Server (FB)¶

FUNCTION_BLOCK Server EXTENDS CBM.ETrigTo

The server is essential to send, receive and delete emails. The Server must be started before any action can be performed.

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	xExecute	BOOL		Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (xDone, xError) are present at the outputs for exactly one cycle.	ETrigTo
	udiTimeOut	UDINT		Defines the time (µs) after which an FB (e.g. requiring an external acknowledgement) aborts operation due to a timeout with error message.	ETrigTo
Output	xDone	BOOL		TRUE: Action successfully completed	ETrigTo
	xBusy	BOOL		TRUE: Function block active	ETrigTo
	xError	BOOL		TRUE: Error occurred, function block aborts action FALSE: No error	ETrigTo
Input	sPopServer	STRING		The name of the POP server.
	uiPortPOP	UINT	110	The port of the POP server.
	sSMTPServer	STRING		The name of the SMTP server.
	uiPortSMTP	UINT	25	The port of the SMTP server.
	eConnectionType	CONNECTION_TYPE	CONNECTION_TYPE.STD	Communication via TLS or standard, default: STD
	xStartTLS	BOOL		Use STARTTLS for the SMTP connection (condition: eConnectionType = CONNECTION_TYPE.TLS)
	itfTLSContext	NBS.ITLSContext	0	Encapsulates all the data neccecray to handle encrypted tcp connections Static initialization, as shown in the following code snippet. VAR commonName : STRING := 'MyRrasPi'; ciCertInfo : NBS.CERT_INFO := (psInfo:=ADR(commonName), udiSize:=LEN(commonName)); myTLSContext : NBS.TLSContext := ( ePurpose:=NBS.PURPOSE.CLIENT_SIDE, sUseCaseName:='NBSTest', sTLSVersion:='1.3', ciCertInfo:=ciCertInfo, udiVerificationMode:=2 ); END_VAR
	itfAsyncProperty	NBS.IAsyncProperty	0	Runs the connect process in a own background task, usage see library Net Base Services
Output	eError	ERROR		Local library error ID (0: no error; 5001: time out)
