pg. 14
At any point, if the manager sends a Reset Communication or Reset Module (warm boot), the eXm
will go to the Initialization state as if there were a power-cycle.
Baud Rates
e eXm will run at one of ve selectable baud rates: 125k, 250k, 500k, 800k, and 1M. Rates below
125k are not supported.
e baud rate can be changed by an SDO. Changes in the baud rate require an NMT rest or key-cycle
to make the new rate active.
Node Addresses
e node address of the eXm can be 1 to 127 and is used by CANopen to route messages to the eXm
and to denote messages from the eXm. e node address is part of the COB-ID and therefore also
plays a part in message priority and bus arbitration.
Changes to the node address require an NMT reset or power-cycle.
Standard Message Identifiers
The eXm will produce—and respond to—the standard message types with the following
CANopen identifiers.
Message Type Message Identifier
NMT 0000 – 00h
EMERGENCY 0001 – 01h
TPDO1 (TX) 0011 – 03h
RPDO1 (RX) 0100 – 04h
SDO-TX 1011 – 0Bh
SDO-RX 1100 – 0Ch
HEARTBEAT 1110 – 0Eh
e 11-bit identication eld is a xed part of the CANopen specication called the Communication
OBject IDentication (COB-ID). is eld is used for arbitration on the bus. e COB-ID with
the lowest value gets priority and wins arbitration. Consequently, NMT messages have the highest
priority of the standard message types, and the heartbeat has the lowest priority.
e standard organization of the COB-ID puts the message type in the upper four bits, and the Node
ID in the bottom seven bits:
11 10 9 8 7 6 5 4 3 2 1
Message Type Node ID
