2.3 Maximum Number of Connectable Modules/Maximum Configuration
Maximum Number of Modules
The modules include the interface module, the power and electronic modules, and the motor
starters.
The overall width of an ET 200S is limited to 2 m.
The following restriction applies for IMs as of 6ES7151-1BA01-0AB only when operated in
DPV0 mode:
● The maximum number of modules in an ET 200S also depends on the parameter length
of the modules. Each ET 200S supports a total of 244 bytes.
For further additional information refer to the
ET 200S Distributed I/O System Operating
Instructions.
