Methods
The FOUNDATION Fieldbus specification provides for the use of so-called methods to simplify the
operation of the device. A method is an interactive sequence of steps that must be followed in order
to obtain a particular function from the device.
The Micropilot M has got the following methods:
• Set to customer default
• Diagnostics
Most of these methods are identical to the respective function group in the operating menu. A
detailed description of them can be found in the "Description of Instrument functions", BA221F/
