General Presentation
Introduction The PL7 software allows for the installation of application-specific functions in software form (DISCRETE, analog, process control, weighing, 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).
z
An application-specific function on Premium is presented, depending on the application, in the form of: z a module (e.g.: counting application), a built-in interface (e.g.: communication port).

Programming Programming of the function to be carried out using: z bit and word objects associated with the module, z application-specific instructions.

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: z standard PL7 tools: z pull-down menus, z z z status bars, tool bars, editors, z

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.

General
Configuration of an application-specific function.
Introduction The Configuration function makes it possible to define the operating characteristics of the module or the application-specific interface.
This function is carried out from the PL7 configuration editor: z in local mode, z in online mode when the application is stored in non-write protected RAM (limited to certain parameters).
Note: The configuration parameters are not modifiable by program.
Illustration The screen below is an example of a configuration screen of an application-specific module (application-specific module TSY CTY 4A).

Confirmation
General
The characteristics defined in the configuration screen must be subject to a global confirmation of the application. This may be done: z z in local mode, so that the modifications are taken into account, in online mode in order to: z update the configuration parameters in the PLC, z reconfigure the channel of the module with its new parameters (the adjustment parameters return to their initial value).

General
Adjustment of an application-specific function
Introduction The Adjustment function allows the operating parameters of the applicationspecific module or interface to be displayed and modified, when they are modifiable.
This function is carried out from the PL7 adjustment editor: z in local mode, in order to define the initial parameters (value of the parameters during setup or on a cold restart), z in online mode, in order to define the current parameters (values lost upon cold restart if they have not been saved in advance).
Note: The adjustment parameters are modifiable by program.
Illustration The screen below is an example of an adjustment screen of an application-specific module (application-specific module TSY CTY 4A).

Debugging an application-specific function
Introduction
Illustration
The Debug function of the module or the built-in application-specific interface provides the tools to help with debugging of the application-specific function such as: z z display of module channel status, display of possible faults, z z z control of language objects, and, in the event of a fault, access to the module or channel diagnostics,
...
This function is carried out in online mode , with the PLC in STOP or in RUN, from the PL7 debug editor.

(application-specific module TSX DSY 08R5).
