POWERPRO PROGRAMMING SOFTWARE
In complete accordance with IEC61131-3 international programming standard, PowerPro is a comprehensive, Windows-based programming software tool for LK series PLC. It provides an offline simulation feature that allows programmers to simulate, test, and debug the programming logic before the actual “live” implementation. This makes programming much easier and more convenient since it is not required to connect the PLC and download the programming codes to the hardware devices.
FEATURES
Programming Languages fully comply with IEC61131-3 Industrial Standard
- Supporting 6 types of programming languages editor
- Instruction List (IL)
- Structural Text (ST)
- Function Block Diagram (FBD)
- Ladder Diagram (LD)
- Sequence Function Chart (SFC)
- Continuous Function Chart (CFC)
- Depending on variable requirements, programmers can choose the relevant programming languages to work with. While working with FBD, LD, or IL, programmers are allowed to switch in between these programming languages.
Integrated Simulation
- Debugging of application program without hardware is possible with the buildin simulation feature of PowerPro. The application program can be checked before it is downloaded to the PLC.
- Showing all the variable values declared in the declaration part of each editor.
- All the inputs and outputs can also be simulated.
|
Hundreds of Instructions and Function Blocks
- Over 400 instructions and function blocks to be employed according to variable requirements of user.
- Common instructions include arithmetic, evaluation, boolean, shift, selection, compare, data type conversion, addressing, call, strings and etc.
- Common function blocks include enhanced PID controller, signal generator, function manipulator, analog processing, Modbus, ProfiBus, Ethernet, real-time clock, and watchdog, etc.
User Defined libraries
- Customized libraries can be easily created.
