Dummy unit for the I/O system
or
Dummy unit for the CPU system
can somebody maybe explain what is dummy unit for?
more about the context on

A dummy unit is the average poster on SED. Dummy units take up space, waste
bandwidth, and are for creating discord.

No. A "dummy unit" is a student who can't at least craft a question
so it makes sense. (And ask it in such a way that it's not obvious
that it's a homework problem :)

well actually im not a student, i'm trying to figure out how it can be
called in Polish, so i have to understand what is it

thanks for help

This is a modular system. You buy the basic case and you can fill
it as required with the units you need.

The case provides space for 2 CPU units. If you only need a
single CPU, you just buy 1 CPU unit and 1 dummy CPU.
This fills the area that would otherwise leave a hole and can
easily been swapped for an extra CPU when required in the future.
The ratio is, that a dummy is much cheaper as a real unit.

thanks !!!
i have one more question "terminal base unit" it also can be found in pdf
file,
does this mean "base unit of terminals", "unit of base terminals", " or
"unit of bases of terminals"?
(well i think its 3 option, but im not sure)

They mean the physical place where you actually make the
connections to the unit.

First you select an IO unit to match the things you actually want
to measure (electrical part) and then you choose the I/O terminal
base unit to fit the wires to (mechanical part).

(At least, that's what I read into it :)

so base is just kind of cocket or connector?

No, not really.

Maybe an example will clarify:
Say, you have to mount 20 sockets onto a concrete wall.
You could drill 40 holes into the wall, 2 for each socket.
Or you could drill just 4 holes into the wall, use them to fix a
piece of wood to the wall and just screw the sockets onto the
wooden panel. In this case, the wooden panel is used as a base.

When you select this controller, you first decide which kind of
wire termination you want. Eg. if you want fuses for all
incoming wires, you select 200-TBNF.
This unit is then mounted to the rail, hence it's name 'base'.
All wiring is connected to this base unit and this base unit
connects to the IO modules and the system bus.

In industrial controllers, the wiring is usually the last thing
you want to replace. Therefore, it is attached closest to the
wall and to a unit that is as thumb as you can get.
This will allow you to change the intelligent IO unit without
rewiring.
