Combing modules for the configuration

Introduction
The IM151 has a maximum address area of 256 bytes for inputs and 256 bytes for outputs.
For a better utilization of the available address space of the IO controller, you can group
multiple electronic modules/ load branches within a byte in the input or output area of the
process image. This is achieved by the systematic arrangement and designation of the
ET 200S electronic modules/motor starters.
Note
Grouping is only possible with the IM151-3 PN after 6ES7151-3AA10-0AB0 and
V5.3 SP 3.
A list of the address space requirements for the individual modules is to be found in the
appendix.
You can combine the following device types within one byte:
● Digital input modules
● Digital output modules
● Motor starters (direct starters and reversing starters)
Other modules may be connected between the modules that can be combined.
The procedure is identical to that for PROFIBUS DP.
Modules are grouped during configuration. By selecting a module label without "*", you open
a byte. By selecting a module with "*", you fill the byte until all bits are occupied.
The generation of interrupts results in the following behavior:
Interrupts at removed DO modules
