S DP master, class 2 (DPMC2):
Devices to configure, commission and for operator control and monitoring
during bus operation.
Examples: Programming units, operator control and visualization devices
2. Slaves (passive devices)
These devices may only receive and acknowledge messages, and on request
of the master transmit messages to these devices.
Examples: Drives, I/O modules etc.
PROFIsafe
For PROFIsafe, it involves a PROFIBUS profile for fail-safe data transfer between
fail-safe components (F master and F slave) along PROFIBUS DP.
The PROFIsafe profile is characterized by the fact that the safety-relevant func-
tions are implemented in the safe terminal nodes, i.e. the F/CPUs, the distributed
slaves and the actuators/sensors/field devices using the standard PROFIBUS
functions.
The useful (net) data of the safety function plus the safety measures are sent in a
standard data telegram. This does not require any additional hardware compo-
nents, since the protocol chips, drivers, repeaters, cables can still be used as they
are. This means that both standard components and F components can be used
on a PROFIBUS system.
