C-DIAS SAFETY DIGITAL OUTPUT MODULE CSTO 082
1.5 Page 7
The minimum system of a safety-related control with the CSTO 082, as shown above, is
formed with a C-IPC a CMB 081 and a Safety CPU or type CSCP 012 for example.
The safety-related application is found in the Safety CPU after configuration and can run
independently of the C-IPC. The C-IPC, however, is required to power the bus correctly
and cannot be removed. In addition, it is also needed to establish the communication be-
tween the Safety CPU and the design tool (SafetyDesigner).
On the C-IPC and coupler modules, connectors are provided over which the C-DIAS bus
must be externally supplied with a voltage of 24 V. The external supply for the output and
clock drivers should be independent of the external C-DIAS bus supply (see below)
With the help from an SD card with a valid configuration, the Safety CPU can also be con-
figured independently of the design tool (SafetyDesigner). More information can be found
in the Safety CPU handbook under the chapter "Handling the micro SD card". With regard
to the configuration using the design tool, the SafetyDesign handbook must be consulted.
