Task time
The time with which the EtherNet/IP is to operate is specified with the SyncTask. Two methods are available
here:
SyncTask via Mapping – in this case the task is used with which the variables are linked. That is usually the
PLC task. However, if the PLC is to be stopped, for example by breakpoints, the task is no longer processed.
The consequence of this is that the EtherNet/IP is also no longer triggered and the EtherNet/IP master goes
into the error state.
SyncTask via Special Sync Task - in this case an additional task is used that is automatically started with
TwinCAT. This runs in its own cycle and is therefore also independent of other tasks that are linked with the
variables.

Diagnostics
Two steps are necessary for the diagnosis. Firstly the monitoring of the EtherCAT status with
"ECatState" (red), which must be equal to "0". Secondly the monitoring of the Ethernet/IP status in the State
(green). State = 0x8000 is a configuration error; in this case the I/O connection must be checked. If State =
0x0001 an error has occurred in the Ethernet/IP data exchange. If the value has already been "0", this is
usually a watchdog error. This means that the data did not arrive at the Ethernet/IP master within the set
watchdog time. The Ethernet/IP cycle time should be increased if this error occurs frequently. If the State is
already 0x0001 at the start of communication you should check and read out the "DiagHistory" (tab on the
EL6652. See chapter Diagnostic History [} 128]).
