3.1.8 Input data (TestValue, AS=6)
This chapter describes the input data when the
Actual Value Selector
(
AS
) is
set to
6
during transfer of
TestValue(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
6
.
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
TestValue(X)
in the double word instead of
LcSignal(X)
which is transferred during normal operation (
AS
=0). The
TestValue(X)
are fixed hardcoded values, which can be used for testing data
handling on the EtherNetIP master. The values transferred are the following:
TestValue(X) Value [Decimal]
Value [Hexadecimal]
TestValue(0)
123456
0x0001E240
TestValue(1)
-123456
0xFFFE1DC0
TestValue(2)
12345
0x00003039
TestValue(3)
-12345
0xFFFFCFC7
