Version 7.0 Upgrade Information
Functionality Improved from Version 6.1 to Version 7.0
Compatible PLC Models
The following PLC models have been added as compatible PLCs as part of the
version 6.1 to version 7.0 upgrade.
CS/CJ Series CPU Units with unit version Ver. 4.0 and higher
Ver. 4.0 and higher CS/CJ Series CPU Units are supported.
CP Series CPU Units
The CP Series CPU Units (CP1H-Y) are supported.
Support for NSJ-M3D Controllers
The NSJ @ - @@@@ (B)-M3D Controllers are supported.
Ladder Program to Function Block Conversion Function
Previous version (Ver. 6.1) New version (Ver. 7.0)
To convert existing ladder programming to a
function block, the ladder programming was
copied and pasted into a function block
definition. At that point, it was necessary to
check the variables and addresses used in
the program and manually register those
variables and addresses while organizing the
input variables, internal variables, and output
variables.
Existing ladder program sections can be easily converted to function
blocks by selecting the program circuits to be converted and selecting
Function Block (ladder) generation . The function block definition is
created automatically and the variables are allocated automatically
based on the usage of the variables and addresses in the program.
Online Editing of Function Blocks
Previous version (Ver. 6.1) New version (Ver. 7.0)
A function block definition (algorithm and
variable table) could not be edited while the
PLC program was being executed. (The
instance I/O parameters could be changed.)
A function block definition (algorithm and variable table) can be edited
while the PLC program is being executed. (Instances cannot be added.)
With this capability, it is possible to debug and edit the function block
definitions themselves even if the PLC must operate 24 hours/day
because there are devices that cannot be stopped. To edit a function
block, select the function block definition in the Workspace and select
FB Online Edit – Begin from the popup menu.
Note: Function block instances cannot be added.
Note: This function cannot be used for simulations on the CX-
Simulator.
STRING Data and Text-processing Functions Supported in ST-language Function Blocks
Previous version (Ver. 6.1) New version (Ver. 7.0)
The STRING data type could not be used in
the ST language. (See note.)
The STRING data type can be used as a data type in the ST language.
With this capability, it is easy to set a variable containing text (ASCII) in
another variable with a substitution operation (such as: a := ‘@READ’;).
In this case, it is not necessary to know the length of the ASCII text
string.
