Post by mejak on Raspberry Pi USB HID RFID Reader - read ID in plc program ^{CODESYS Forge talk (Post)}
Hello, I have an RFID reader that is detected as a keyboard. While looking for information, I came across examples using visualization. I would like to read the ID without visualization or external code in python, only in PLC. I found on the forum that you can try reading directly from potru /dev/... https://forge.codesys.com/forge/talk/Runtime/thread/24b3527036/ How to read values directly in codesys? Or maybe there is another solution? Best Regards

Hello I've just seen this feature: very nice. Using the 'DeviceReader' project previously, I could see the SL possibility too (Dongle or Softkey). Is it possible to get this status too please?

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 opineiro on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.
