PC WORX


PCWORX is the IEC-61131-based automation software from PHOENIX CONTACT. It is designed for the PC-based programmable controllers such as the Field Controller (FC) and the stand-alone Remote Field Controller (RFC/ILC) boards.



PCWORX combines tools for configuration, programming and visualization of machines and automation systems. It is suitable for use in distributed automation as well as for conventional central automation.
PCWORX offers up to five IEC-61131 programming languages:

  • Structured Text (ST)
  • Ladder (LD)
  • Instruction List (IL)
  • Function Block (FB)
  • Sequential Function Chart (SFC)

Multiple program languages can be mixed and matched within one project.

Open data interfaces eliminate redundant data entry and reduce the program development time. With the help of the optional IBS OPC Server or the new AX OPC Server, PCWORX can easily exchange data to any OPC-client software (e.g. HMI software).

The new PCWORX EXPRESS is a FREE programming tool specifically designed for the ILC1xx ETH series.

PCWORX EXPRESS is part of the new AX SW SUITE 2008 and does not require a software key. It supports up to 4,096 points (up to 64KB input data and 64KB output data). It has a simplified user interface and supports the following IEC61131 languages: Structured Text (ST), Ladder (LD), and Function Block (FB).
