What is the definition and access type for 'Input Registers' in the Modbus data structure?
Answer
16-bit input values, Read Only
Input Registers are designated in the Modbus data model as holding 16-bit input values. Critically, these registers are strictly read-only; a master device can query them to retrieve data but cannot alter their contents. These are typically used in industrial settings to communicate real-time measurements obtained from sensors, such as retrieving a current temperature or pressure reading, which are reported by the slave device.
