Post by viksym on Get text from textlist

Does anybody know how to get a specific text from a text list within a program. Obviously it works in a visualization, but because I will have an HMI that has it's own system and I will have to send variables to this HMI via an OPC UA connection, I need to be able to get a text into a string. I tried using the VisuElems like this, but it only returns an empty "" and nothing else. IF trig THEN sText := VisuElems.cmpDynamictext.DynamicTextGetDefaultText(ADR(sTextList), ADR(sAlarmID))^; //sText := VisuElems.cmpDynamictext.DynamicTextGetText(ADR(sTextList), ADR(sAlarmID))^; trig := FALSE; END_IF Any help and idea is highly appreciated because I am getting desperate here.

Previously, I have used ModbusEthernet_04 library for Wago for ModbusTCP Master communicational in Codesys V2.3. How to use same communication of similar UDT for Opto22 Groov PR2 PLC in Codesys V3.5 SP20. Can I use OSCAT library - Network -MB_Client or IODrvModbusTCP - ModbusRequest for this requirement? If any other please guide.

I think you will find something in the libary TexlistUtils: https://content.helpme-codesys.com/en/libs/TextListUtils/Current/index.html

Hallo, und vielen Dank für die Antwort. Ich habe 'Modbus_Slave_COM_Port' in eine Watchliste genommen. Leider reichen meine Kenntnisse nicht aus, um aus dem Ergebnis irgendwelche Schlüsse zu ziehen. xBusy und xError wechseln zwischen true und false (im Gegentakt), der angezeigte Fehler ist 'Response Timeout'. iChannelIndex wechselt zwischen 0 und -1. Wenn ich das richtig verstehe bedeutet das wohl, das der Servotreiber auf Anfragen einfach nicht reagiert. Ich hänge einen screenshot vom Watchfenster an, vielleicht kann jemand mehr herauslesen als ich. Nochmal danke fürs Lesen und Überlegen!
