3.7 Connection examples
WARNING!
Warning against personal and property damage!
The use of the connection examples described in this section alone is not
enough to execute the safety function according to the SIL, Cat./PL deter-
mined from the risk analysis. In connection with safe devices, sensors
and actuators, additional measures may be necessary to ensure the
safety function. This includes, for example, the appropriate wiring and
parameterization of digital inputs and outputs, as well as measures to
exclude unforeseeable errors.
More information is available in the user manuals of the safe devices
used.
The section generally describes possible applications, in which the functions of the
System SLIO safety module for implementation of a safety function are used. You can
only use the depicted connection examples in a tangible safety application after a per-
formed risk analysis.
CAUTION!
Please consider at single-channel operation!
At single-channel operation the demand rate of the safety functions is
max. 1/100 of the test rate!
n
System SLIO safety input
–
The test rate for the System SLIO safety input module at single-channel operation
is 1x per 150ms. This means the max. demand rate is 1x per 15s.
–
You have to evaluate the external components, which are used in single-channel
operation, regarding the demand rate (e.g.: manual check of a single-channel pro-
tection door switch).
n
System SLIO safety output
–
In single-channel operation each output-channel of the System SLIO safety
output module internally exists twice (serial redundant). Therefore, the require-
ment with regard to the demand rate is not applicable.
–
But you have to evaluate the external components, regarding the demand rate,
which are used in single-channel operation.
CAUTION!
Please note for 1-channel operation of the safety output module!
With 1-channel operation according to Cat.2 / PL d of the safety output
module, the user program must always react in the event of a diagnostic
so that a safe state is initiated. This must be ensured by the application
and can not be realized by the safety module itself.
