Chapter 1 Prod uct Introduction 1_ Software Features 1. Complying with IEC 61131-3 The AH Motio n CPU compli es with IEC 61 131-3 editing environment which supports various pro gramming languages, multiple function blocks, tasks, and symbol tables. The programming languages which are supported are, structured texts (ST), ladder diagrams (LD), sequential function charts (SFC), and Continuous Function Chart (CFC). You can select a programming language according to your preference and the convenience. The programming languages support one another so that the programs written by different users are related. 2.
Various function blocks* In addition to standard IEC61131-3 function blocks (including PLCopen motion control function blocks), we also offer various convenient function blocks (DFB). You can write the program frequently executed in a function block so that the program becomes more structured and can be executed more conveniently. The encryption function supported by ISPSoft provides the secrecy of function blocks for special businesses. The program inside a function block cannot be learned, and the patent of a business will not be infringed. *Note : A function block is a program element equipped with the operation function.
It is similar to a subroutine, and is a type of POU (Program Organization Unit). It cannot operate by itself, and has to be called through the program POU. After the related parameters are transmitted, the function defined by a function block is executed. Besides, the final operation result can be s ent to the d evice or variable used in the su perior POU after the execution of the function block is complete. 3. Task The user program supports 283 tasks at most: 32 cyclic tasks, 32 I/O interrupt tasks, 212 external interrupt tasks, 1 24V LV detection, 4 timed interrupt tasks, and 2 communication interrupt tasks.
Users can enable and disable a task during the execution of a program by means of TKON and TKOFF. 4. On-line debugging mode After a single instruction step has been complete, or after a breakpoint is specified, users can easily find the bug in the program by means of the on-line debugging mode supported by the AH Motion CPU. Note: Structured Text (ST) do not sup port on-line debugging mode, and se quential function char ts (SFC) programming support the debugging mode during the action and the transition. 1-5
