Another way to resolve this is to set Codesys to use a specific version of the offending library under Placeholders in the Library Manager.

Post by ton on How to create a stopwatch? ^{CODESYS Forge talk (Post)}
Hi, i guess you want to make a hour counter. You need to store the measured value. Try to use a retain variable, but need a graceful shutdown, or save it your self. see https://forge.codesys.com/forge/talk/Runtime/thread/278e325579/ Succes.

Hey mate, did you get to the bottom of this? If not, have you double checked the buttons are linked to the correct variables and/or performing the correct action? Have you tried always enabling the block to confirm false is moved to the variable if so?

Maybe also good to know that you could use the CODESYS installer to switch between gateways. - open the CODESYS installer - Select the (hamburger) menu - Select Settings - Select Services Then select the Gateway you would like to use.
