Post by apurv on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
okay but will this pass the array by copying it or it will be a reference to original array only.

I tried to change the name of the tap device to 'tap0,' but nothing changed. I don't think this is the problem.

Post by smartcoco on Bit / Bool data types in function parameters ^{CODESYS Forge talk (Post)}
Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

Hi there, I am having a similar problem like you. I have 3 screens connected to one PLC. I have set 3 different URLs for them. But 3 of them are still dependent to each other. How can I make them independently ? Kind regards, Jin.

Post by ruben on DataSource not working ^{CODESYS Forge talk (Post)}
I had the same error. It took me a LONG way to figure it out, but in my case the problem was that I used LDATE_AND_TIME. It seems to be not supported, at least not in the Codesys version I used (3.5.16)

Maybe shared memory is an opinion for you to give it a try: https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_cds_shared_memory_communication.html

Post by alex00 on DCS / Central Engineering with Codesys support ^{CODESYS Forge talk (Post)}
Hello together I'm currently investing in possibilities to have a central engineering software / system for Codesys based controllers. Something like a DCS / SCADA depending on where you see the functionality. We plan to use more or less vanilla codesys. The tool should support the following: - Connect to multiple PLC's in a project to see its variables and debug it. - Central Engineering capabilities (for example shared libraries in a project). - Download the new code / binaries to the plc. - Maybe have functionality to combine visualization elements and logic together. - See the live status variables on all the systems (crosscommunication). I see that codesys theoretically supports engineering of multiple PLC's, but I couldnt find to much functionality for a DCS type of operation, but that could be lack of knowledge. Any tips from you? Is Codesys good enough for this and maybe there are some manufacturers which build around it? Or are there good tools on the market with Codesys support (and the engineering is separate, but download to codesys possible). The use case is distributed energy installations like Heating pumps, Photovoltaics, etc. All these installations should have a PLC with codesys installed and run in one larger network, the PLC's are connected via VPN. Thanks for your inputs Greetings

Try setting up your project environment. You can do this under Project -> Project Environment -> Press Button "Set all to newest". You have set your compiler, devices, etc in this project to the newest available versions.
