Access to drivers of I/O cards:

Producers of input/output HW cards (Axiom, Advantech, ADlink, etc.) supply drivers for most HW cards for PC.

The drivers are DLL libraries for OS Windows in most cases, they are available on the Internet pages of the card producers and they are mostly free of charge. By means of the PmDll object it is possible to call functions of these DLL libraries, for example, read/write binary or analog signals, etc.

See Examples of calling functions in Dll libraries in the folder: /Pm/Examples/Others/PmDll.

Trade terms:

Using the PmDll object in the application is bound to the purchase of the PmDLL license. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
