AzureMQTTClient (FB) ¶ FUNCTION_BLOCK AzureMQTTClient Function block to connect to Azure IoT Hub via MQTT. InOut: Scope Name Type Initial Comment Input xEnable BOOL TRUE: Opens a connection, FALSE: Close connection uiKeepAlive UINT 10 Keep alive interval in seconds (default: 10s) tPingInterval TIME TIME#2s0ms Ping interval (default: 2s) udiTimeOut UDINT 0 Defines the time (µs) after which the connection setup aborts with xError. tReconnectTime TIME TIME#0ms Time for an automatically reconnection, default is T#0s and reconnection is not acitve. sHubDomainName STRING(255) Domain name of the IoT Hub sDeviceId STRING(255) Device ID wsSaS WSTRING(255) Shared Access Signature (SAS Token) pbWillMessage POINTER TO BYTE 0 Pointer to the ‘Last Will’ message (optional) uiWillMessageSize UINT 0 Size of ‘Last Will’ message (optional) 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. Use this property if the connection setup takes longer than one task cycle (e.g. TLS connections) Output xError BOOL TRUE, if an error occurred xBusy BOOL TRUE, while the function block is active eError MQTT.MQTT_ERROR The error id xConnectedToBroker BOOL FALSE FALSE when there is no connection to Azure IoT Hub, otherwise TRUE
