Connection Examples for Safe Outputs
7.1
Explanation of the Examples
Depending on the type of wiring, the outputs of a module can achieve different
safety integrity levels (SIL, SIL CL, Cat., PL) at the same time (as long as the
settings do not contradict one another).
The following examples only describe the options for the electrical connection of
controlled devices/actuators to the safe outputs.
Should you have any questions regarding applications to be implemented, please
contact the Bosch Rexroth safety hotline (see
The following are specified for each example:
•
Basic specifications
The main data for the example is specified in the table.
•
Device diagnostics and behavior of the module in the event of an error
Diagnostic capability depends on the parameterization.
If a message is transmitted to the safe controller in the event of an error, the
message is specified in the tables. For information about the relevant error
code, possible remedies, and information about whether acknowledgment is
required, please refer to
Chapter “Errors: Messages and Removal” on
•
Typical parameterization
The table illustrates an example of all the parameters for the specified
assignment.
Key for all tables in this section:
Errors (cross circuits, short circuits), which can be prevented by correct installation
(e.g., protected cable installation, isolated cable installation, double insulation, use
of ferrules) are not described in the following tables.
Therefore, for example, only errors between outputs, which are on the same con-
nector, are described. For example, in the event of correct installation, cross cir-
cuits with outputs of other connectors cannot occur.

Parameterization tables
For all examples, please also observe the measures specified in the
individual tables, which must be taken to achieve the specified
SIL/SIL CL/Cat./PL and all measures according to standards EN
61508, EN 62061, and EN ISO 13849-1 to achieve the specified
SIL/SIL CL/Cat./PL.
