Go in Windows to this location. Right click on this file and go to properties. Is it in Read-only state? Then CODESYS cannot open in Write mode.

Dear all, I've just started to migrate some of my ancient projects to SP20. There is one strange error (?) I have noticed so far. In a method call, depending on the circumstances I would like to return reference to an object, or an invalid reference: METHOD Add_EVT_OUT : REFERENCE TO FB_MSG VAR END_VAR IF __ISVALIDREF(refMSG_Entry) THEN Add_EVT_OUT REF= MANAGER.AddMsg_EVT_OUT( refMSG_Entry, _Get_EVT_Message(MSG_EVENT.OUT), _Get_EVT_AddCode(MSG_EVENT.OUT) )^; ELSE Add_EVT_OUT := 0; END_IF So far setting a reference variable to 0, did this. But now, the expression Add_EVT_OUT := 0; gives an error: [ERROR] DB_WTP_370: Add_EVT_ACK MSG_TRIGGER_EXT: C0032: Cannot convert type 'BIT' to type 'REFERENCE TO FB_MSG' Naturally... I can write: Add_EVT_OUT := DWORD#0; But is this the correct way? Is there any constant I could use instead, like "NULL"? Or this is totally wrong and to be avoided?

Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.

What worked for me with this error was to go to Tools -> Update Raspberry Pi, select Install, and from the popup screen, there are options to change your installation (I changed it to single core, instead of multicore), and I was then able to connect to my Rpi 4.

@eschwellinger, I don't understand what you mean by 'CANfox must also go' (English translation). Do you mean that the support for the CANfox must go? Have you any guidance as to get this working?

Hey Guys, could you give a explaination of how to change the g_udiMaxPacketSize from 6000 to 100000 and g_udiMaxPayloadSize from 4096 to 80000 ? When I go to the library the parameter is not editable. I would really appreciate it :) Kind Regards

Open the CODESYS Installer (from the menu Tools). Go to Browse. Search for: help ... Select the CODESYS Offline Help which you would like to install. (probably you have to close CODESYS to install it and reopen it after installation).

I ended up figuring it out It wasn't in my code. It kept taking me to 2 of my visualizations but it wasn't going to anything specific. Figured out it was some arrows that I had made to buttons for a mouse click to go to the other visualizations. I removed the text in the assign box but didn't remove the action "change shown Visualization from the list. If I deleted the images all together, the error went away. That's how I thought to go look at that.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
