Depending on the F system, select the interface module for ET 200S as follows:
Table 1-1
Interface module
IM151-1 HIGH FEATURE *
for PROFIBUS DP
connection
IM 151-7 F-CPU ** for
PROFIBUS DP connection
IM 151-3 PN HIGH
FEATURE for
PROFINET IO connection
*: V1.1.1 or higher for use with PM-E F pp DC24V PROFIsafe power module
**: V2.0.6 or higher for use with PM-E F pp DC24V PROFIsafe power module
The IM151-1 HIGH FEATURE and the IM 151-3 PN HIGH FEATURE are described in the
ET 200S Distributed I/O System
product information bulletin.
Use in Safety Mode Only
Fail-safe modules can only be used in safety mode. They cannot be used in standard mode.
Achievable Safety Classes
Fail-safe modules are equipped with integrated safety functions for safety mode.
The following safety classes can be achieved in safety mode by assigning appropriate
parameters to the safety functions in
optional package, by combining certain standard and F-modules and by arranging the wiring
of the sensors and actuators in a specific way:
