6.5 Fault types, causes, and corrective measures
The "Fault types, causes, and corrective measures" table below lists the messages of the
F-DI 4/F-DQ 2 Fail-Safe module. These messages are displayed in the TIA Portal under "Online
& diagnostics" > "Diagnostics" > "Diagnostic buffer". When you highlight an individual text line
in the diagnostic buffer, the Event ID for that text item is displayed, along with module
identity and location that generated the message. You may need to expand the window to
see all information.

16x0001 Short-circuit F-DI 4/F-DQ 2
digital outputs
A channel problem has
been detected where
either the P terminal or
M terminal is at an
unexpected potential
• Short-circuit of the
output
• Short-circuit be-
tween channels
with different sig-
nals
• Output overload
• "Maximum read-
back time switch
on test" value is
configured too
small
• Short-circuit of
output to M
• Defective output
driver
• Eliminate the short-
circuit
• Eliminate the over-
load
• Increase "Maximum
readback time
switch on test" if
permissible
• Replace the fail-
safe module
16x0005 Overtemperature Module
• Overtemperature
at microcontoller
• Overtemperature
at I/O
Shutdown due to vio-
lation of high tempera-
ture limit value in the
module case
Check the ambient
temperature. Once the
fault has been elimi-
nated, switch the
power off and on
16x0006 Wire break Module Wire break failure.
The module can detect
a wire break when all
of the following are
true:
•
The channel is
wired using a PM
load
• The PV=0
• The wire break
diagnostic is ena-
bled
Output is activated:
•
No load is connect-
ed to the PM out-
put
• Output is wired in
output application
mode 2
• Too small of a load
is detected
• Change the output
load characteristics
• Deactivate unused
channels
• Disable wire break
diagnostic for the
offending channels
