Loss of the safety function through changes to the system.
Can Cause Death, Serious Injury, or Property Damage.
To ensure the safety of the system, any changes to it or any replacement of defective
components must be followed by a thorough and successfully completed function test of the
system.
A complete function test consists of the following tests:
• Configuration test (test of the configuration)
• System test (wiring test of the connected sensors and actuators)
Loss of the safety function.
Can Cause Death, Serious Injury, or Property Damage.
Test interval for safe AS-i input slaves
The calculated failure probabilities for safe transmission of AS-i input slaves is based on an
actuation interval of one year.
For this reason, all sensors that are recorded using safety-related AS-i input slaves must be
actuated at least once every 12 months in order to test their function.
If the mechanism of the safety-related AS-i input slaves is used for direct data exchange, a
corresponding signal change must also take place here at least once every 12 months, same as
for the safety-related AS-i input slaves.
