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...
