Eventlogger

Limitations

Events have a maximum size of 8 kb when transmitted. Make sure that this limit is not exceeded when using the TwinCAT 3 EventLogger. It refers to all elements that are transmitted and described in this documentation, including the dynamic elements (Attributes, SourceName, JSON Attributes).
The interface for receiving events in real-time delivers a maximum of 128 events per clock cycle. Further events are not delivered.
The TwinCAT 3 EventLogger offers a connection to the TwinCAT HMI (TF2xxx). The TwinCAT PLC HMI (TF18xx), conversely, cannot receive the events.
