Fig. 27. Diagnostic page (digital I/O).
The control analog I/O can also be viewed on the OI Display.
A snapshot of the diagnostic status is displayed and updated
as it changes in the control.
The analog I/O data is displayed as bar charts with I/O level
represented in the I/O range (see Fig. 28) Analog I/O that is
not enabled for the installation displays a blank I/O level. Not
all analog I/O can be displayed at the same time on the page,
so a horizontal scroll bar is used to move the view left and
right to show all analog I/O status.

System Configuration
The OI Display has some functions related to general
configuration for the control in the end user installation.
Pressing the Display Refresh button invokes a search
procedure. A new R7910 Hydronic Control or R7911 Steam
Control is identified by "Unknown" status next to its name in
the boiler system list (see Fig. 29). "Unknown" indicates that
configuration data has not been retrieved from the control yet.
Fig. 29. System refresh and synchronize screen.
The control connected to the Modbus network is indicated to
the user after the search procedure has concluded.
Once the control is located it must be synchronized with the
OI Display before it can be displayed. New controls are not
displayed on the Home page until this synchronization (see
below) is performed.
System Synchronization
The user can manually synchronize configuration data from
the connected controls at any time.
A new control is visible when configuration and status data is
gathered from it. This collection procedure takes a few
minutes. The control is marked as "Unknown" when no
configuration information exists. Normally, control
configuration 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.
The user presses the Synchronize button to begin
synchronization with the control. See Fig. 29.
Configuration
The SOLA Control can be configured from the OI Display. The
control configuration is grouped into the functional groups
seen in Table 4.
