License Manager

For Grafcet-Studio and PLC-Lab we offer the following License-Systems:

  1. Single license
  2. Network license (you need at least 5 licenses)
  3. Cloud license (you need at least 5 licenses)

Tip

With the cloud license an educational institution or a company can lend licenses to pupils/students/employees. See below.

Note

The descriptions of the network license and cloud license are only valid for the programs Grafcet-Studio and PLC-Lab.

Single License

Features

  • The license can never be lost as it is stored in the cloud.
  • If you have accidentally not deactivated the license on the old computer, you can still release the license with the new computer and then activate it.
  • Even if your hard drive is crashed or your computer has been stolen, you can move your license on another computer and then use it again. You only need your serial number of the software.

Important

An Internet connection is required for the following steps.

These instructions for the single license are valid for following programs:

  • GRAFCET Studio

Network license

Features of the network license

With the network license, a license server is installed on a computer in the local network. The computer must be a Windows PC because the license server is a Windows service.

If the license server is installed, it is activated via the license manager. An Internet connection is required for this process. After this activation, an Internet connection is no longer necessary.

The software can now be installed on all PCs in the local network. At startup, a license is requested via the network. If a license is free, it is taken from the license pool and the software can be used. If the software is terminated, the license is added to the license pool again.

The license server thus distributes the existing licenses within the local network (Floating licenses).

Advantages of the local license server:

  • Distribution of existing licenses within the local network
  • The client PCs do not have to be activated.
  • When using the licenses no Internet connection is required.

The license server is optional and can be purchased with 5 or more licenses.

If you have purchased a local license server, you have also received the installation instructions. If this is not the case, please contact support@mhj.de

Cloud license

Features of the cloud license

Similar to the local license server, the cloud license server also distributes the existing licenses (floating licenses).

The differences:

  • There is no license server to install, a server of MHJ-Software on the Internet is used.
  • The licenses can only be used if an Internet connection is available.
  • The licenses can be distributed worldwide.

With the cloud license the license owner can lend licenses to employees or students.

If you have purchased a cloud license server, you have also received the installation instructions. If this is not the case, please contact support@mhj.de
