Linking into the System Manager
The library has one input structure: ST_Parameter_IN, and one output structure: ST_Parameter_OUT. These must be instanced and addressed, so that on the one hand they can be passed to the FB_ParameterControl function block as VAR_IN_OUT, and on the other hand can be linked into the System Manager. The terminals' process data contains 6 or 16 bytes, depending on which ASI module is linked into the System Manager. These can be linked directly.
