Using the fail-safe power module PM E F pp DC24V PROFIsafe
Using the fail-safe power module PM E F pp DC24V PROFIsafe is only possible:
● As of order number 6ES7151-1BA01-0AB0, Firmware version V1.1.1 or higher
● As of order number 6ES7151-7FA01-0AB0, Firmware version V2.1.4 or higher
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
STEP 7
with the
S7 Distributed Safety
or
S7 F Systems
optional package, by combining certain standard and F-modules and by arranging the wiring
of the sensors and actuators in a specific way:
