TcEvent
 | TwinCAT EventLogger vs. TwinCAT 3 EventLogger The TwinCAT EventLogger was replaced by the successor TwinCAT 3 EventLogger. The older TwinCAT EventLogger is supported by TwinCAT 3 up to version 3.1.4024. Newer TwinCAT versions (>= 3.1.4026.0) only support the newer TwinCAT 3 EventLogger. PLC function blocks for this can be found in the PLC library Tc3_EventLogger. |
