  • Default Modbus/TCP address map (Appendix A). The addresses can be changed in the web console under user-defined Modbus addressing; this map fits the defaults.
  • 32-bit values are high word first.
  • The manual lists 12 DI and 8 DO addresses: the DIO channels appear in both, as inputs or outputs depending on their mode.
