￭ PLCs
For example, the following controller stations are supported:
• ABB AC500-S Safety PLC
• Siemens SIMATIC Fail-safe S7 PLC
Note:
Other PLCs which support PROFIsafe over PROFINET can also be used with FSPS-21.
￭ Protocol
The FSPS-21 module is compatible with Ethernet standards IEEE 802.3 and IEE 802.3u
and it supports the PROFINET IO protocol.
All PROFINET IO masters that support:
• GSDML file version 2.33
• PROFINET IO protocol according to IEC standards 61158 and 61784
• PROFINET IO conformance class B
are compatible with the PROFINET IO module. FSPS-21 module supports PROFIsafe
version V2 (IEC 61784-3-3).
Supported safety functions
This manual provides instructions for creating and using these safety functions (according
to EN/IEC 61800-5-2):
• Safe torque off (STO)
• Safe stop 1 (SS1-t)
Target audience
The manual is intended for qualified persons who design the safety application, plan the
installation as well as install and commission the safety application. Read the manual before
starting work on the safety application. You must know the fundamentals of safety technology,
electricity, wiring, electrical components and electrical schematic symbols.
Purpose of the manual
The manual explains how to install the FSPS-21 module and configure and commission the
supported safety functions. It describes how to meet and maintain safety life cycle
requirements of the FSPS-21 module to ensure required safety performance and specified
safety integrity.
Recommended reading
This manual is based on the following standards. It is recommended that you are familiar
with these standards before implementing safety-related systems.
• EN/IEC 61800-5-2: Adjustable speed electrical power drive systems – Part 5-2: Safety
requirements – Functional. (Includes safety function definitions.)
• EN ISO 13849-1: Safety of machinery – Safety-related parts of control systems – Part
1: General principles for design
