PROFIsafe message
One bit of the PROFIsafe data is always used to control specific safety functions.
• The structure of the PROFIsafe data is described in the PROFIsafe profile.
• The length of the PROFIsafe message in the SM301 is 8 bytes (fix).
• In the following subchapters, the meaning of the PROFIsafe process data is separately described
for PROFIsafe output data and PROFIsafe input data.
Tip!
Detailed information on the PROFIsafe message can be found in the manual for the safety
module and in the PROFIBUS or PROFINET communication manual (
PROFINET is supported
from SM301 V1.1
).
