Entry is only relevant if DRAK = 1
Enter the following here
• The limits of the range within which
values are interpreted as wire-
breaks ( DRAK)
• - 32768 if you have configured a
global limit value for wire-break in
DB1.
Becomes ”1” in the following cases
• if FB 250 accesses an analog input
which is currently being tested or
• if a discrepancy results in the case of
direct access with the parameter
DIR = 1 and the last valid value
instead of the current value is
assigned to output value XA.
The values XA, FB and BU are not up-
dated. Only the old values are available
for them.
1 Values of the scaled range (UGR to OGR)
2 If both bits F and BU = ”1”, passivation has taken place in the relevant modules. The passivation value is in the value
XA.
