After selecting all of the components for your AIS system, it is then necessary
to
configure the system and assign input/output numbers for each of the modules you
have chosen.
First of all each of the modules in your system must be allocated
to
an
110
slot on
either the CPU or extension base unit. So write in the model numbers of the
modules you have selected against the slot number where you want to locate them
on the base units selected. A good idea when doing this is to keep all the input
modules, output modules and special function modules together in groups, this
makes
it
much easier when it comes
to
programming and installation later on.
When you have allocated an
I10
slot
for each of the modules, it is then necessary
to
assign numbers
to
all of the inputs and outputs in your system. The numbers
range from
0
to FF, and are counted in hexadecimal i.e.
0,
1,
2, 3, 4,
5,
6,
7,
8,
9,
A,
B,
C,
D,
E,
F with the starting point for counting the module in slot
0
of the CPU
base unit. From the module in slot
0
the numbers follow on consecutively through
all the modules on the CPU base unit and then on to the modules in the extension
base unit, if one is used. Please note when assigning the
I10
numbers that single
I/O
slot special function modules occupy 32 points, two
110
slot special function
modules occupy
48
points, and spare or vacant
110
slots
occupy 16 points.
