Safety PLC AC31-S - Safety First
Nowadays, machine and plant manufacturers are con-
fronted by ever more extensive and ever more stringent
safety conditions, in line with the demand that the safety
of machines and systems must be implemented optimally
and in line with the “state of the art” for protection of man,
machine and the environment. The safety-related au to-
mation system AC31-S allows small, distributed control
units to be designed and standardised. They operate
autonomously at a local level where the safety function
is required. The relevant, related inputs and outputs are
installed in the field where the signal is detected or output.
They are connected to their central unit via the AC31 Safety
Fieldbus. This helps, once again, to save on cables. These
control units can be networked flexibly and can exchange
data among each other or with a higher-level system.
Economical
The Advant Controller 31-S requires no redundant
central unit for safety functions, so this system is lowcost
both as regards hardware and as regards engineering.
The I/O units at a local level already feature an internal
2-channel structure and monitor themselves, including
passive error and fault detection.
One set of hardware for all functions
The hardware of the Advant Controller 31-S supports
the safety functions and operating functions si multaneous-
ly. At the AC31 safety filed bus safety-related I/O modules
and standard I/Os can be mixed.
The safety-related functions are programmed with the
help of certified function blocks.
The controller is certified for requirement class 4 and
safety categorie 3.
