HLI library memory interface to the ISG-MCE

The user library hli.lib is one of the components of the ISG-MCP. It contains the definition of the memory interface HLI to the ISG-MCE. Through this interface, the PLCopen FB send the motion commands for their assigned axes and receive ISG-MCE messages with respect to their axis.

In the TwinCAT environment a PLC application has to call an instance of MCV_HliInterface firstly to initialize the global pointer for HLI access ( see application Frame_PLCopenP1.pro]). After successful initialization programs and function blocks of the described user libraries may be used.
