Current counter status = 12345 m

12 x 10 000 000 = 120 000 / 000 m

Calling up the error description
In accordance with NAMUR recommendation NE 107, a

Errors and warnings are saved in the register.
Errors directly affect the current output.
Warnings can be read via the HART-protocol and processed.
Errors and warnings that have occurred can be called up by using
the ‘Status register’ Menu. When the menu is opened, the
number of errors and warnings is displayed. When the error
(warning) register is called up, the type of warning or error is
indicated.
