1)
Triggering by the internal solenoid valve/
forced venting is only active when an inter-
nal solenoid valve/forced venting is installed
in the positioner. See 'Internal solenoid
valve/forced venting' reading (Code 45).
The measured values are included in the trig-
gered data logging when one of the condi-
tions defined in 'Start trigger via internal so-
lenoid valve/forced venting' or 'Start trigger
via set point' are met.

Positioners can be optionally fitted with a bi-
nary input. Triggering by the binary input is
only active when the positioner is fitted with
a binary input.
The measured values are included in the trig-
gered data logging when the state of the bi-
nary input changes.
