2.2.2.6 Command Tables
The command tables enable the Modbus master/client to issue control commands
to the fire units.
A read/write holding register is foreseen for each of the objects listed below. Given
an initial object state, a data value corresponding to a control action can be written
in the register to trigger the command that is then expected to modify the object
state and therefore cause a corresponding change in the object input registers.
Note that the holding registers store the code of the latest command after its
execution.
The list of command tables includes:
Global panel acknowledgement and reset
CMDT_FC20 (Holding register, default base address 25000)
