Accessing Tags from an assembly (dll)

Post by andis59 »

I have an iX project that uses an assembly (dll) to communicate with an external device. To do this I need values from the PLC, which are in some Tags.

Is there someway to access these Tags from the assembly/dll?

I need both read and write access.

If you know the functions within the dll you can import them into your application using;

private extern static uint SetSystemTime(ref SYSTEMTIME lpSystemTime);

SetSystemTime is now your function to call the SYSTEMTIME function in the coredll.dll.

This only works if the dll is documented so you know what the functions are inside it.
