22 Mode Block --
The mode parameter is a structured parameter composed of
the actual mode, the normal mode, and the permitted mode.
Actual: Indicates the current operating condition.
Permit: Indicates the operating condition that the block is
allowed to take.
Normal: Indicates the operating condition that the block will
usually take.
17 Static Revision No -- 2
The revision level of the static data associated with the function
block. The revision value will be incremented each time a static
parameter value in the block is changed.

45 Pressure Value -- Variable
This parameter contains the Pressure value before scaling
calibrated range.
