND(490).

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

Clears any fatal or non-fatal errors in the CPU Unit. Sets the error clear code to Attribute Value. The error clear codes are listed in the following table.

Error code	Data cleared
(Hex)
FFFE	Current error (clears the highest priority error)

0008B	Interrupt task error

009A	Basic I/O error

009B	PC Setup error

02F0	Inner Board non-fatal error

0300 to 035F	Special I/O Unit error

00A0 to 00A1	SYSMAC BUS error

0500 to 055F	Special I/O Unit settings error

00E7	I/O verification error
	When registered and actual I/O tables are different
	When disconnecting or connecting I/O Units
