6.3 OPTION: PNO Encoder Profile, safety instrumented
(Safety BP/XP (PNO))
With this configuration, as with a non-safety-related communication, the measuring system supports
the PNO Encoder Profile (Profile-ID 0x3D00) defined by the PROFIBUS User Organization
according to Version 4.2. Two additional encoder classes have been defined for safety-related
PROFIsafe communication:
● Encoder Class S1:
Standard safety-instrumented measuring system with safe position data and preset functionality.
The isochronous mode is not supported.
● Encoder Class S2:
Standard safety-instrumented measuring system (Class S1) with additional safe velocity data. The
isochronous mode is not supported either.
The F-status byte Safe Status or F-Control Byte Safe Control contained in the
F_MessageTrailer (process data) is contained in all safety-instrumented
submodules (Telegram 36 (BP/XP) and Telegram 37 (BP / XP)) and is described only
once in Chapter 6.7 from Page 132.
6.3.1 Structure of the cyclic process data
For the configuration of the cyclic data exchange, a series of safety-related (F) standard signals is
available for the PROFIsafe communication:
