No. Symptom Cause Remedy
1 ERR/ALM indicator is lit. A non-fatal error has occurred. Refer to 6-1-10 .
No. Symptom Cause Remedy
1 Conversion data does not
change. 1. The input is not set for being
used.
Check PLC setup,set analog input to
“Use” and restart CP1E CPU Unit.
2. The input wiring is wrong. Correct wiring according to 3-1-3 .
3. The input device is not working. Using a tester, check to see if the
input voltage or current is changing.
4. there is a disconnection. Check A434.00 (AD0) or A434.01
(AD1) flug (open-circuit disconnec-
tion.)
2 Value does not change as
intended. 1. The input signal range setting is
wrong.
Correct the input signal range setting
and restart CP1E CPU Unit.
2. The input device’s signal range
does not match the input signal
range for the relevant input num-
ber at the CP1E CPU Unit.
Check the specifications of the input
device, match the settings for the
input signal ranges and restart CP1E
CPU Unit.
3. When using the 4 mA to 20 mA
range, the VIN and I IN terminal is
not shorten.
Short VIN and I IN terminal.
3 Conversion values are
Inconsistent The input signals are being affected
by external noise. Insert a 0.01-
µ
F to 0.1-
µ
F ceramic
capacitor or film capacitor between
the input’s VIN/I IN and COM termi-
nals.
Use averaging function.
No. Symptom Cause Remedy
1 Analog output does not
change. 1. The output is not set for being
used.
Check PLC setup,set analog output
to “Use” and restart CP1E CPU Unit.
2. The conversion value is set out-
side of the permissible range.
Set the data within the range.
-10 to 10V: F448 to 0BB8 Hex
Other ranges: 0000 to 1770 Hex
2 Output does not change as
intended. 1. The output signal range setting is
wrong.
Correct the output signal range set-
ting and restart CP1E CPU unit.
2. The Analog I/O specifications of
the output device do not match
those of the CP1E CPU Unit
(e.g., input signal range, input
impedance).
Change the output device.
3 Outputs are inconsistent. The output signals are being affected
by external noise. Try changing the shielded cable con-
nection (e.g., the grounding at the
output device).
