  • Page 88: Parameter Data Record

    Parameter data record Parameter assignment and structure of parameter data record You have the option of reassigning module parameters with the user program while the CPU is in RUN. The parameters are transferred to the module using data record 128, e.g. with the WRREC instruction.

  • Page 97: Parameter Validation Error

    Parameter data record B.2 Parameter validation error 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.
