of the controlling connection. Notice that Controlling Connection can be either a
PROFINET or EtherNet/IP IO connection.
Tag Name Description
_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.
_Enet.CCStatus.TimedOut Controlling Connection Timed Out
This bit is not used for PROFINET.
_Enet.PLCStatus Controlling PLC Status
This register indicates the state of the controlling PLC. This
register (DINT data type) can hold one of three values:
Unknown (0), Run (1), and Program (2). The Unknown state
applies whenever no controlling connection is active.
To find these registers when editing the Program Triggers or a User Program, use the
Address Selection tree and browse to:
Controller > Communication Settings > Ethernet
6.8.10.7.6. Troubleshooting PROFINET
Using the Event Log
The Event Log is the primary troubleshooting tool in the RMC for PROFINET I/O. It will
report each time a PROFINET I/O connection is opened or closed and report errors with
the connection as well. It can also record every change in the incoming (consumed)
PROFINET I/O data (the Output Data from the PLC). It does not record the outgoing data
sent by the RMC (the Input Data in the PLC).
The Event Log can report the following events based on Incoming I/O Data:
• Initial Data
This entry is logged only if the Sync Register is used and the Ethernet I/O Logging
filter option for the Event Log is set to All. It is reported when the first incoming I/O
data is received after a new controlling I/O connection is established, showing both the
data and the value of the Sync In register. Notice that the data is not yet applied to
the RMC.
• Data Changed
This entry is logged only if the Sync Register is used and the Ethernet I/O Logging
filter option for the Event Log is set to All. It is reported when any Incoming I/O Data
register has changed, but the Sync In register has not. This entry shows both the data
and the value of the Sync In register. Notice that the data is not yet applied to the
RMC.
• Request Made
This entry is logged each time the incoming I/O data is applied to the RMC. If the Sync
Register is used, then this is each time the Sync In register changes. If the Sync
Register is not used, then this occurs when the I/O data is first received, and each
time after that when any register in the Incoming Data changes. This log entry will be
shown by default, but can be disabled by setting the Ethernet I/O Logging filter
option for the Event Log is set to None.
Using the Communications Statistics
To open the Communication Statistics window, in the Project Pane, select the desired
controller. On the Controller menu, choose View Communication Statistics.
