In Simatic S7 the meas-
ured value is always
presented as 0
Only four bytes are con-
sistently loaded in the PLC
Use function component SFC 14 to load 5 bytes con-
sistently
Measured value on the
display and adjustment
module does not corre-
spond to the value in the
PLC
The menu item "
Display -
Display value
" is not set to
"
PA-Out
"
Check values and correct, if necessary
No connection between
PLC and PA network
Incorrect adjustment of
the bus parameter and the
segment coupler-depend-
ent baud rate
Check data and correct, if necessary
Instrument does not ap-
pear during connection
setup
Profibus DP cable pole-
reversed
Check cable and correct, if necessary
Incorrect termination
Check termination at the beginning and end points of
the bus and terminate, if necessary, according to the
specification
Instrument not connected
to the segment, double as-
signment of an address
Check and correct, if necessary
In Ex applications, the regulations for the wiring of intrinsically safe
circuits must be observed.

E013
no measured value avail-
able
•
Probe insulation damaged, short-circuit due to per-
meating, conductive medium
•
Exchange the instrument or send it in for repair
Shortcircuit in the probe,
e.g. because of moisture in
the housing
•
Remove the electronics module out of the probe and
check the resistor between the two marked plug con-
nections according to the figure in paragraph "
Check
the resistance in the probe
".
•
There should be no contact between any of the con-
nections (high resistance)
•
If there is still a connection, exchange the instrument
or return it for repair
E017
Adjustment span too small Carry out a fresh adjustment and increase the distance
between min. and max. adjustment
E036
no operable sensor soft-
ware
Carry out a software update or send instrument for re-
pair
E113
Communication conflict
Exchange the instrument or send it in for repair
Depending on the reason for the fault and the measures taken, the
steps described in chapter "
Set up
" may have to be carried out again.
9.3 Exchanging the electronics module
If the electronics module is defective, it can be replaced by the user.
