UNCTIONAL SAFETY
This chapter describes parameters in relation to functional safety. In accordance with IEC
61508, safety means first of all, that a system is free of unwarranted risks. Functional
safety is the part of the overall safety, which ensures that a safety system's response to
its input conditions is free of errors. Internal safety-related device errors must be detected
and brought into a safe condition in the process.
5.1 Safety-related parameters for an operation of 20 years
The following table lists the safety-related parameters of the Safety Module for an
operation of 20 years with an average environmental temperature of 70°C.
Safety-related parameters of local I/O terminals and decentralized components can be
found in the applicable documentation. The values in the following table relate exclusively
to the Safety Module.
In the identification values indicated below, the calculation to the following safe in-/outputs
is always contained.
m
CHAIN_IN
m
CHAIN_OUT
m
Output brake to the controller
m
Output pulse inhibit to the controller
m
Cycle output / cycle outputs
Minimum configuration:
Values are valid for the additional parameterization of:
1 x safe input / 1 x safe output
(additionally also e. g.:
m
DIG1_IN_1
m
DIG1_OUT_1
)
