Post by nathant on Saving variable values on power cycle (RevPi Connect) ^{CODESYS Forge talk (Post)}
Hello, this seems to be a known issue, but persistent/retain variables don't seem to work properly on RevPi devices. Is there a workaround to this? All I need is for a few configuration variables to be remembered through power cycle.

First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

Open the CODESYS Installer (from the menu Tools). Go to Browse. Search for: help ... Select the CODESYS Offline Help which you would like to install. (probably you have to close CODESYS to install it and reopen it after installation).

Resolved this. There is a config file called CodesysControl_User that I had to edit to set the driver to component 5. I deleted the semi colon next to Component.5=CmpEt1000Drv

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.
