Post by orbis-tertius on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Is there anybody can help me with the same problem? I have to migrate created project in ver.3.5.17.0 32BIT with runtime 4.7.0 to ver.3.5.20.0 64BIT with runtime 4.7.11.0 due to the new license. All the libraries and dependencies are updaded and there are no any errors. The first compilation and loading to the controller is being compleated well. After this being done and if I am forced to change any values or change any code in the current project, another compilation will be freezed. This problem can be solved if pressed Build/cleen or cleen all. There is another method to solve this; if project is loaded with excluded object (Alarm Configuration), repeated compilations will be done well.

Post by fajean on Issues with "Add all instance path" ^{CODESYS Forge talk (Post)}
In the past, we have routinely used the "add all instance paths" function to automatically add variables to VAR_CONFIG lists. My recollection is that compiling a project did not require VAR_CONFIG to be fully populated, and, once successfully compiled, instance paths could be added. Errors related to missing declarations, if I recall correctly, were thrown when downloading to the PLC, they did not prevent a successful compile. At some point, it stopped working. Missing declarations in a VAR_CONFIG now cause a compile error, so the application is never "current", the only reason I can see being the missing VAR_CONFIG declarations themselves (no other error). We observe the same behavior across all our projects. This is really aggravating, and I must be missing something simple. We use 3.5 SP17p3, 64 bits. Can anyone help?

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something? I am using a Groov Epic PR1, my software version is 3.5 SP19 Patch 5 32 Bit.

Post by tayhim on WAGO HMI Device not found ^{CODESYS Forge talk (Post)}
Hello, I'm trying to connect with a Wago TP600 HMI but without success. I'm using codysis 3.5 SP19 patch 7 (SP20 block all the time) and the official wago package is installed. However, when I scan and select my device, I get a message saying that the device doesn't match the project's device object with the possibility to update the device (as shown in the attached picture). however, after choosing to update i got a message that the device is not found. I've tried with a new empty project but the same results. do you have any ideas? Thanks.
