GX Developer (SWMD5C-GPPW-E)
MELSEC Programming software
GX Developer is a powerful Windows based programming
software which replaces the previous DOS version MELSEC
MEDOC, GPPA and GPPQ software packages. However, GX
Developer is more than just an upgrade. By taking full
advantage of the Windows environment and adding many
useful functions, the GX Developer programming environ-
ment is easy to use and new program development is both
fast and efficient.
GX Developer supports programming of all current MELSEC
PLC CPUs, so project design using a variety of CPU types
and series is possible.
■ Programming languages
In addition to ladder and list programming languages, SFC
(MELSAP2/MELSAP3) is supported. With the Windows
environment, all these program types can be created and
edited easily with the mouse or keyboard.
■ Easy program creation and editing
GX Developer supports standard cut, copy and paste
operations. This allows greater ease of use and the ability
to edit data in other applications. For instance, comment
data can be edited in Word or Excel and directly pasted into
the comment edit screen.
■ Full diagnostic capability
In the event of an operation error online diagnostics can
quickly pin-point the problem. The GX Developer helpfile
further assists to resolve hardware and software problems
without the need for a manual.
■ CC-Link support
Operation monitoring, link status and testing have been
enabled with the A/QnA Series. The CC-Link unit’s link
status and error status can be monitored with the A Series/
QnA Series, and a line test to check for faulty stations can
be carried out. Also, the CC-Link personal computer
interface board (A80BDE-J61BT13) is also compatible with
GX Developer.
■ Backward compatibility
GX Developer not only supports downloading existing
projects from the PLC CPU but also allows direct conversion
of existing
DOS based software GPPA, GPPQ and MELSEC
MEDOC FXGP (Win) and FXGP (DOS) data.
■ Multi-windows, Multi sessions
Use of both multiple windows (e.g. different programs
within the same project) and multiple sessions (e.g. more
than one iteration of GX Developer running on a single PC)
gives greater scope to share common data between program
and projects quickly and easily. Also programming
productivity is enhanced with this function. For example, a
programmer can monitor one project while editing another.
■ Modem function
Communication is possible via the A6TEL modem interface
unit (A Series only) or the Q6TEL modem interface unit (A
Series/QnA Series). By using a modem, remote PLCs can be
serviced.
■ Software family
While GX Developer can be used by itself to create and
manage programs and projects, other software packages
have been produced to work in conjunction with GX
Developer, further enhancing programming and main-
tainability.
GX Simulator (SWMD5C-LLT-E)
MELSEC Simulation software
Programs can now be tested and checked without the need
to download to a CPU. This useful function allows
simulation of the sequence program within the Windows
environment. Program execution and timing can be easily
seen and because the display method is the same as the
standard monitoring function in GX Developer, the display
format is both familiar and easy to understand.
A timing chart can be displayed with the ladder logic test
tool function software package allowing program operation
to be confirmed graphically.
