PNC

Leomatic PNC modular systems (PLC+CNC), ideal as real-time field-electronic, are based on an "embedded" CPU card (LEOMATIC P41 or P51S); it provides the direction over the system and can be directly connected to an external Windows PC, also for service. This serial connection may be of type RS232, RS422 or RS485 (networks are possible).
A PC may so be used for the PNC configuration, data and parameters programming, test of application software (PLC). If a man-machine-interface (MMI) is needed, you can develop it (using Leomatic free SW libraries) and run it on the same PC.

Leomatic supplies to any software developer, free of charge, a Windows software suite including the WinPncLib library and several ActiveX controls. They handle:
- the communication between PC and PNC rack;
- data exchange necessary for a SCADA interface;
- the PNC configuration (quantity and type of present cards);
- data and parameters programming, recipes, ...;
- monitoring and test of firmware variables and of all hardware resources (axes, I/O, ...);
- the on-board firmware download for any card. 

WinPncLib library is supplied as dll kit for MFC based application under operating system Windows 95, 98, Me, 2000, XP. It is accomplished with a user's manual.
ActiveX controls, based on WinPncLib library, give the programmer access to any basic function of the library but also offer many high-level methods.

PncTool utility is a dedicated software tool, developed and freely supplied by Leomatic.
It uses WinPncLib and all ActiveX controls, so that it allows:

• handling an archive of configuration data-files;
• advanced programming of all parameters of the axes control cards;
• calibration (auto-zero) and adjusting of any axis;
• programming of work-cycles using ISO language;
• monitoring of system and application errors;
• graphic representation (oscilloscope like) of any firmware variable in respect of time or of another variable.

Automation Builder is a new dedicated software tool, still under development.
It will group all the functions of PncTool and of LeoPlc, allowing more practical and faster sessions of programming and debug.
It is actually available a version with the only functions of LeoPlc, in a modern context.
They appear particularly progressive as "skin", use and productivity; you can easily develop your own machine logic-program (PLC). 

For each single card, Leomatic supplies an open software library; it allows to handle all of its functions and to develop an applicative operator's interface.
You may freely download these libraries from the page Download.

Each card is normally supplied with:

• a hardware manual;
• a software user's manual;
• a software library, in standard C language;
• an ActiveX control, useful for a quick development of a Windows application software acting as control and interface;
• source "demo" files, in C / C++ / Visual Basic languages, showing an example on how to use the software library;
• a simple test program of the card.
