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 from the data of the modules as mounted from left to right in the automation system CPX-E.
Accordingly, the Modbus addresses also depend on the combination of the modules of the automation
system CPX-E. The Modbus addresses are arranged in ascending order without gaps i.e. n, n +1, n
+2 ... , where n corresponds to the first Modbus address of the module.
