Maximum Number of Modules
The modules include the interface module, power and electronic modules, and motor
starters.
The total width of an ET 200S is limited to 1 m. In addition, the maximum number of modules
in an ET 200S depends on the parameter length of the modules. A total of 244 bytes per
ET 200S are possible.

Example
The following example shows modules that have been used with a parameter length of a
total of 224 bytes in an ET 200S. There are also 20 bytes available for installation of
additional modules.
