<H2>CANopen protocol - Special function objects</H2>
<P>CANopen also defines three specific protocols for
synchronization, emergency indication, and time-stamp
transmission. <BR></P>
<H3><A name=sync></A>Synchronization object (Sync)</H3>
<P><IMG height=146
src="CAN in Automation (CiA) - CANopen protocol - Special function objects.files/sync.gif"
width=300 align=left border=0>The Sync Object is
broadcast periodically by the Sync Producer. The time
period between Sync messages is defined by the
Communication Cycle Period, which may be reset by a
configuration tool to the application devices during the
boot-up process. There can be a time jitter in
transmission by the Sync Producer due to some other
objects with higher prior identifiers or by one frame
being transmitted just before the Sync message. The Sync
message is mapped to a single CAN frame with the
identifier 128 by default. The Sync message does not
carry any data.<BR><BR><BR></P>
<H3><A name=emcy></A>Emergency object (Emcy)</H3>
<P><IMG height=145
src="CAN in Automation (CiA) - CANopen protocol - Special function objects.files/emcy.gif"
width=300 align=left border=0>The Emergency message is
triggered by the occurrence of a device internal error
situation and are transmitted from an Emergency producer
on the concerned application device. This makes them
suitable for interrupt type error alerts. An Emergency
message is transmitted only once per 慹rror event⌨️ 快捷键说明
