Flame temperature high byte
Flame temperature low byte
Intensity for sensor 1, if safe as second Flame-relay
Flicker-Frequency for sensor 1, if safe as second Flame-relay
AC-Amplitude for sensor 1, if safe as second Flame-relay
Quality for sensor 1, if safe as second Flame-relay
Collected data can be sent to FEX (0 = no, 1 = yes, and 2 = stop)

Sensor type (IR, UV, and DUAL)
Holding Registers (Programmable Parameter Registers)
The holding registers provide the ability to read/set the scanner parameter values to/from
a MODBUS master.
Change these values only using the Flame Explorer tool. There is an automatic
procedure that performs safety operations in the Flame Explorer tool. This cannot
be replicated (and MUST not be replicated) on a generic MODBUS master.
