MULTIPROG® 4.0 PLC Programming System
Wide-ranging modifications even while PLC is running

With MULTIPROG® 4.0 Schleicher provides a convenient software tool for PLC programming microLine, XCx and ProNumeric/ProSycon controllers in Windows NT/2000/XP and 9x environments, as well as for automatic configuring of Schleicher XRIO I/O modules. The development environment supports all five IEC programming languages and also permits mixed programming in the graphic languages. 

The system can convert automatically between IL, LD and FBD, allowing different developers and service engineers each to use their preferred language on one and the same project.

With MULTIPROG® program modifications (including adding variables, instances or modules) are possible even when the PLC is running: The online display shows the active process in all the programming tool editors, while powerflow marks the active path. Project administration is conducted using MULTIPROG®’s central tree display, whose appearance and function are oriented on the familiar Windows Explorer. Commentaries can be maintained in several different languages, which can be switched as required online.

MULTIPROG® has an integrated OPC server for data access (specification 2.04) for integrating controllers on Windows PCs. A wide range of models, convenient edit wizards and other help functions allow you to create projects very quickly. For example, syntax is recognized on entry and marked in colour straight away. Flexible sorting and search functions support work with the variable editor. Complex data type structures are possible, including nested structures, arrays and strings.

Programmed modules can be saved in libraries or as a protected branch in the project tree, and provided with selective read, write and debug rights on the resource level. Of course Schleicher’s ready-made libraries are also available – from standard PLC functions through to powerful technology modules such as PID controllers.
