Analog input module AI 4xU/I/RTD 4xM12 (6ES7144-5KD00-0BA0)
Manual, 08/2018, A5E32350124-AD
Diagnostics alarms - for the measuring range: 0 V to 10 V and 4-DMU 0 mA to 20 mA
Error code Meaning
1 Short-circuit encoder supply to
H
ground
7 Value is above overrange.
H
Value is below underrange.
H
9 Value is significantly above or
H
below underrange/overrange.
10 Module parameter assignment is
H
faulty
16 At least one hardware interrupt
H
could not be signaled because
too many hardware interrupts are
pending.
Diagnostics alarms - for the measuring range: 150 Ω and 300 Ω
Error code Meaning
6 Impedance of encoder circuit too
H
high
Wire break between the module
and sensor
Channel not connected (open)
7 Value is above overrange.
H
10 Module parameter assignment is
H
faulty
16 At least one hardware interrupt
H
could not be signaled because
too many hardware interrupts are
pending.

Remedy
Correct interplay between module
and encoder
Correct interplay between module
and sensor
Correct interplay between module
and sensor
Correct interplay between module
and sensor
Correct the parameter assign-
ment
Correct the program or the pro-
cess
Remedy
Use a different encoder type or
modify the wiring, for example,
using cables with larger cross-
section
Connect the cable
Deactivate diagnostics
•
Connect the channel
•
Deactivate channel
•
Correct interplay between mod-
ule and sensor
Correct the parameter assign-
ment
Correct the program or the pro-
cess
