B.7.4 M-Bus I/O Signals
Each M-Bus device represents a specific type of hardware meter. The
device editor is used to create new device types, or to modify existing
types, as shown in the following screenshot.
Each signal can be used to read or write the value of one or more
metered values within any meter devices of the type being defined.
• Field Type and Sub-Type – Allow the required metered value
type to be selected for the applicable meter. The selected field type
automatically sets the applicable raw value type, and the field type
name indicates the engineering units of the value returned by the
meter.
Note
• Normally Sub-Type is left blank, but it may be used to select
between two slightly different variations of a single field type
(for example,. +ve and -ve for heating/cooling respectively).
