3.5.3 PROFIBUS DP Communication
3.5.3.1 Overview
MD580–SI‑DP1, a PROFIBUS‑DP fieldbus adapter module, must be used with the
MD580 AC drive of Inovance and fixed in the extension slot (CN13 slot) of the AC drive.
It communicates with the bus master using the PROFIBUS‑DP communication
protocol.
Features:
● Automatically identifies the bus baud rate; supports the communication rate
ranges of 9.6 kbps to 12 Mbps.
● In the bus topology, connects up to 32 nodes (including the master) when no
repeater is used, or up to 122 nodes when repeaters are used (each segment
comprising 31 nodes and one repeater).
● Complies with the EMS standard EN 61800‑3:2004.
● Supports DPV0 and DPV1 for data exchange with the master.
● Be powered by the AC drive, without requiring an external power supply.
