SYSTEM SYNCHRONIZATION (S7999D OI
DISPLAY ONLY)
The user can manually synchronize conguration data from the
connected controls at any time.
A new control is visible when conguration and status data is
gathered from it. This collection procedure takes a few minutes.
The control is marked as “Unknown” when no conguration
information exists. Normally, control conguration data collection
only needs to be performed when the control is initially installed.
However, a re synchronization is necessary after the OI Display
is reset. See Figure 54.
The user presses the Synchronize button to begin synchronization
with the control.
Status of the synchronization is reected in the dialog box. The
synchronization can be aborted by selecting the Cancel button.
