Input
Parameters
‘identifier’: 'M*.DataIn1', 'M*.DataIn2', or 'M*.DataIn'
Description
This query returns the accumulated bit counts and coding specific counts
since start of accumulation period. The results are combined to an
expression. An expression is comparable to a struct in a programming
language. It’s a set of parameter of different types separated be a comma
and enclosed by parenthesis.
The returned expression contains a timestamp, the location and a set of bit
counter values.
(TimeStamp, “Location”, Counted1s, Counted0s, Erroneous1s,
Erroneous0s[, coding specific counters])
