The actual pressure of about .04 psi (in this case) can now be
read directly.

Messages to PLC-5s and
CLX to Get Data from CN2FF
You can use a ControlNet message instruction to get any of the data
that is stored in the different tables that list the various ControlNet
objects.
For a CLX to retrieve data, setup the message as shown below.
For a PLC-5 to retrieve data, setup the message as shown in Figure F.7.
TIP
The best way to get data from a CN2FF into a
controller is to have it produced by the CN2FF.
This requires that you use RSNetworx to
schedule the data. It is much more efficient than
using message commands.
