<strong>PROFIBUS</strong> parts<br />
Physical layer<br />
• Originally RS 485 or fibre optics, today others (RS 485‐IS, MBP)<br />
Link layer<br />
• Frame coding, medium access, error resolution (CRC, repetition)<br />
Protocol parts<br />
• <strong>PROFIBUS</strong> FMS –the oldesT, communication between PLCs<br />
• <strong>PROFIBUS</strong> <strong>DP</strong> –data exchange between PLC <strong>and</strong> remote IO,<br />
well known, functional enhancements (<strong>DP</strong>‐V1, <strong>DP</strong>‐V2)<br />
