Post by baltzer on ICertificateVerifier.VerifyCertificate doesn't appear to override an ERR_CERT_HAS_EXPIRED rejection in TCP_Client.Upgrade() ^{CODESYS Forge talk (Post)}
Follow-up: working workaround found (routing TLS outside CODESYS) For anyone finding this thread later with the same problem (a third-party device presenting a self-signed and/or expired certificate that ICertificateVerifier/udiVerificationMode won't let you connect through) - we never got a working fix within NBS itself, but found a practical workaround worth sharing. Approach: run a local TLS-terminating proxy on the same host as the CODESYS runtime, and have CODESYS talk plain, unencrypted TCP to it instead of connecting to the remote device directly over TLS: CODESYS --plain TCP--> 127.0.0.1:<port> --stunnel/TLS--> <remote device>:<port> We used stunnel (client mode), with certificate verification explicitly disabled at that layer (verifyChain = no, verifyPeer = no) - a simple, well-documented one-line option, unlike anything we could get working inside NBS. Running it as a systemd service with Restart=always means it survives reboots and recovers automatically if the proxy or the remote device drops. On the CODESYS side, this required no changes beyond pointing TCP_Client at 127.0.0.1 instead of the device's real IP, and removing the TLSContext/ICertificateVerifier code entirely - the rest of our application-layer logic (framing, checksums, etc.) was completely unaffected, since none of that ever depended on where the TLS termination happened. Confirmed working end-to-end against a real device with an expired self-signed certificate, running on CODESYS Control for Raspberry Pi SL (Linux). We haven't yet set this up on Windows - stunnel does have Windows builds available, so the same general approach should be possible there too, but that combination isn't tested or confirmed by us at this point. Caveat: this only makes sense when the proxy and the CODESYS runtime are on the same trusted host (in our case, both on the same Raspberry Pi) - don't expose the proxy's plaintext side on a reachable network interface, since that would create an unauthenticated plaintext path to the device. The original question - whether there's a supported way to override an ERR_CERT_HAS_EXPIRED/self-signed rejection from within NBS's own TLSContext/ICertificateVerifier - remains open as far as we know. Still happy to hear from anyone who's solved that particular piece, since the workaround above is a practical detour rather than an actual answer to the original question.

Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

Post by pedegani on "Do you really want to perform" dialog boxes ^{CODESYS Forge talk (Post)}
I have the same annoying problem. The confirmation prompt for every single action appeared recently after an update from CODESYS 3.5 SP20 Patch 3 to Patch4, but I don't think it's due to this. Having to confirm every operation while debugging an application is a considerable waste of time and does not help at all to concentrate on development, not to mention that many times you miss the long-awaited event because you are busy looking for the 'yes' button to resume debugging or force a variable. Does anyone know how to disable the confirmation messages?

Post by edvard-munch on How I can get "Done flag" for "Modbus Slave Channel"? ^{CODESYS Forge talk (Post)}
This is from 10 years ago, I know. But I have been using (SLAVE_DEVICE.iChannelIndex = CHANNEL_NUMBER) AND (SLAVE_DEVICE.xDone) I suppose that it shows xDone for the channel that shows up in the iChannelIndex at the same cycle? It seems to be working properly for two devices that I have been using it before But now I have another device and using two write channels, for one register each. One channel works properly and returns DONE flag When another channel is triggered, I see that it shows up in iChannelIndex, but flag DONE not received, but no Error for the channel. Also, when i check the register in the device it's evident that data has been transferred. Is this could happen sometimes with CODESYS, so DONE flag not received? Or this is a problem with a given device? With this certain register
