Assembling the M7-400
This Chapter
The assembling of an M7-400 automation computer is largely identical to that of an
S7-400 programmable controller. Most of the instructions in the S7-400 chapters
can therefore be applied to the M7-400. Wherever details relate specifically to the
M7-400, these are pointed out to you at the beginning of each S7-400 chapter with
a cross-reference to the corresponding M7-400 section.
The headings of the second-digit sections of this chapter are largely the same as
those of the corresponding S7-400 chapter to guide you through the text.
