Hello, I'm trying to use FILE.Open to open file that exists in the given location. sFileName is formed from "Copy as path" in Windows. So I'm sure file exists and it is in the given location. And still, I get thiss denied error. What could be the problem here? Attached is a screenshot with current implementation.

Hello, what would be the most efficient way to check whether the file exists or not. I don't want to use file.Open function, it seems like rather inefficiet operaton. I considered GetAttribute function, but this function doesn't accept filename (with path) as an input. Basically I need to check first time when program is loaded to the runtime i.e. when application is started for the first time, whether a file exists on the specific location or not.

Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved

Do you think there'd be a way to turn this into a library? How would I2C_master be passed down to POU FBs?

We've been experiencing an issue through SP18, SP19 and now SP20 where the Persistence Variables do not retain if we upload our program via a Boot Application. If we use the exact same program, and perform a Direct Upload via the Laptop and Ethernet connection, the Persistence Variables work exactly as expected. I have submitted 2 bug support tickets but I haven't had a response back from Codesys. Has anybody experienced the same issues and discovered a workaround? We have a requirement to utilise...
