3.3 Limitation of connectable modules/maximum configuration
Maximum configuration per potential group
The number of modules that can be connected depends on the total current of all modules in
a potential group. This total current must not exceed the maximum current-carrying capacity
of the power modules or COMPACT modules you are using.
The total current is governed in large part by the digital output modules.

IM151-1 COMPACT
DP master 32-byte diagnostic message frame length
You can use the ET 200S with DP masters with a diagnostic frame length of 32 bytes
because you can set the length of the diagnostic frame in all the interface modules.
