Simple, flexible and economical, Winlog is a real time SCADA/HMI software package for the supervision of industrial and civil plants. An integrated development environment provides different tools (Gate Builder, Template Builder, Code Builder) for the easy and intuitive creation of multilanguage applications. Communication with most available devices (PLCs, controllers, motor drives, data acquisition modules, etc.) is ensured by an extensive library of drivers; special functions can be developed and integrated directly by the user; export functions allow recorded data to be accessed from main software packages (Excel, Access, etc.). With Winlog it is possible to set up a distributed architecture based on Intranet/Internet and to use the fix and mobile (GSM) telephone network to communicate with remote devices or to send SMS. Winlog is offered at a very competitive price, and is backed up by a personalised assistance service for every customer.

A unique low cost run-time key can be used to run any of the applications, independently of the number of tags involved. Multilanguage applications (in two languages or more) can be set up, with a simple command to switch between languages. Reports and historical data can be recorded in a format that can be accessed directly from other software packages (Excel, Access, etc.).

Distributed Client/Server architectures can be set up using a TCP/IP protocol and a Intranet/Internet network. Multi-master structures, in which each terminal can communicate with the others so as to allow both reading and writing, are also possible. Both the fix and mobile (GSM) telephone network can be used to communicate with remote devices or to send SMS to maintenance operators; in this way a supervision centre can provide a remote assistance service to a network of peripheral sites spread around the country.

Historical or online trends can be displayed individually or in groups: up to ten trends at a time are possible, which can refer to different kinds of tags, each with its own colour and scale. The temporal axis can be shifted backwards and forwards using video icons, the mouse can be used to zoom in and out, and various other viewing options are possible (grids, line thicknesses, modes of interpolation, etc.).

Events and alarms can be activated as a function of the values taken on by associated tags: alarms are signalled immediately in a specially reserved area of the screen, and the confirmation by the operator is also controlled. Status information (active events) and history (date, time, event) can be accessed according to various freely definable categories (eg. priority and location).

The recipes are sets of characteristic values of a working process or a plant configuration: new recipes can be created and existing ones updated (copied, deleted, renamed, printed and modified), as well as being imported and exported to and from the process itself. The application of a recipe can be commanded by the operator, automatically executed on start-up, or triggered by the program (eg. batch process).

Reports with summary information about production data or process quality or plant alarms can be generated in a pre-programmed format and can be displayed or printed or sent to any peripheral device. Reports can be either requested by the operator, or automatically generated on a cyclic basis (after a specific time interval, on a particular day of the week, etc.), or triggered by the program (eg. in case of end of production ). Copies of reports are also recorded in history files and can be accessed by other software packages (Excel, Access, etc.).

Each menu item, template, tag, etc., can be protected by the specification of the groups authorized to access it and those who can modify it. A name, password, and member-ship of one or more groups can then be defined for an unlimited number of operators. Every operator's action that has produced a data modification is recorded in a history file by date, time, event description and operator's name.
