Hi. Does anyone know how to fix a problem with losing focus of a variable in FBD editor. Sometimes when trying to edit variable name, array index, etc. in network, editor randomly exits "text edit mode" and variable is replaced by text you were typing.

I need to connect 2 computers on the same network that are running codesys, so that they can receive and change variable values from each other. This connection must preferably be made using Modbus.

Hi William, I struggled in the same way as you at the beginning with the recipe manager. This chapter helped me a lot to understand how it has to be used: https://content.helpme-codesys.com/en/CODESYS%20Recipes/_rec_start_page.html Check out the Methode LoadFromAndWriteRecipe / LoadAndWriteRecipe Good luck!

Maybe your question makes sense but I don't see it. Maybe you should rephrase and add a lot of detail

You never stay in a method. You need a block to do that. Something like: VAR button:BOOL:=FALSE; count:UINT:=0; END_VAR IF button THEN //read pressure count:=count+1; IF count>1 THEN button:=FALSE; count:=0; END_IF END_IF

Thank you @eschwellinger Even tough I think the content of the link you provided is a bit messy. To bind OPCUA server to a specific adapter, I should have had insert the following section. [CmpOPCUA] NetworkAdapter=eth0 But it doesn't work, I had to insert the following section instead to get the right configuration. [CmpOPCUAServer] NetworkAdapter=eth0 Regards Rossano

I'd like to know if it is possible to have the "Name" field, in the recipe definition, language dependent. Something like to have the possibility to put there a string ID that will be add to the GlobalTextList. In this way it can be translated and when showed in a Visualization screen its value depend on the current language. Thanks.

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.

i know, this is the reason for us either. PLC-Handler is to big, and only available with additional Contracts/Costs. OPC-UA is to slow for us. As described, there is a solution available, but im not allowed to post them here. i would prefer you send a message at codesys store by "have a question" or similar called. Not sure. Or, if an Codesys-Official Member allows to share that informations, i can give you the right hints.

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.
