Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again....

Hi everybody, As I did not still findout a proper answer for my question no.3 above, it would be highly appreciated if anybody can answer my question. For reference I repeated my question as bellow: In case of any problem in device or driver (for example disconnecting or cable unplug) How could I send errors to the codesys? What is the best practice to handle such a situation?

Thank you for your kind respond, Ingo! 1- The "IoConfigLateInit" trick got the job done! But, still for some functions like "IoDrvWriteParameter" I could not place break point. 2- Regarding the page, as you set it correctly, I mean pages like EtherCAT and so on. A sample page for this you can find as attachment. So how could I write a plugin and use it in my IO Driver? Because my device uses several configuration and also has some diagnostic registers that would be perfect if I could show them to...

Hi kdkwhite, for Word you still can use suggested code by using a union structure and crack down your Word to two byte as bellow: TYPE CrackWordToByte : UNION InWord : WORD; OutBytes : ARRAY [0..1] OF BYTE; END_UNION END_TYPE then define your variable as this type: udInput : CrackWordToByte; now assign your Word variable input to InWord and send OutBytes[x] to the mentioned method: udInput.InWord := WordVariableInput; Input := udInput.OutBytes[x]; Regarding your question about the code: actually...

Hi Ingo, Thank you for your nice introduction. I have created a library successfully based on your prepared templates and now, I have following questions: 1- How could I possibly debug my developed FB library that implementing the I/O driver interface library. This also can help me to check the data that are going back and forth between device description and the FB library to know better how things are working and which other options I have. 2- I found out that some other device drivers have more...
