Post by niloufar on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Hi, Our program incorporates various function blocks and programs written in different languages such as St and SFC. They implement numerous actions and methods using different languages from their function blocks. My question is whether the execution order of function blocks is associated with the programming languages used. I understand that cycle time can be configured in the task configuration, but I'm curious if there is a specific sequence order of execution for function blocks written in different languages. For example, all function blocks in (ST) are executed first, followed by the execution of (SFC). Specifically, when the function is written in (ST) and the action is implemented in (SFC). I modified all function blocks in the main PLC program and configured a task configuration for the main program.

Hi, will check the CodeSys function blocks. Didn't know those and usually the OSCAT lib is a bit more advanced. Kind regards!!

Post by ellocco on FUP: Ausgang eines existierenden Blocks mit dem Eingang eines existierenden Block verbinden ^{CODESYS Forge talk (Post)}
Ist es unter dem FUP-Editor von CODESYS V3.5 SP18 möglich, eine Leitungsverzweigung mit einem existierenden Block (z.B. AND-Glied) zu verbinden? Oder den Ausgang eines existierenden Blocks mit dem Eingang eines existierenden Blocks (z.B. OR-Block) zu verbinden? Gibt es dazu Vorschläge?

One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello jacobwago, I believe that the limit is fixed in the editor, but not in the driver package. There seems to be no link between the driver setting and the editor. Otherwise, I don't know why the input (>10) is blocked, but the function is available. Unfortunately, I cannot offer you any other solution apart from the one mentioned above. Kind regards
