Post by joshskellig on Publish a JSON payload via MQTT Publish (using IIot Libraries) CODESYS Forge talk (Post)
I am trying to figure out how to get a JSON payload to properly publish to my MQTT Broker. I am able to generate JSON using the examples from Codesys, but when I send that payload via MQTT there are characters that are extra or not recognized by my MQTT client. Any idea what could be causing it? PROGRAM PLC_PRG VAR hostname: STRING := 'localhost'; port: UINT := 1883; topic: WSTRING(1024) := "testing/"; payload: BYTE; factory : JSON.JSONDataFactory; eDataFactoryError : FBF.ERROR; pJsonData : POINTER TO JSON.JSONData := factory.Create(eError => eDataFactoryError); fb_JBuilder : JSON.JSONBuilder; wsValue : WSTRING := "Value1"; diRootIndex, diObject1Index : DINT; iValue : INT := 1234; jsonArrayWriter : JSON.JSONByteArrayWriter; wsJsonData : WSTRING(1000); xFirst : BOOL := TRUE; mqttClient: MQTT.MQTTClient; mqttPublish: MQTT.MQTTPublish; mqttPublishProperties: MQTT.MQTTPublishProperties := (bPayloadFormatIndicator := 1, wsContentType := "application/json"); END_VAR // Json Functionality IF xFirst THEN fb_JBuilder(pJsonData := pJsonData, diRootObj => diRootIndex); fb_JBuilder.SetKeyWithValue("Key1", wsValue, diParentIndex := diRootIndex); diObject1Index := fb_JBuilder.SetKeyWithObject("Key2", diParentIndex := diRootIndex); fb_JBuilder.SetKeyWithValue("Key3", iValue, diParentIndex := diObject1Index); xFirst := FALSE; END_IF jsonArrayWriter(pwData := ADR(wsJsonData), udiSize := SIZEOF(wsJsonData), jsonData := pJsonData^, xAsyncMode := FALSE); MSU.StrTrimW(pString:= ADR(wsJsonData)); // MQTT Functionality mqttClient( sHostname:=hostname, uiPort:=port, eMQTTVersion:=MQTT.MQTT_VERSION.V5 ); mqttPublish( mqttClient:=mqttClient, pbPayload:=ADR(wsJsonData), udiPayloadSize:=SIZEOF(wsJsonData), wsTopicName:=topic, mQTTPublishProperties:=mqttPublishProperties );

Post by marek71 on Ambiguous use of name - CO136 CODESYS Forge talk (Post)
My PLC is WAGO PFC200 Firmware Revision 26. target After updating WAGO_Devices_and_Libraries with newer Firmware 27, CODESYS wants to update all libraries to new versions. I will only add that I did not update the Firmware in the PLC. After compiling the program, I received the following errors: ------ Build started: Application: Device.Application ------- Typify code... [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): FbSerialInterface_internal: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): FbSerialInterface_internal: C0136: Ambiguous use of name 'RTS_IEC_RESULT' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): Initialize [FbSerialInterface_internal]: C0032: Cannot convert type 'Unknown type: 'RTS_INVALID_HANDLE'' to type 'POINTER TO BYTE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): Initialize [FbSerialInterface_internal]: C0136: Ambiguous use of name 'RTS_INVALID_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): Initialize [FbSerialInterface_internal]: C0046: Identifier 'RTS_INVALID_HANDLE' not defined [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_is_tx_empty: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_get_line_state: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_is_line_available: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): COMSW_SET_MODE: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' [ERROR] wagosyscom_internal_pfc, 1.0.2.5 (wago): comextra_set_line_state: C0136: Ambiguous use of name 'RTS_IEC_HANDLE' Compile complete -- 10 errors, 0 warnings Build complete -- 10 errors, 0 warnings : No download possible The problem was caused by the WagoSysPlainMem(WAGO) library in the original version 1.5.3.0 after updating to 1.5.3.1. After returning to version 1.5.3.0, the problems disappeared. Probably the version number of this library is responsible for supporting the appropriate Firmware Revision. Can anyone confirm or deny my suspicions?
