Post by timvh on Codesys 3.5.18.60 – Application Loss and Persistent Data Corruption ^{CODESYS Forge talk (Post)}
Which device do you use? Does this have persistent memory (e.g. NVRAM) available? Maybe first ask your PLC vendor about the possibilities and how they advice to use persistent variables? If you have no NVRAM available, CODESYS will store the variables in a file when the device gracefully shuts down. But on an abrupt power failure, this is not possible. If you have no NVRAM and you want to use persistent variables, then consider using a UPS. In this case when the power is lost, the UPS can keep the power on the PLC which then can gracefully shut down. Alternatively use the Persistence Manager to store the variable values in a file e.g. only on change. See: https://content.helpme-codesys.com/en/CODESYS%20Application%20Composer/ac_pm_overview.html

Post by matthew on New Ladder Diagram conversion does not work due to missing features ^{CODESYS Forge talk (Post)}
Hi It looks like in the new ladder there is no way to remove unused FB call parameters or update the function block? It's quite often where you have a function block with multiple uses and not all the parameters are required. Need the ability to leave an input/output blank without getting an compile error Expression expected instead of '' Also double clicking on the FB no longer opens the underlying FB code and view what it was doing online. Dragging and dropping a variable does not work, only using the selection works. Will these be available in the V1.0 release or just best to stick to the old ladder until it's available? Thanks

Post by pethun on Upgrade from codesys 3.5.19 to 3.5.20 ^{CODESYS Forge talk (Post)}
Hi We upgraded our ptoject from 3.5.19 to 3.5.20 but we get an error message in the latest version. We made our own trend function and its related to this we get error message: Trend_Menu Device: PLC Logic: Application: C0032: Cannot convert type 'RTS_SYSTIMEDATE(systimertc, 3.5.20.0 (system))' to type 'RTS_SYSTIMEDATE(systimertc, 3.5.17.0 (system))' The variables are defined as follow: start : SysTimeRtc.SYSTIMEDATE; end : SysTimeRtc.SYSTIMEDATE; The code that creates the error is the variable start and end IF xAssign THEN xAssign := FALSE; xPanEnable := FALSE; xZoomEnable := FALSE; drs.liFrom := VisuTrendStorageAccess.TrendStorageConvertToTimestamp(start, 0 (us)); drs.liTo := VisuTrendStorageAccess.TrendStorageConvertToTimestamp(end, 0 (us)); drs.m_itfDateRangeSelectorClient.SetCurrentRange(drs.liFrom, drs.liTo); END_IF I cant understand really what the error message means and what can be the cause of the error? It compiles fine in dthe older codesys 3.5.19. If anyone has some experience of this please help us out? We must upgrade due to the new licenses. Thanks
