track of all nodes connected and ensures that the connected nodes<br />
are configured correctly.<br />
Change-of-state (COS)<br />
Generic I/O modules typically monitor their inputs for changes.<br />
<strong>CANopen</strong> nodes can be configured to only transmit this input data,<br />
if a change was detected.<br />
Connection Object Identifier, COB-ID<br />
The COB-ID specifies the CAN message details used for a specific<br />
connection. These include a (CAN) Message Identifier and typically<br />
an enable/disable bit.<br />
Default Connection Set<br />
The default connection set determines which (CAN) Message<br />
Identifier is used for which purpose in a <strong>CANopen</strong> network.<br />
Typically (CAN) Message Identifiers are assigned using a base<br />
identifier (such as 180h for TPDO1) and adding the Node ID to that<br />
base identifier.<br />
Emergency, EMCY<br />
<strong>CANopen</strong> emergency messages have a default (CAN) Message<br />
Identifier of 80h plus the Node ID of the node generating the<br />
emergency. Emergency messages contain a <strong>CANopen</strong> specified<br />
emergency code, the error register [1001h,00h] and a manufacturer<br />
specific emergency code.<br />
Event Time<br />
For TPDOs the Event Time specifies the periodic time at which<br />
TPDOs get transmitted. The Event Time is specified in multiples of<br />
milliseconds and typically only used if the Transmission Type is set<br />
to 255d/FFh.<br />
Heartbeat Producer and Consumer<br />
In <strong>CANopen</strong> the recommended function to monitor the health of<br />
network nodes is to use the heartbeat mechanism. Each <strong>CANopen</strong><br />
