Diagnostic message Configurable Possible cause of error Corrective measure
Parameter assign‐
ment error
No One parameter, or the combi‐
nation of parameters, is not
plausible
Reassign the module pa‐
rameters
The wire jumper (terminals 10
and 11) does not match the pa‐
rameter assignment of the
measurement type.
Check wire jumper
Wire break Yes The connection of the trans‐
ducer is interrupted
Check the wiring
Resistance of sensor protec‐
tion circuit too high
Use a different type of sen‐
sor or modify the wiring, for
example, use cables with
larger cross-section
Channel not connected (open) Disable the channel group
("Measurement type" pa‐
rameter) or connect the
channel
Low limit violation of
measuring range / un‐
derrange
Yes
(Group diag‐
nostics)
Analog value below the under‐
range
Check the measuring range
selection
In the case of measuring range
4 mA to 20 mA, sensor may be
connected with reverse polari‐
ty.
Check terminals
High limit violation of
measuring range / un‐
derrange
Yes
(Group diag‐
nostics)
Analog value above the over‐
range
Assign a different measur‐
ing range

Article numbers
Standard module: 6ES7 650-8AR60-0AA0
Module with conformal coating: 6ES7 650-8AR60-1AA0
Properties
The analog input module AI 8 x TC/4 x RTD is characterized by the following properties:
● 8 inputs in 4 channel groups
● Measured value resolution, can be set for each channel group (depending on the set
interference frequency suppression)
– 9 bits + sign (integration time 2.5 ms) ≙ 400 Hz
– 12 bits + sign (integration time 16.67 / 20 ms) ≙ 60/50 Hz
– 15 bits + sign (integration time 100 ms) ≙ 10 Hz
