8.1.5 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 for the ECSxE power supply module is preset ex works with the
following values:
Object
Basic identifier
dec hex
Network management (NMT) 0 0
Sync telegram 128 80
