1.8 Data Sets and Data Types
The M6xx meters are shipped with a pre-defined set of data points and data types. These fixed points do
not change. The List of Available Measurements may be found in the M65x or M66x User Manual. The
Ethernet port and web browser are required to create the configurable points list. See section 1.11 for
more detail.
For users who wish to use M6xx meters on systems configured for other Bitronics products, a Legacy
point list may be selected. This Legacy list cannot be modified, and will cause the M6xx to emulate the
response of a Bitronics MultiComm or PowerPlex unit.
1.8.1 Configuring the Class-0 Response
The Class-0 request is a very short request to “give all essential data”. Since the M6xx is capable of
providing a significant amount of data, provisions have been made to tailor the response to this request.
A web browser interfacing to the Ethernet service port is required to change the Class-0 response. The
Legacy Class-0 response can also be configured.
When selecting a Legacy points list, the user will be prompted to enter a BiLF Class0 mask. The following
table shows what bits must be set to get the legacy class0 response.
In Legacy mode, a zero BiLF Class0 mask returns a fairly small collection of points. As each bit is set,
more points are added to the response.
