3.1.7 Input data (LcExponent, AS=5)
This chapter describes the input data when the
Actual Value Selector
(
AS
) is
set to
5
during transfer of
LcExponent(X)
. The 26 input data bytes (from the
4x50 unit) are structured exactly like during normal operation (
AS
=0), except
for the differences listed in the following:
LcRegister
is 100% identical to
LcRegister
during normal operation (
AS
=0),
except the
AS
will be set to
5
.
LcStatus(X)
is 100% identical to
LcStatus(X)
during normal operation
(
AS
=0), except the
LcStatus(X),
will always have a bit set (see
) stating that
LcSignal(X)
is
NOT
selected (i.e. normal oper-
ation NOT selected).
LcData(X)
will contain
LcExponent(X)
in the double word instead of
LcSignal(X)
which is transferred during normal operation (
AS
=0). The
LcExponent(X)
is a fixed value for the load cell used for internal scaling of
the raw load cell signal into SI units. This is done according to the following:
Exponent [Decimal]
