SCADAPack Controllers

What values are stored in the Primary, Secondary and Tertiary registers for each field unit type?

Please note that not all field unit types use all three process output values, depending on the type of field unit.

In general, the units for each field unit are fixed, despite the fact that you can change the units being displayed on the field unit display or in Accutech Manager. The exceptions to this are the DP10/DP20, the GL10 and the SL10, which can be used to measure different values such as Flow, Level or Pressure.
