What Is A Modbus Map?

Answer»

A Modbus MAP is simply a LIST for a slave device that defines

  • What the data is (eg. pressure or TEMPERATURE readings)
  • Where the data is stored (which tables and data addresses)
  • How the data is stored (data types, byte and word ordering)

Some devices are built with a fixed map that is defined by the MANUFACTURER. While other devices allow the operator to configure or program a CUSTOM map to fit their needs.
