7 Safe Fieldbuses

7.1 PROFIsafe

7.1.1 Introduction to PROFIsafe

This chapter describes the Advanced safety system when PROFIsafe is enabled and a PROFIsafe-capable fieldbus option board is
installed.
PROFIsafe is an additional safety protocol on top of a standard transmission system (PROFINET/PROFIBUS). PROFIsafe uses several
technologies to ensure the validity and status of the fieldbus communication, making it reliable to use with safety devices. These
measures include: consecutive numbering, watchdog time monitoring with acknowledgment, codename per communication rela-
tionship, and cyclic redundancy check for data integrity.
Communication over the non-safe transmission systems is called the "black channel".

The Advanced safety option board supports version V2.4 of PROFIsafe in V2 mode. The PROFIsafe protocol can be used in applica-
tions with up to SIL 3 requirements according to IEC 61508 and the PROFIsafe communication is implemented according to IEC
61784-3.
