appeal particularly to engineers wishing to move from the
DOS-based MELSEC MEDOC programming package.
GPP/WIN gives the
user full support of the standard Windows functions such as copy
For example, sections can be copied within a program,
and finished program components copied from one project to
another for re-use.
Comment lists can also be transferred simply
to and from Excel, allowing for easy project documentation.
Multiple sessions of GPP/WIN can be run simultaneously, with the

network configurations and comment tables, making it easy for the
user to switch between any function by a simple click of the

comprehensive set of import filters enables the re-use of

To make commissioning and maintenance easy the PLC
program can be monitored in ladder diagram format and devices can
be monitored as decimal, hexadecimal or ASCII values.
changes of the program can be made when the PLC is in run mode
and devices forced, allowing for flexible program configuration
With GPP/WIN, networks can be configured
without the need for PLC code.
For example, to configure a
Mitsubishi CC-Link network with 2 slave units, users simply fill
in a table with number of slave station, type of station
(digital, analogue etc.) and the address of the devices where
data should be stored in the CPU.
All PLC parameters and network
configuration settings can be checked for plausibility on entry,
allowing even the most inexperienced programmer to create simple
or complex networks fast.
"Our objective is to make it
simple, straightforward and effective to move from DOS-based
MEDOC programming to the Windows environment offered by GPP/WIN.
Programmers making the transfer will find they can use the same
keystrokes, reducing both training effort and
implementation," says marketing manager David Folley,
