NT_GetTime
The local Windows system time of a TwinCAT system can be obtained using the "NT_GetTime" function block (the local Windows system time is displayed in the task bar). The year, month, day, day of the week, hour, minute, second an millisecond are placed in the variables in the structure TIMESTRUCT. Internally, an instance of the ADSREAD function block is called.
VAR_INPUT
VAR_INPUT
NETID :T_AmsNetId;
START :BOOL;
TMOUT :TIME := DEFAULT_ADS_TIMEOUT;
END_VAR
NETID: It is possible here to provide the AmsNetId of the TwinCAT computer whose local Windows system time is to be read. If it is to be run on the local computer, an empty string can be entered.
START: The function block is activated by a positive edge at this input.
TMOUT: States the length of the timeout that may not be exceeded by execution of the ADS command.
VAR_OUTPUT
VAR_OUTPUT
BUSY :BOOL;
ERR :BOOL;
ERRID :UDINT;
TIMESTR :TIMESTRUCT;
END_VAR
BUSY: When the function block is activated this output is set. It remains set until and acknowledgement is received.
ERR: If an ADS error should occur during the transfer of the command, then this output is set once the BUSY output is reset.
ERRID: Supplies the ADS error number when the ERR output is set.
TIMESTR: Structure with the local Windows system time.
Further time, time zone functions and function blocks:
FB_TzSpecificLocalTimeToSystemTime, FB_TzSpecificLocalTimeToFileTime, FB_SystemTimeToTzSpecificLocalTime, FB_FileTimeTimeToTzSpecificLocalTime, FB_GetTimeZoneInformation, FB_SetTimeZoneInformation, NT_SetLocalTime, NT_GetTime, NT_SetTimeToRTCTime, F_TranslateFileTimeBias, FB_LocalSystemTime
