Description
This block fetches a summary of the meter type and product group, which may
be used by the PLC to tailor its logic for providing process input values to the
AFC. Since there is no significant output, the "ignore output" bit (bit 8) has no
function. For firmware version 2.05 and later, non-zero stream information is
returned; for firmware version 2.04, the one stream is always enabled and active
which renders stream information redundant, and returned stream information is
all zero. The summary is returned as a single element of data, a bitmap having
this layout:
Bit Description
0 meter is in alarm
1 meter is enabled
2 [spare]
3 [spare]
4 metering device is linear (pulse)
5 product phase is liquid
6 primary input is flow rate / frequency
7 [spare]
8 stream 1 enabled
9: stream 2 enabled
10 stream 3 enabled
11 stream 4 enabled
12 to 13: number of active stream (0-based: 0 thru 3)
