Note
(1) The required memory (RAM) capacity is the capacity required to create
programs. If the computer’s memory is less than the required memory capacity, the CX-Programmer may operate slowly.
(2) Windows 95 cannot be used when connecting through a Controller Link
Support Board (PCI Card) or SYSMAC LINK Support Board (PCI Card).

Files Created with CX-Programmer IEC
Project Files (*.cxi)
Projects created in CX-Programmer IEC contain all of the program-related
data, such as function block definitions and programs with instances. The
data is stored as a file with a “cxi” filename extension.
The following diagram shows the contents of a project. The function block definitions are created at the same directory level as the program within the relevant PLC directory.

Each function block can be
stored in a separate
definition file (.cxf).
