CAN Emergency Messages

Every type of CANOpen node can transmit an emergency message. These messages are designed to report errors and warnings, as well as fatal problems on a node. The contents of these emergency messages are very dependent upon the node manufacturer and node type. To interpret this data, you will need to refer to the node manufacture's data. If an emergency message is generated by a node, the event handling scheme described in the events section below allows the user's application to receive the emergency message data.
