C-DIAS Safety CPU
CSCP 012
Module Description
The Safety CPU component series has the safety integrity
level SIL3 and/or SIL CL 3 according to IEC 62061 and/or
Performance level e (PL e) according to EN ISO 13849.
The Safety CPU component series has:
4 safe inputs (IEC/EN 61131)
2 safe outputs (IEC/EN 61131)
The safety in- and outputs are used for the safety-related
reading of 4 input channels or 2 double-channel sensor
signals (emergency stop, confirmation button etc.) and the
safety-related output of 2 actuator signals to, for example,
control relays, valve, etc.

The Safety CPU module CSCP 012 is suited for use in systems with optional modules and
interface variables in accordance with the system hand book version 1.5, sections 1.6, 7.1
and 7.2.
The Safety CPU module has 2 non-safety signal outputs, TA and TB, to test inputs and
detect cross-circuit faults (i.e. emergency stop).
The CPU module alone is already a minimal system of a safety control. A practical exam-
ple is given later in this handbook.
In addition, the Safety CPU regulates the synchronized communication with the remote
Safety modules through safe bus telegrams. Among their jobs are:
•
Processing the safe application and
•
The distribution of configuration data to remote Safety modules.
When wiring, it is important to note that the output supply of the Safety outputs is
not protected against polarity reversal.
If the polarity wired in reverse, the Safety module must be exchanged and sent for
repair.
