In the case of the 2AI RTD High Feature, a wire break is reported for the measuring and constant-current lines of the
1
sensor.
The following applies for the modules 2AI TC ST and 2AI TC HF:

Reference channel error is not reported if the RTD module is not parameterized in the GSD file with the PT100 climate.
This applies to IM151-1 HIGH FEATURE (6ES7151-1BA00-0AB0 or higher), IM151-7 CPU and IM151-3 PROFINET IO
6ES7151-3AA00-0AB0 or higher).

Meaning
Module cannot use the
parameter for the
channel:
Inserted module does
not match the one
configured.
Faulty parameter
assignment.
Internal module error
(diagnostics message
at channel 0 applies to
the entire module)
Value is above the
overrange.
Value is below the
underrange. Short-

Remedy
Correct the configuration
(align actual and preset
configuration).
Correct the parameter
assignment (diagnostics
wire break only for the
allowed measuring
range parameterized).
Replace the module.
Correct the
module/actuator tuning.
Correct the
module/actuator tuning.
Correct the process
wiring.
Check the reference
module (2AI RTD
Standard).
