Unity Application Generator
How Can I…
Gather alarms from different Control Modules
Issue
●I want to generate a horn alarm in such a way that if there
is a alarm in any of the Control module, then the horn
alarm output should be active.

How to do..
Basic explanation
●This can be done by defining a data type of type arrays.
●Then creating a variable of this array type.
● Goal:
● Define a data type in Unity
● Import this data type in SCoD Editor.
● Create a variable in UAG of this type
● Use the array in CM

How to do..
In Unity
●Under UAG
customization PLC
User defined
Module, a new module
can be inserted.
●By clicking on User
defined block, a list of
existing blocks will be
appeared.
●New device can be
added by using ADD
option.

In Unity
●By clicking on ADD
option, this screen will
appear.

How to do..
In Unity
●User can select
Module category.
These options are
available
●User can select
possible rack type.
These options are
available

How to do..
In Unity
●We have named the
device as MyGeneric
with Complex IO as
Module category and
Rack is of type
Ethernet IO.
●Description and Icon
can be changed.
●IO Areas can be
defined each area for
Input, Output or both
can be defined.

7
How to do..
In SCoD Editor
●By clicking on IO
Mapping, IO can be
mapped for each areas.
Here we are defining
words under IO Area
“Command”
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
8
How to do..
In SCoD Editor
●For each IO area,
number of bytes, data
types, description and
quantity can be
defined.
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
9
How to do..
In Customization
●In this example, we have defined two IO areas under
“Commands” and they look like this:
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
10
How to do..
In UAG
●Similarly, we have defined two IO maps for “Status”
IO area.

11
How to do..
In UAG
●After analyzing and
saving the customization
file, the project should be
opened in UAG.
Following message will
appear:
●Note: We have selected
ETHERNET IO , it
should be ensured that a
PLC with proper
Ethernet ineterface is
available.
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
12
How to do..
In UAG
●Under the PLC, a
new rack should be
included.
●Following
parameter should
be selected.

13
How to do..
In UAG
●Under the new
Ether IO drop, rack
should be opened
with “Open Rack”
option.
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
14
How to do..
In UAG
●Under the rack, the
new module can be
inserted.
●Following
parameters should
be selected.
●Note: the new
module
“MyGeneric” should
be available under
MODULE column.

15
How to do..
In UAG
● By clicking on
“Open IO”, this
screen should
be appearing
● TO test,
following
variables
should be
created, under
variable table
in UAG.
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
16
How to do..
In UAG
●The
variable
should be
connected
to input
/output of
the newly
developed
device..
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
17
How to do..
In UAG
●The new block will
appear like this
under UAG
Topological viewer
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
18
How to do..
In Unity
●UAG will
generate
Unity project
with read
/write area
under IO
Scanner
Read /write areas
for IO scanner
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
19
How to do..
In Unity
●UAG will generate
sections for
communication and
the section will be
containing the
variables like this
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
20
How to do..
Very important: Note
●Please note that we
have written in our
new device, the slave
index as “0”.
●That is why it was
appeared in Unity like
this:
Schneider Electric - EU – Hussain Ahmed – 11.11.2008
21
How to do..
Very important: Note
● But this indexing has to
be configured according
to the requirement of
the device. We have
placed 22, results are
like this:

Recommendations /Notes
● In IO Scanner, in one telegram, one can write/read maximum 100
words
● We strongly recommend to do the address ranges in consecutive
address areas. So if the first area is starting from 1002, then it is
better to place the next address area at 1004 and not at 1120.
● It is very important to understand the address ranges of the
device.
● We have used two different IO mapping areas for “inputs” and
“Outputs”. That is why the UAG has generated two IO scanning
entries. By using type “Input /Output” there will be only one IO
scanning entry.

Conclusion
● In UAG new devices can be included by defining them
under Customization.
● There are different method of communications and rack
types possible
Thanks for your attention!
