Fanuc Ladder Software FAPT III

Fanuc PMC software is developed by FANUC CORPORATION, JAPAN. FANUC is a worldwide leader in CNC controllers and robotics. This software is used to create sequence programs for FANUC PMCs. Here PMC stands for Programmable Machine Controller.

PMC is inside the CNC, it will control the sequence for different operations of CNC machine like turret rotation, servo axes movement, spindle motor forward/reverse and any operations required for CNC machines.

The sequence is performed step by step as required by the CNC machine, so it is written in a ladder logic format. Ladder language programming is a widely used PMC programming language. It uses I/O signal addresses to execute the sequence program.

FANUC FAPT PMC SOFTWARE is developed for Microsoft Windows Systems. The software can be used on a single computer, if you want to use it on multiple computers, you need to purchase a license from FANUC.

Key functions:

As FANUC software is windows based software, hence it is user friendly for creating sequence programs. Sequence programs are also called ladder logic programs. The main key functions of software are as below:

  1. The software will upload ladder program from the computer to CNC and download the ladder program from CNC to the computer via RS 232 or Ethernet.
  2. A new ladder program can be created through this software and modify or change the existing ladder program.
  3. You can read and study the FANUC ladder file in this software.
  4. The software will convert the memory card format (Compact Flash card) ladder program into a FANUC FAPT ladder III readable format. This function is called the importing ladder program.
  5. The software will be used to export from FANUC FAPT ladder III readable format ladder file into memory card format file.
  6. This software is used to simulate PLC program with a CNC machine, which means we can monitor PLC signal status in software online, debug the PLC program.
  7. Print the ladder of a particular machine for documentation.
