Version Upgrade Information

Version 8.0 to 8.1 Upgrade Information
Version 7.2 to 8.0 Upgrade Information
Version 7.0 to 7.2 Upgrade Information
Improved Support for
Function Blocks and
Structured Text
Support for ST Language in the Program (Task Allocation)
Version 7.0
The ST language could be used only in function
blocks.
Comparison of Function Block Definitions and ST Programs
Version 7.0
Function block definitions could not be com-
pared.
Refer to the CX-Programmer Operation Manual (W446) for information on
upgraded functions other than those for function blocks and structure text.
The new PLC models of CJ2H-CPU6@ supporting function blocks and struc-
tured text are now supported.
The new PLC models of CJ2H-CPU6@-EIP supporting function blocks and
structured text are now supported.
For details on the other improvements to CX-Programmer functions in this
upgrade, refer to the CX-Programmer Operation Manual (W446).

IEC61131-3 Language Improvements
Support has been improved for the structured text and SFC languages, which
are IEC61131-3 languages. Ladder, structured text (ST), and SFC program-
ming can be combined freely, so that the best language for each process can
be used, which reduces program development time and makes the program
easier to understand.
The ST language can be used in programs (task allocation) other than
function blocks. (ST programs can be allocated to tasks.)
Other programming languages can be combined freely in a single user
program. With this capability, numerical calculations can be written as
ST programs, and other processing can be written as ladder or SFC
programs.
Note Structured text is supported only by CS/CJ-series CPU Units with
unit version 4.0 or later. It is not supported by CP-series CPU
Units.
• Function block definitions can be compared. With this capability, it is
easy to check for differences in function block definitions in programs.
• ST programs can also be compared.
