Function blocks for using the TC3 EventLogger

FB_ListenerBase2	Basic implementation of an event listener.
FB_TcAlarm	Represents an alarm of the TwinCAT 3 EventLogger.
FB_TcArguments	Defines arguments of an event.
FB_TcEventLogger	Represents the TwinCAT 3 EventLogger itself.
FB_TcMessage	Represents a message from the TwinCAT 3 EventLogger.
FB_TcSourceInfo	Defines the source information of an event.

Asynchronous text requests

F_GetEventClassName	Triggers the asynchronous request for the name of an event class.
F_GetEventText	Triggers the asynchronous request for an event text.
FB_AsyncStrResult	Enables the asynchronous request for a text.
FB_RequestEventClassName	Enables the asynchronous request for the name of an event class.
FB_RequestEventText	Enables the asynchronous request for an event text in the desired language.

EventEntry conversion

AdsErr_TO_TcEventEntry	Converts a standard ADS error into a TcEventEntry.
HRESULTAdsErr_TO_TcEventEntry	Converts a standard ADS error (HRESULT) into a TcEventEntry.
TcEventEntry_TO_AdsErr	Converts a TcEventEntry into a standard ADS error.
TcEventEntry_TO_HRESULTAdsErr	Converts a TcEventEntry into a standard ADS error (HRESULT).
