Hi, Is it possible to enable/disable software modules at runtime? Like this but at runtime. [image]

In case you want to do it manually via AS and not pro grammatically, you also can do that during runtime: Go To “Online”->“Compare”->“Software” and use the context menu on the program you want to stop on the right side. [image]

Hi @alexander.hefner thank you for the help I will try that. @Stefan_Hirschen could be a simpler solution. Is it possible to do the same but using the runtime utility center? Thanks again for the help.

Regarding the ST_tmp_suspend() and ST_tmp_resume() I’m unable to compile the B&Rs example, it’s as if I’ve not added the library. Would you happen to have any idea what the could will be the problem? string1:='teste'; status_id := ST_ident(ADR(string1), 0, ADR(ident)); IF (status_id <> 0) THEN …

Hi, the sample is based on the function calls without “tmp” in the function name: those are legacy functions not usable with actual systems. You have to replace those calls with the functions containing the “tmp” in the function name, so please use “ST_tmp_suspend” and “ST_tmp_resume” instead of “…

Everything is working now, but after a reboot, the task starts again automatically, which I don’t want. I need the task to start only when I explicitly call the function.

Hi, yes, it’s like you’ve described. The actual systems (Intel and ARM based) only support the temporary suspending / resuming of tasks, a non-volatile suspending is not supported. I solved it in my projects by suspending the wanted tasks every boot via the function call inside the INIT program, a…

Hi @alexander.hefner , I tried your solution and it works great. Thanks for the help.

Hi,

yes, by using the function blocks ST_tmp_suspend() and ST_tmp_resume() from the sys_lib library.

Best regards!
