Description
0
_Enet.CCStatus.Active
Controlling Connection Active
This bit is set as long as a Controlling Connection is currently
active. If the connection is closed or timed out, this bit will
be cleared.
1
_Enet.CCStatus.TimedOut Controlling Connection Timed Out
This bit is set when a Controlling Connection timed out.
Notice that this is only one method of a controlling
connection being closed (another example is the PLC
intentionally closing it). This bit is cleared when the
Controlling Connection is re-opened. The user can look for
the rising edge of this bit in the Program Triggers to respond
to a time-out.
A time-out can occur when the cable is disconnected, or
when the client is powered off or reset.
PROFINET controlling connections do not use this bit. Only
the Active bit can be used for PROFINET controlling
connections.
