5.4 Synchronization object (Sync object)
Typical applications of CANopen need a system-wide clock, with which all inputs and outputs are
synchronized. As a basis for this, CANopen provides the communication cycle.
The communication cycle is defined by specific synchronization messages, which have a very high priority.
The identifier for the synchronization message is defined in object 1005
hex
.
5.5 Emergency object (Emcy object)
An emergency message is triggered as soon as the ATM60-Cxx has detec ted an internal error. One
emergency message is sent for each error which has occurred. The following error messages are supported
by the emergency object:
