Limitations
- Events have a maximum size of 8 kB during transmission. When using the TwinCAT 3 EventLogger, make sure that this limit is observed. 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 stores a maximum of 1024 events temporarily until they have to be retrieved.
If they are not retrieved in time, events are lost. - The TwinCAT 3 EventLogger offers a connection to the TwinCAT HMI (TF2xxx). The TwinCAT PLC HMI (TF18xx), conversely, cannot receive the events.
