Post by timvh on Unable to select VisuDialogs.Numpad in Open Dialog input configuration ^{CODESYS Forge talk (Post)}
You should not use the "open dialog" to change the value. Instead use the input configuration "Write Variable" to change a variable value in the visualization. in the setting of this input command, you can choose the Input type (select dialog).

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Ok, think I understand. The reason for the error is I try to include complex variables (FB) in the persistenced data. I will try to use {attribute 'ac_persist_exclude'} to exclude those elements.

With reference to the release note for "CODESYS Recipe..." from CoDeSys (https://www.codesys.com/ecosystem/release-lifecycle/releases-updates/recipes/). After updating that software module to v4.6.0.0 on CoDeSys 3.5.21.1 I am no longer able to reproduce the problem.

Thanks for the update, Since you can't double click is there another way to enter the FB when online and see the running code of that instance? When can we expect to see v1.0?

see here: Visualization Support | V 4.3.1.0 will be released on 14.02.2024 https://de.codesys.com/das-system/releases-updates-lifecycle/release-plan-roadmap.html so you need to update by CODESYS Installer to that version as soon it is available.

Post by timvh on Missing Font ^{CODESYS Forge talk (Post)}
Not sure, but maybe it related to the style. Go to the Visualization Manager in your project and see if a style is selected, or choose another style to see if this helps.

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.

Post by tvm on Timer On Vijeo ^{CODESYS Forge talk (Post)}
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

Post by hwopereis on SFC Action problems ^{CODESYS Forge talk (Post)}
Only logged in to agree with the above. So counter intuitive. Why does an associated action force the variable when the step it is associated to is not active? Makes no sense at all, is terrible to debug and costs a lot of time. Such as shame.

The help says VAR_GENERIC exists, but trying to use it in 3.5.21.30 results in a unknown token error. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_vartypes_var_generic_constant.html Did this feature get removed or is there something else that needs to be done to enable using generic function blocks?

Post by timvh on Access Violation sherd memory ^{CODESYS Forge talk (Post)}
Maybe it is better to use Interfaces to access the objects instead of pointers. But besides that, is "read_obj_ptr" a method? If yes, you need to call it, so add brackets behind the method call: read_obj_ptr();
