The diagnostic bit in the cyclic process data makes it easy to find problems with the equipment.
It is possible to find problems with the equipment in real time using the cyclic (periodic)
data and to monitor such problems in detail with the noncyclic (aperiodic) data.

Flow control for each branch line
Can be used for the flow control, etc.,
of the main line and branch lines
The instantaneous flow, set value, and
accumulated value can be checked at
the same time.
