Previous version (Ver. 6.1) New version (Ver. 7.0)
There were no text-processing functions for
the ST language.
To process text for message displays and
no-protocol communications in the ladder
language, the user had to know the length of
the ASCII string and execute instructions
such as text-processing instructions, data
conversion instructions, and serial
communications instructions.
Note: The user can input text strings can in
I/O memory using the CX-
Programmer’s PLC memory function,
but it is necessary to know the data
size in I/O memory.
Text-processing functions (extracting text, merging, searching, etc.) are
supported for the ST language. With these functions, it is easy to create
text strings and process displayed messages using ST language in a
function block without knowing the actual ASCII codes.
Support for Input-Output Variables
Previous version (Ver. 6.1) New version (Ver. 7.0)
Input-output variables were not supported in
function blocks. (Only input variables, internal
variables, and output variables could be used.)
Input-output variables can be used in function blocks.
Input variables could not be specified as arrays. Input-output variables can be specified as arrays.
Values are passed from input parameters to
input variables.
Addresses (not values) are passed from input parameters to input
variables. Consequently, array input-output variables can be used in
the function blocks and large amounts of data can be passed easily
to the function blocks through input parameters.
Support for C500/C120/C**P Backup Function
Previous version (Ver. 6.1) New version (Ver. 7.0)
The programs in C500/C120/C**P PLCs could
not be managed online from the CX-
Programmer.
A program stored in a C500/C120/C**P PLC can be uploaded and
converted to a CS/CJ/CP Series program or CVM1/CV Series PLC
program. If an instruction’s specifications are different, a comment is
displayed to alert the user of the differences when the program is
converted. To convert a program, select Tools – C500/C120/CxxP
Support – Online PLC Program Conversion .
Program and I/O memory data (DM and HR) stored in a
C500/C120/C**P PLC can be backed up. Later, the backed up
program and I/O memory data can be restored to a C500/C120/C**P
PLC. To backup or restore the data, select Tools – C500/C120/CxxP
Support – Backup from PLC or Tools – C500/C120/CxxP Support
– Restore to PLC .
Program and I/O memory data (DM and HR) stored in a specified file
can be compared to the program and I/O memory data (DM and HR)
in a C500/C120/C**P PLC. To compare the data, select Tools –
C500/C120/CxxP Support – Compare PLC and file .
Improvements in Data Trace/Time Chart Monitoring
Previous version (Ver. 6.1) New version (Ver. 7.0)
Only one word of data could be specified at the
trace data for data tracing and timechart
monitoring.
Up to eight words of data can be specified at the trace data for data
tracing and timechart monitoring.
