6.13 - PROFILE
16 different profile sources can be configured in the device and used for
different purposes. Profile sources can be assigned as external set source
for PID channels in the device. Profile sources can be transmitted to other
systems as reference sources using analog outputs.
By defining 10 different process curves, these curves can be used in the
desired number of repetitions for the profiles (
