Addressing of the parameter and process data objects

The CAN bus system is based on a message−oriented data exchange between a transmitter
and many receivers. Thus, all nodes can transmit and receive messages at the same time.

The identifier in the CAN telegram ˘ also called COB−ID (Communication Object Identifier)
controls which node is to receive a transmitted message. With the exception of the
network management (NMT) and the sync telegram (Sync) the identifier contains the
node address of the drive besides the basic identifier:

Identifier (COB−ID) = basic identifier + adjustable node address (node ID)

The basic identifier is preset with the following values:

Display of the resulting identifiers

The display code for the resulting identifiers is for the

ƒ

Interface X1 (AIF) C2355.

ƒ

Interface X4 (CAN) C0355.

ƒ

Interface X14 (CAN−AUX) C2455.

Here, no values can be entered.

ƒ

General addressing (

^

460):

Identifier (COB−ID) = basic identifier + adjustable node address (node ID)

ƒ

Individual addressing (

^

173):

Identifier (COB−ID) = 384 + ID offset (C0354 or C2454)
