CONNECTION SIZES

Device Profile: This product conforms to the DeviceNet specification

Volumes I and II of version 2.0.

Device Configuration: No DeviceNet configuration is supported.

However, some DLC configuration is supported.

SUPPORT CONNECTIONS

Polled Command: The Polled Command produces 4 bytes of data, and is used

to get, or set attributes. The device attribute is determined by the value in byte

0 of the data field. Refer to the Supported Attributes table for the appropriate

value. Byte 1 determines the action: 0 = get, 1 = set. The next 2 bytes are the

new attribute value for the set command. For get commands, enter 2 zeros.

The data response from the Polled Command is in the format of a 2 byte

hexadecimal number. For the get command (0), the response is the attribute

value. For the set command (1), the response is an echo of the data input.

Bit Strobe Command: The data response from the Bit Strobe Command is in

the format of a 2 byte hexadecimal number. The register that will be read

using the Bit Strobe command is determined by setting Attribute 2, Instance

1, Class 100* (decimal) with a value that represents the desired attribute.

Refer to the Supported Attributes table for the appropriate value.

EXPLICIT MESSAGE COMMAND

Get Attribute: The attribute that will be read using the Get Attribute command is

determined by setting Service Code 14, Instance 1, Class 100* (decimal), and

the attribute with a value that represents the desired meter attribute. Refer to the

Supported Attributes table for the appropriate value. The data response from

the Get Attribute Command is in the format of a 2 byte hexadecimal number.

Set Attribute: The attribute that will be set using the Set Attribute command is

determined by setting Service Code 16, Instance 1, Class 100* (decimal), and

the attribute with a value that represents the desired meter attribute. Refer to

the Supported Attributes table for the appropriate value. The data field for the

Set Attribute Command is entered as a 2 byte hexadecimal number.

OTHER EXPLICIT MESSAGE ATTRIBUTES

Data Byte Swap: (1 byte), Attribute 1, Instance 1, Class 100* (decimal). Data

is normally sent and entered as follows: DLC value = 50000 (C350h). 2 byte

value sent would be 50C3. Setting the data swap value to 1 would result in

the data being sent as C350. This attribute can only be set to 0 or 1, all other

values are ignored. The factory setting value is 0. Data byte is saved in

EEPROM memory.

Data Update: The DeviceNet interface is continually requesting values from the

DLC main processor and updating buffer registers. As such, valid attribute

values are always available over DeviceNet at the maximum bus rate.
