Support for Array Variables in Ladder, ST, and SFC Programs
Previous version (version 7.0) New version (version 7.2)
Array variables could be used for internal
variables and input-output variables in a
function block’s algorithm, but array variables
could not be used in programs (tasks).
Array variables can be specified even in programs (tasks) written in
ladder, ST, or SFC language.
This feature allows multiple variables with the same data
characteristics to be managed as a group.
•
Comparing Function Block Definitions
Previous version (version 7.0) New version (version 7.2)
Function block definitions could not be
compared.
Function block definitions can be compared in detail.
This feature makes it easy to check for differences between the
programs in function block definitions.
•
Comparison of Function Block Definitions, ST Programs, and Action Programs/Transition
Programs/Subcharts in SFC Programs
Previous version (version 7.0) New version (version 7.2)
ST programs and SFC programs could not be
compared.
ST programs and SFC programs can be compared.
ST programs in an SFC program can also be compared in detail.
PLC-PT Integrated Simulation
The following improvements have been made to the simultaneous interactive
debugging function (integrated simulation), which debugs operation between the
CX-Programmer’s ladder program and NS-series PT touch panel test screens in
the CX-Designer.
•
Starting Integrated Simulator from the CX-Programmer
Previous version (version 7.0) New version (version 7.2)
The integrated simulator could be started from
the CX-Designer only; it could not be started
from the CX-Programmer.
The integrated simulator can be started from the CX-Programmer
(specifying a saved CX-Designer screen file).
With this feature, it is possible to easily confirm the interaction
between a ladder program being edited in the CX-Programmer and
NS-series PT touch panel test screens.
•
Simulating the Occurrence of PLC Errors
Previous version (version 7.0) New version (version 7.2)
During simulation, it was not possible to
generate PLC system errors by manipulating
the corresponding Auxiliary Area flags. (The
system error flags were write-protected.)
It was necessary to create ladder programming
that generated errors using the FAL and FALS
instructions, and check operation in the
simulation.
PLC system errors can be generated during CX-Programmer ladder
program simulation by selecting Simulation - PLC Error Simulator
and writing the corresponding system error flags in the Auxiliary
Area.
With this feature, it is not necessary to create ladder programming
to generate errors. Also, it is easy to check the operation of the
ladder program and NS-series touch panel when PLC errors occur.
Improvements to Symbol Tables
•
Improved Interaction of the CX-Designer with Symbol Table Data
Previous version (version 7.0) New version (version 7.2)
Symbol tables could be copied and pasted from
the CX-Programmer to the CX-Designer, but
not the opposite direction.
Consequently, when NS-series touch panel test
screens were being edited in the CX-Designer
and I/O comments were edited in the CX-
Designer symbol table, it was necessary to
write the data in Excel and transfer it to the CX-
Programmer’s symbol table.
Symbol tables can be copied in pasted in both directions between
the CX-Designer and CX-Programmer.
This feature makes it easy to reflect changes to the CX-Designer’s
symbol table, such as edited I/O comments, in the CX-
Programmer’s symbol table.
