General Presentation
Introduction The PL7 software allows for the installation of application-specific functions in software form (DISCRETE, analog, process control, etc.).
The application-specific functions are automated functions which interface with the control part (the PLC program) and the operational part (sensors, actuators and man/machine interfaces).
l l
An application-specific function on Micro is presented, depending on the application, in the form of: a module (e.g.: counting application), a built-in interface (e.g.: communication port).

General
The table below gives a short description of the general principle for the installation of an application-specific function. This principle will be covered again later in this manual in more specific detail for each application.

Phase Description
Configuration Configuration of the module or built-in interface
Symbolization Symbolization of variables associated with the application-specific function.
Programming Programming of the function to be carried out using: l l bit and word objects associated with the module, application-specific instructions.
Transfer Transferring the application to the PLC.
Documentation Printing of the different information about the application.
Debug Debugging the application (I/O control, fault identification).
Note: The order shown above is given as an indication only; the PL7 software allows the editors to be used interactively in the order required (however, the data or program editor cannot be used if the I/O modules have not been configured first).
An application-specific function is installed using: l standard PL7 tools: l pull-down menus, l l status bars, tool bars, l editors, l ...
application-specific screens, l l configuration screens, adjustment screens, l l debug screens, language objects giving program-based access to inputs and outputs of the module or built-in interface.
l instructions relative to the application-specific function, where applicable.
Note: The different screens as well as the objects associated with an applicationspecific module are accessible via the software as soon as the module is declared in the configuration, without it even being necessary to write a program line.
