  • Page 35: Configuration And Set Up

    POWER ELECTRONICS PROFIPOWER 4.3. Configuration and Set up. 4.3.1. Profipower Type 1 module. It is a generic module that allows 5 output registers and 5 input registers. To configure this generic module, we will define the parameter “Scenario”. The Scenarios are the Modbus frames that we want to send.
  • Page 36 PROFIPOWER POWER ELECTRONICS The defined frames for this module are: 10 bytes of Data-Output and 10 bytes of Data-Input. Therefore, the maximum number of selected Modbus registers will be 5 for the writing Scenarios and 5 for the reading Scenarios. That is, all the registers selected for the configured writing Scenarios do not exceed 5.
