GRAFCET Studio is a Windows application which can be used to create/design a GRAFCET flow chart according to DIN EN 60848. This may then be simulated on a PC.
In addition, the GRAFCET which has been created may then be transferred to a device (i.e. a Programmable Logic Controller) at the touch of a button.
The GRAFCET flow chart therefore becomes a cross-platform GRAFCET programming language through GRAFCET Studio.
GRAFCET Studio = GRAFCET Editor + GRAFCET Simulator + GRAFCET programming software
GRAFCET Studio is a new Windows software which may be used on Windows 7/8/10.
The basis for GRAFCET Studio is the latest Microsoft technology for desktop programs: Windows Presentation Foundation (WPF). Because it uses WPF technology, GRAFCET Studio is high-performance and the user interface is infinitely scalable without any loss in quality.
The advantages of WPF technology:
GRAFCET Studio essentially consists of three components:
The GRAFCET is simulated using a sleek, high-performance Hybrid GRAFCET Engine. This is also be used on the external device.
The GRAFCET Engine requires only 40 KB of memory on the target device (sum of data and program).
It is therefore possible to use the GRAFCET Engine on even the smallest SIEMENS S7-1200 (which has 50 KB RAM).
Currently the following devices are supported by GRAFCET Studio:
The following are also in planning:

GRAFCET Engine is cross-platform. This means that the GRAFCET created using GRAFCET Studio can run on almost any device.
Are you device manufacturers? GRAFCET Engine is currently available in SCL source code and C#, C++ source code, so that porting can occur in a few days, depending on the target device.
The following device requirements exist for GRAFCET Engine:
GRAFCET Studio’s mode of operation is as follows, taking the example of a SIEMENS S7-1200:
GRAFCET Engine must firstly be installed on the S7-1200. The easiest way to do this is by using a template project:
In addition to the GRAFCET logic, the user can also write other functions using the TIA PORTAL if necessary: The GRAFCET logic and PLC user program may coexist and work in conjunction with one another.
Please note: GRAFCET Studio does not require the TIA PORTAL to transfer the GRAFCET to the control system.
GRAFCET Studio cannot totally replace the device manufacturer’s programming tool (i.e. TIA PORTAL, Simatic Manager) as the control system must firstly be prepared for GRAFCET Studio (project template, hardware configuration).
If the control system also unexpectedly stops or if the hardware configuration must be modified, the manufacturer’s programming tool is also required.
However: When the GRAFCET Engine is installed on the control system, the manufacturer’s programming tool may not be used as often or may not be used at all.
If you don't know what GRAFCET is, you should take a closer look.
With GRAFCET you can create very fast and efficient a sequence control system.
With little time you can learn GRAFCET- the learning curve is very steep.
GRAFCET is also part of the following training occupations in Germany:
Also in technical academic high schools (German "technische Gymnasien") GRAFCET is included in the curriculum.
In this way, the GRAFCET may be tested extensively in advance using a virtual system.
