4.3 Configuring the PROFIBUS DP interface (only D410 DP)
4.3.1 General information about PROFIBUS DP communication
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".
