Contact the equipment manufacturer directly to determine the way that soft signals are exchanged, for the protocol varies from make to make.

Look at the project-specific I/O lists and respective schematic drawings to determine the hard signals.

If you are new to this, order a small PLC and a modest HMI to build a practice application, that will make clear for you the concepts of hardwired and soft signals, and what memory mapping is, meanwhile read this document.
