Map local will indicate "number", "address", or "Modicon register", depending on your preference which you set under User Settings.

Register Number or Address – Enter the number (starting at 1) or raw address (starting at 0) as applicable. Do NOT enter 40001 for holding register 1 if you have not selected Modicon as the display format in your User Settings.

Modicon Register – Enter numbers like 40001 for the first holding register if you have selected Modicon representation in your User Settings.

As remote – The remote Modbus register address or number that this local address should be viewed as by remote clients or masters. Follow the same rules for number, address, or Modicon register as for the local value.
