Post by alsiddhartha on TextList name error (fake) ^{CODESYS Forge talk (Post)}
Hello, I’m developing a program and for some reason I got this error: C0193: Name '2,Recipe #2GVL' is no valid identifier I was creating a combo box and creating a TextList for my recipe. I couldn't find where the error was, until in the combo box properties in the 'Text List' property in the options it gives me to select, I found '2,Recipe #2' to be able to select (I never created a list with this name) and I can't find a way to delete that option or I can't find where that list is. I tried to delete the TextLists, delete the combo box, to clean the project, but the error still there. How can I delete this option (2,Recipe #2)? Or how can I fix this error?** Thank you.

I'm not sure, but maybe you need to install or update the "CODESYS Communication" add-on through the CODESYS Installer.

I have now and it works. I had the idea that it had something to do with codesyscontrol.cfg, but where can I find a description of all the things you can set in codesyscontrol.cfg and its syntax?

Post by nixola on Exception handler return value purpose in _CODESYS 3.5 ^{CODESYS Forge talk (Post)}
Hi, I was trying to figure out how to correctly handle system exceptions in a CODESYS project, but either the documentation falls short, or I'm unable to find the proper docs. I know I can register a function as an exception handler via Task Configuration > System Events > Add Event Handler, which will create a function with the correct interface; I am, however, unable to figure out what the returned DWORD is supposed to be, if anything. Is the interface for the exception handler documented and, if so, where can I find it?

Have you cross referenced the variable to see if it is being written some where else? You could try an Execute block instead of a Move.

Post by runtimevictor on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
Hello, In Codesys I can't find where to configure Ethercat Master VLAN tagging? In Beckhoff in Infosys there is an attached image so you can see it... I would like to try ethercat master with VLAN, to try to have several ethercat masters on a single ethernet port... I imagine that managed VLAN switches are also necessary? Thanks.

Post by george32 on TCP Server ^{CODESYS Forge talk (Post)}
Dear people, I would like to create a TCP server in my PLC program. The TCP server needs to communicate with an external device. I have been searching the internet and found that the libraries Syssocket or CAA NetBaseSrv are two possible solutions to create a TCP server. From what I have read, CAA NetBaseSrv is more user-friendly to implement than the Syssocket variant. However, I am still struggling to actually implement this library. Foremost is my little knowledge about creating a TCP server and how to read/understand each function block, especially the outputs of some blocks and the types, e.g. server has an output CAA.Handle, but I cannot find the explanation of CAA.Handle. I tried to find a good document that can help me understand how to implement a TCP server, but I could not find it. Thank you in advance, George
