1.2.3.1 Overview
The type designation of the safety module is E94AYAD.
Functions
ƒ Safe torque off (STO)
(previously: safe standstill, protection against unexpected start-up)
ƒ Safe stop 1 (SS1)
ƒ Connection of safety sensors
ƒ PROFIsafe safety bus connection
The SM300 supports the transmission of safe information on the PROFIsafe
protocol according to the specification ”PROFIsafe - Profile for Safety
Technology”, Version 1.30, of the PROFIBUS Nutzerorganisation (PNO). The
basic device transmits the PROFIsafe information to the SM300 for safe
evaluation.
The following applies to the SM300 safety module , version VA 1.xx:
ƒ The basic device must be equipped with a communication module
E94AYCPM (PROFIBUS-DP), SW version 0.9.
ƒ The safe parameter setting is not supported. For this reason, all
parameters are permanently set.
ƒ The stopping time of the SS1 cannot be parameterised. It is
permanently set to t
s
= 30 s.
ƒ This module does not support (safe) outputs.
