Hello, I have a problem with the errors "exception access violation" and "sourceposition". I have an FB_REST_API which has a Query method in which fbBasicAuthWebClient is called. This part works. Then I have an FB_MiR_Fleet_Comm which inherits from FB_REST_API. In FB_MiR_Fleet_Comm I create the Test1 method in which I call Query and errors appear here. Generally removing things from Test1 at some point the problem disappears, but based on that I am not able to deduce what is the problem :( FB1: FB_REST_API...

My idea was to create a simple interface for communication with devices via REST API. I wanted to create one general purpose function block for REST API communication, and then create function blocks that will inherit from the general one and contain methods for querying individual endpoints - for communication with specific devices from manufacturers. The intention was a minimum of parameterization. Basically I managed to execute the plan, but the methods are in the general FB_REST_API function...

It looks like this is possible for Schneider M241 PLC: https://www.youtube.com/watch?v=JGbnlcLvtJo

@eschwellinger Thanks for the great example. I think we are all interested in whether it is possible to log data using the "DataLogManager" module on an external memory such as USB / SD? It would be great if you could answer if there is such a possibility, and if so, please tell us how to set "DataLogManager" to write to external memory

Thank you i-campbell . I installed 32-bit IDE, but when I compiled project with this version of software there were more errors. And generally (don't know why) it was worse on 32-bit. I changed sysmem23 to SysMem as You suggested and it solved problem.

Hello, I get a build error that I do not understand how to resolve: C0338: The Library 'sysmem23, 3.5.13.0 (system)' is only supported in 32 bit applications The device is: CODESYS Control for Linux SL. Codesys version: CODESYS V3.5 SP16 Patch3 + (64-bit)
