B.2 Parameter Validation Error - Siemens SIMATIC S7-1500 Manual

B.2 Parameter validation error
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 parameter data record. If
the technology module finds invalid or inconsistent parameter values, it outputs an error
code (see below). The new parameter data record is rejected in this case, and work
continues with the current parameter values until a valid parameter data record has been
transferred.
WRREC
When the CPU is in RUN, you can change the parameter 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 when WRREC is executed, an invalid value, for example 9, is written to
the module for the signal type. As a consequence, the module rejects the entire parameter
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#DF80E111:
