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 

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.

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. 

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.

The user can manually synchronize configuration data from the 

connected controls at any time.
