S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
19 65-0303—05
Diagnostics Button
The Diagnostics button displays analog and digital I/O status of
the SOLA Control. A snapshot of the diagnostic status is
displayed and updated once per second as it changes in the
control. See “R7910A or R7911 Diagnostics” on page 44 for
more information about this status.
The digital I/O data is displayed as LEDs that are either on
(green) or off (red) (See Fig. 23). Not all digital 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 digital
I/O data.
Fig. 32. 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 Figure 24.) 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
(S7999B OI DisplayOnly)
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 (see Fig. 34). A new R7910A Hydronic Control or
R7911 Steam Control is identified by “Unknown” status next to
its name in the boiler system list (see Fig. 35). “Unknown”
indicates that configuration data has not been retrieved from
the control yet.

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
(S7999B OI Display Only)
The user can manually synchronize configuration data from the
connected controls at any time.
