SNTPGetUTCTime (FB)¶

FUNCTION_BLOCK SNTPGetUTCTime

Sends a SNTP request to a NTP/SNTP server and reads the current server time.

InOut:

Scope	Name	Type	Initial	Comment
Input	xExecute	BOOL		A rising edge starts the SNTP request
	sSNTPServer	STRING(255)		IP address of the NTP/SNTP server
	sOwnIP	STRING(255)	‚0.0.0.0‘	Optional: IP address of the PLC, Default: 0.0.0.0
	uiSNTPPort	UINT		Port of the NTP/SNTP server
	uiOwnPort	UINT		Own port
	udiTimeout	UDINT	1000	Timeout in ms (default 1000)
	eNTPVersion	NTP_VERSION	NTP_VERSION.V3	Version of the NTP protokol (default V3)
Output	xDone	BOOL		True if the call has been finished
	xBusy	BOOL		True while the request is running
	xError	BOOL		True if an error occured.
	eError	ERROR		Error code
	uliTimestamp	ULINT		Current UTC time in milliseconds since 1.1.1970 of the NTP/SNTP server with roundtrip correction. You can use the function SysTimeRtc.SysTimeRtcConvertHighResToLocal to convert the UTC time to SysTimeRtc.SYSTIMEDATE.
	uliReceiveClientTS	ULINT		Current UTC time in milliseconds since 1.1.1970 when the timestamp has been received by the client (current time of the runtime). You can use the function SysTimeRtc.SysTimeRtcConvertHighResToLocal to convert the UTC time to SysTimeRtc.SYSTIMEDATE.
