Adaptive program fault and aux code formats
The format of the aux code:
If the state number is zero but the block number has a value, the fault is related
to a function block in the base program. If both state number and block number
are zero, the fault is a generic fault that is not related to a specific block.

Sequence program
An adaptive program can contain base program and sequence program parts.
Base program is run continuously when adaptive program is in running mode.
The functionality of the base program is programmed using function blocks and
system inputs and outputs.
Sequence program is a state machine. This means that only one state of the
sequence program is run at a time. You can create a sequence program by
adding states and programming the state programs using the same program
elements as in the base program. You can program state transitions by adding
state transition outputs to the state programs. The state transition rules are
programmed using function blocks.
The number of the active state of the sequence program is shown by parameter
07.31 AP sequence state
