Chapter 2 The AADvance Safety Controller
is an output configured to go to a specific value, or configured to hold last
state)
Safety System Certification The AADvance Controller is certified by independent certifying bodies. Refer
to the certificate for details of the standards included in the certification.

Specifications
Scan Times
The controller processing scan times listed in the table are taken from a test
system which used only production modules. The tests which were used to
measure the scan times did not measure the effects of logic complexity and
communications loading.
