the control is on will become highlighted. In this exam-
ple, Boiler 1 has been selected. The options available for
Boiler 1 (touch buttons at the bottom of the screen)
include: Rename Boiler; Remove this Control (the
S7999D would no longer be able to access this address);
Access the Expanded Annunciator (if connected);
Access UDC control(s) (if connected); Modbus Configu-
ration (ability to read and write (if writable) specific Mod-
bus register addresses).

b. The "Remove Control" button allows the used to
remove this specific Modbus address. A dialog box
will first appear asking for conformation to remove
this control address. Note that if the control address
is accidentally removed, touching the "Refresh" but-
ton will cause the R7999D to search the network and
discover any "new" controllers on the network.
c. The "Expanded Annunciator" button allows the user
to rename the T4 – T22 terminals of the Expanded
Annunciator. See "Renaming the Expanded Annun-
ciator Terminals" on page 52 for details.
d. The "UDC Controller" button allows the user to dis-
cover UDC controllers on the network and to assign
one or more of the discovered UDC controllers to
burner/boiler systems. See "UDC Controllers" on
page 44 for details.

e. The "Modbus Configuration" button provides an
advanced troubleshooting function that allows the
user to read and write to individual Modbus registers.
The user can read and write any Modbus register in
the S7810M Modbus Module or UDC controller.
The user can enter the Modbus address as either a
decimal or hexdecimal value. When writing a regis-
ter value the user can also enter the value in either
decimal or hexadecimal units.
When the user requests a Modbus register read, the
S7999D reads that register and up to 20 of the next
consecutive registers immediately located after the
first register. The contents of all the registers are dis-
played together. This automatic block read eliminates
the need to repeatedly read consecutive Modbus
registers.
The user can toggle back and forth between decimal
and hexadecimal views.
S7999D Home Page
When the S7999D is connected to a single boiler system (a
single S7810M Modbus Module), the home page will show an
icon for each of the controllers connected to the S7810M
Modbus Module. If a Fuel Air Ratio Control is connected to one
of the Com ports, that is configured for Fuel/Air Ratio only
(Commission), icons will also be displayed for the Fuel Air
Ratio Control system.
A fault in one of the controllers, will cause a Fault Dialog box to
pop-up on the Home Page. The Fault Dialog box will indicate
which component has a fault and a fault message. If the
"Sound audio alarm for faults?" box has been checked,
(Display Setup page, General Tab), an Alarm Bell button will
appear in the lower left hand corner and the S7999D's audio
alarm will be sounding. The Alarm Bell button can be touched
to silence the S7999D audio alarm.
The icon for the controller with the fault will change to a red
color. See Fig. 22 on page 15.
Below each UDC controller icon one key status variable can be
selected for display.
