The Segment Expander Module should be used when more than 8 input and output modules are required. Since the total number of modules that the MCPU-1 can communicate locally is 32, we can only use a maximum of 3 segment expander modules. The calculation is done as follows: 32 Modules / 8 Modules per segment will give a maximum of 4 segments. Since the first segment doesn’t use an expander module, we can only use an expander module from the second segment on, giving a total of 3 MEXP-1 at most.
