  • Page 23: Configuration

    9.3 Configuration This section demonstrates the configuration process for RP20 series I/O modules using the RP20 series EtherCAT coupler as an example. The RP20 series offers 2 configuration methods: Method 1: Configuration via scanning. This method requires an actual slave device to be connected.

  • Page 24: Usage Demonstration

    Fig. 9.3-3 Add modules 9.4 Usage Demonstration The digital modules of the RP20 series are defined as byte transfer in the device description. After configuration, each module is automatically assigned a unique address, which can be viewed and utilized in the "Module I/O Mapping" interface in the configuration panel.
  • Page 25 RP20 Series EtherCAT bus-based coupler user manual Fig. 9.4-2 Use the address directly Method 2: Address Mapping (Byte /Bit) In this method, the I/O channel addresses are directly mapped to specific variables through the "Module I/O Mapping" interface. This allows the variables to be directly associated with the corresponding I/O channels for use in the program.
