Analog Value Processing
S5-115F Manual
Call and parameter assignment:
1
Values of the scaled range (UGR to OGR)
2
If bits F and BU are both=”1”, passivation of the relevant module has taken place. The passivation value is in the
value XA.

Set DRAK = ”1”
•
if you want to implement wire
break monitoring according to
method in 6.5 and
•
if the current analog value lies
outside the wire break limits.
ODGR
1
Wire break upper
limit
Only relevant if DRAK = 1
Enter the following here:
•
The limits of the range within
which values are interpreted as
wire breaks
•
- 32768 if you have configured a
global limit value for wire break in
DB1.

Passivation value
PASS
KF
D
When passivating of the module, the
safety-related passivation value is
written into the result word instead of
the AI value read in.
EINZ
Selective sampling
E
BI
A ”1” initiates selective sampling
(only in the case of the AI 460)
DIR
Direct access
E
BI
Set DIR=”1” if direct access is desired
XA
Output value
A
W
The scaled analog value is ”0” in the
event of a wire break
FB
2
Error bit
A
BI
Becomes ”1” in the event of a wire
break
BU
2
Overrange
A
BI
Becomes ”1” if the accessed module is
currently executing selective sampling
TBIT
Activity bit of the
accessed module
A
BI
Becomes ”1” if the analog input of one
or both subunits exceeds the nominal
range
TKON
Time conflict
A
BI
Becomes ”1”
•
if FB 250 accesses an analog input
which is currently being tested or
•
if a discrepancy has resulted in the
case of direct access with
parameter DIR =1 and the output
value XA is assigned the last valid
value instead of the current value
XA, FB and BU are not updated. Only
the old values are available.
