Displayed data:
The device only displays the most important data for reasons of easy interpretation and
not to confuse the reading personell. Some meters offer actual and historical values,
different tariffs and additional devices like pulse counters in a heat meter. The first row
always shows the primary address and ID for a clear association of the data to the
respective meter. The first two characters in this row give information about the tariff.
The second row displays the due-date or the data with physical unit. The first two
characters show information which distinguishes between the different values:
The character "A" marks current values which are characterized by storage no. 0. The
slave contains activated temporary or permanent error bist in the Status byte , an "E"
will be shown. The first character follows one digit for the device (0 = main device).
Filtering data:
To make the readout of data easy the device only displays the most important values of
the meters. Only the first respond telegram after initialization with SND_NKE is
supported. The data is limited to tariff 0 to 3, device 0 to 7, storage no. 0 and 1 and
function "instantaneous". The marking of these values is described above.
The energy, volumes, temperatures (flow, return, differential), volume flow and power
are displayed if the are included with the respond frame. The limitation is derived from
accepting only the VIF´s $00 ..$1F, $58..$63 and $6E. These are the following basic
units and additional power of tens: Wh, J, l, kg, W, l/h °C and HCA. Also available points
of time are supported. A maximum number of 30 entries can be viewed from one meter.
