Definition of PROFIBUS DP

PROFIBUS DP is an international, open field bus standard specified in the European field bus Standard EN 50170 Part 2. PROFIBUS DP is optimized for high-speed, time-sensitive data transfer at field level.

Components communicating on PROFIBUS DP are classified as master and slave components.

Master (active bus node)

Components representing a bus master determine the data traffic on the bus and are therefore also referred to as active bus nodes.

Slaves (passive bus nodes)

These devices may only receive, acknowledge and return messages to the master if requested by the master.

Examples: SINAMICS drives, I/O modules

Note

If a SIMOTION D410 DP is operated as a passive PROFIBUS I-slave, the display, measuring functions and controller optimization engineering functions will be very slow. If possible, use the "active I-slave" setting for local commissioning (which does mean that an equidistance is no longer possible) and for complete commissioning, switch to "passive I- slave".

You will find additional information about PROFIBUS DP in the SIMOTION Communication System Manual.
