Scanner Process Values
5111 LoFlame temperature high byte
5111 HiFlame temperature low byte
5112 LoIntensity for sensor 1, if safe as second Flame-relay
5112 HiFlicker-Frequency for sensor 1, if safe as second Flame-relay
5113 LoAC-Amplitude for sensor 1, if safe as second Flame-relay
5113 HiQuality for sensor 1, if safe as second Flame-relay
5114 LoCollected data can be sent to FEX (0 = no, 1 = yes, and 2 = stop)
5114 HiSpare
5115 LoDTC version flag (0x0a = Rev 04L and 0x0e = Rev 004)
5115 HiSpare
5118 LoSpare (also spares 5116 and 5117)
5118 HiSensor 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.
