A.4.3 Status signals via fieldbus – protocol FHPP
The motor controller has all the key information of the safety module (status, modes, errors, I/O). The
following information is primarily relevant for transfer of data to bus systems, in order to create a de­
tailed map of the system in a function controller:
– Common status messages on the status of the safety module (normal operation, safety function
requested, errors, etc. è Section 2.10.2).
– Status of the individual safety functions (Which have been requested? Which have been implemented?).
– Status of the digital inputs and outputs.
Below, the appropriate objects are listed for the FHPP communication protocol (Festo Handling and
Positioning), which contain information on the safety module.

0x0000 1000 Safety state reached (common message).
CAMC-G-S3: VOUT_SSR (VOUT 44) The bit is
set when, in the safety module, the safe state
has been reached for all the requested safety
functions.
CAMC-G-S1: STO active.
