CONFIGURATION
4.1 OVERVIEW
The Compound Gallery in the ViZApp (Visual Application Builder) software includes a
compound called PID_OH. This section explains how to configure MOD 30ML or Modcell
using this compound for use with the Output Holder. The purpose of this compound is to
cause the control loop to synchronize its output holder before turning its field output on. This
will in turn cause a bump less transfer. This happens only when the controller first initializes
at power up.
4.2 LOADING THE COMPOUND FOR MOD 30ML
The PID_OH compound has a fully functional PID, with I/O, Display, Tuning List and also the
logic for bumpless transfer of output.

If you already have your PID configured, you can delete the blocks that are not required from
this compound after loading.
1. Launch the ViZapp Software and open your workspace, project and the instrument
database.
2. The PID_OH compound can only be loaded inside a loop compound. Open the loop
compound where you want to load the PID_OH compound.
3. Select Project – Gallery – Component Gallery from the menu bar as shown in the
figure below:
