Parameter validation error with data record 128

If you make the parameter setting in STEP 7 (TIA Portal), the parameter values are checked
before they are transferred to the technology module. This process prevents parameter
errors.
In other use cases, the technology module checks the transferred data record. If the
technology module finds invalid or inconsistent parameter values, it outputs an error code
(see below). The new data record is rejected in this case, and work continues with the current
parameter values until a valid data record has been transferred.
WRREC
When the CPU is in the operating state RUN, you can change the data record with the
instruction WRREC (Write Record). In case of errors, the WRREC instruction returns
corresponding error codes in the STATUS parameter.
Example:
Let us assume that an invalid value, e.g. 12, is written to the module for the input delay DI0
when WRREC is executed. As a consequence, the module rejects the entire data record. You
can recognize this by evaluating the STATUS output parameter of the WRREC instruction. The
STATUS output parameter is output as an ARRAY[1..4] of BYTE data with the value
16#DF80E101:
