Operation Reads the internal (non-scaled) value of the source of a pointer parameter. The pointer
parameter is specified using the Group and Index inputs.
The value of the source selected by the pointer parameter is provided by the Output pin.
Error codes are indicated by the error output (Error) as follows:
Inputs Parameter group (Group): DINT
Parameter index (Index): DINT
Outputs Output (Output): Boolean, INT, DINT, REAL, REAL24
Error output (Error): DINT

Operation The input value (IN) is written to the defined parameter (Group and Index).
The new parameter value is stored to the flash memory if the store input (Store) is 1.
Note: Cyclic parameter value storing can damage the memory unit. Parameter values
should be stored only when necessary.
Error codes are indicated by the error output (Error) as follows:
Inputs Input (IN): DINT
Parameter group input (Group): DINT
Parameter index input (Index): DINT
Store input (Store): Boolean
Outputs Error output (Error): DINT
