CAN Identifier Field 

The CAN Identifier Field is a single 11-bit field that defines the components of a DeviceNet 
connection (Table 17, page 48). This information is required for both explicit and I/O poll 
messaging connections. The CAN Identifier Field consists of the following three components: 

 

Message ID (Group 1 or 2) 

 

Node Address (network address) 

 

Message Type ID 

Message ID 

This fixed 2-bit field indicates the type of messaging used in the device.  
The identifier for Group 2 messages is fixed with bits 10 and 9 set to 1 and 0 respectively.  
The identifier for Group 1 messages is fixed with bits 10 and 9 set to 0 and 1 respectively. 

Node Address 

The Node Address is a 6-bit field that identifies the network address of the device 

as a 

hexadecimal value

. The 

source

 node address is the address of the device sending the message. 

The 

destination 

node address is the address of the device receiving the message. 

In a request message, the device address in the CAN Identifier Field is the destination

 

node 

address. In a response message it is the source node address. 

Message Type ID 

This 3-bit field identifies the specific type of message (explicit or I/O) and whether the message 
string is a request or a response. The message type IDs are fixed for the Predefined Master/Slave 
Connection Set [1]. 

Note

 

The CAN Identifier Field is represented by a single hexadecimal value in each 
message string.
