15.2.1 MODBUS Registers

Coil Status Registers
The coil status registers provide access to the SF910i relay values. These values are
read using MODBUS function code 1.
This information can be read by any MODBUS master conveniently configured.
Table 15.2: Coil Status Registers (MODBUS)
Flame status (0 = no flame and 1 = flame)
Flame status for second sensor (if dual)
FSA is used for Flame Calculation Algorithm on Flame-relay
FSB is used for Flame Calculation Algorithm on Flame-relay
FSC is used for Flame Calculation Algorithm (single sensor, dual sensor, or Safe-relay
as second Flame-relay)
FSD is used for Flame Calculation Algorithm (single sensor, dual sensor, or Safe-relay
as second Flame-relay)
Combined Unit Fault Status (0 = no fault and 1 = fault)
Scanner Fault (0 = no Scanner-Fault and 1 = Scanner-Fault)
Sensor 1 Fault (0 = no fault and 1 = fault)
Sensor 2 Fault (0 = no fault and 1 = fault) If dual sensor only
The scanner is using the factory default configuration (0= no, normal condition and 1 =
yes, the module must be configured)
The flame relay is currently overridden (1 = no and 1 = yes)
The scanner is executing an Auto Tune procedure (0 = no and 1 = yes)
Flame status for second Function Set (if single and Safe-relay as second Flame-relay (0
= no flame and 1 = flame)
The safe relay is closed (meaningful is safe relay used as quality or temperature relay)
