13.9. PROFIsafe data bytes (data block for safe functions)
Safe PROFIsafe data are transmitted in addition to the non-safety-related PROFINET data. These data include all information
about the door position and guard locking, emergency stop and enabling switch, for example.
Important!
This device can be operated either in the “standard” or in the “expanded” configuration. Additional
functions are available in the “expanded” configuration (see chapter
13.7.3. Additional button functions
(only for configuration with expanded data structure) on page 26
Select one of the configurations by bringing together the corresponding modules via drag & drop in
the configuration software of your control system.
The modules are easy to distinguish with the aid of the comment block. Plug-in standard modules
and expanded modules must not be mixed. The modules must be selected before the first Power On
process. Another Power On process is necessary in case of exchanging.
13.9.1. “Standard” PROFIsafe data bytes
The “standard” PROFIsafe data block includes all safe functions. It is subdivided as follows:
Ì
2 input bytes of data for the functions (e.g. emergency stop switch position)
Ì
2 additional input bytes (empty)
Ì
4 input bytes used within PROFIsafe
Ì
1 output byte for the functions (e.g. safe control of guard locking)
Ì
1 additional output byte (empty)
Ì
4 output bytes used within PROFIsafe
All data bits are present in parallel in the non-safety-related PROFINET and can be used as signaling bits there.
Important!
Never use the signaling bits for safety functions.
