Parameter Validation Error - Siemens SIMATIC ET 200SP Manual

A.2

Parameter validation error

If you make the parameter settings in STEP 7 (TIA Portal) or in STEP 7, 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
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 DF80E113
