Profibus NIU. The current requirement of U
NIU, so additional power terminals must be used. The number of additional power
terminals to be used depends on the arrangement of the modules.
As discussed in chapter 4, the recommended sequence of the modules in this
example is:
If this arrangement must be maintained, two additional power terminals are

U /U :
S M
If a system design goal is to use as few terminals as possible, the module
sequence must be changed. In this case, only one additional power terminal would
be needed:
U
Please note that while the I/O modules must be rearranged in order to minimize
the number of power terminals required, the recommended module sequence is
preserved downstream of each power terminal.
