Modifying the program with the PLC in RUN mode
With Unity
™
Pro, changes can be made to the program when the PLC connected to
the programming terminal is in RUN mode. These modications are performed with
the following operations:
The application contained in the PLC is transferred to the PC terminal running b
Unity Pro, if necessary.
Program changes are prepared. These program modications can be of any type b
and in any language (IL, ST, LD, FBD and SFC), for example, addition or deletion
of SFC steps or actions. The code of a DFB user function block can also be
modied (however, modication of its interface is not permitted).
These program changes are updated in the PLC (in RUN mode). b
This function makes it possible to add or modify program code and data in different
parts of the application in one single modication session (thus resulting in a unied,
consistent modication with respect to the controlled process). This increased
exibility affects the amount of program memory required.
Cross-references function
Unity Pro's cross-references function is available in standalone mode (ofine) and
when connected to the PLC in Run (online). This allows users to view the elements of
a PLC application when searching for any type of variable. This view indicates where
the declared variable is used, as well as how it is used (for writing, reading, etc). This
function also provides access to the Search/Replace function for variable names.
The variable search can be initialized from any editor (language, data, runtime
screen, animation table, etc).
Import/export function
The import/export function available in Unity Pro supports the following operations
from the structural and functional project views:
Via the import function, reuse in the current project any part of a project created b
previously
Via the export function, copying any part of the current project to a le for b
subsequent reuse
The les generated during export are generally in XML format (1). However, in
addition to XML, variables can be exported and imported in the following formats:
.xvm format compatible with OFS data server software b
Source format, in an .scy le compatible with PL7 development software b
Text format with separator (TAB) in a .txt le for compatibility with any other system b
During an import, a wizard can be used to reassign data to new instances of:
DFBs
b
DDTs

In addition, when a functional module is imported, the data associated with
animation tables and runtime screens is also reassigned.
The XML import function also supports the transfer of a Modicon

PLC conguration prepared in the SIS Pro costing and conguration
tool, for use when creating a project in Unity Pro. This import function spares the
user from having to redene the PLC conguration when the PLC has already been
congured with the SIS Pro tool.
(1) XML language is an open, text-based language that provides structural and semantic
information.
