D.1

Overview of Modbus® TCP objects

This chapter describes the representation of the CPX terminal within the Modbus®/TCP object model.

Some information is in English, even in the documentation in other languages, so that the original terms of the protocol specification can be used clearly.

D.2

Commands and addresses

The table below shows the connection between the Modbus® address and data or parameters of the CPX terminal. The data are assigned to various groups.

D.4

Process data (Group B and D)

The process image of the input data (Group B) and of the output data (Group D) is composed without gaps of the data of the modules as mounted from left to right in the CPX terminal.

The Modbus® addresses depend accordingly on the modules mounted on the CPX terminal. They are arranged in ascending order without gaps (n, n +1, n +2, ... ; n corresponds to the first

Modbus® address of the module).
