What is PLECS Blockset and Why You Need a License File




PLECS Blockset is a product of Plexim, a company that develops software solutions for power electronics engineering. PLECS stands for Piecewise Linear Electrical Circuit Simulation, which is the core technology behind the software. PLECS Blockset integrates seamlessly with MATLAB and Simulink, allowing you to model and simulate complex power electronic systems in a familiar environment.


PLECS Blockset Features and Benefits




Some of the main features and benefits of PLECS Blockset are:


  • It offers a comprehensive component library that covers the electrical, magnetic, thermal, and mechanical aspects of power conversion systems and their controls.



  • It provides an intuitive schematic editor that lets you create circuit diagrams by dragging and dropping components and drawing wires.



  • It uses an ideal switch model for transistors and dynamically selects integration time steps before and after an instantaneous change in transistor resistance. This results in faster simulation speed and higher accuracy than traditional circuit-level simulations.



  • It supports both variable- and fixed-time step solvers from Simulink, as well as various analysis tools such as steady-state operating points, open-loop and closed-loop transfer functions, state space matrices, etc.



  • It allows you to design multi-domain systems by combining electrical circuits with mechanical, thermal, or magnetic components.



  • It enables you to create custom components and subsystems, as well as use C-script or DLL blocks for user-defined functions.



  • It supports code generation for real-time applications using PLECS Coder or Embedded Coder.



PLECS Blockset License Types and Options




To use PLECS Blockset, you need a license file that matches your MATLAB version, operating system, computer name, and MAC address. The license file also determines which products and features will be enabled in your software. There are different types of licenses available for PLECS Blockset, such as:


  • Floating license: A floating license can be shared among multiple users on a network. The license server manages the distribution of licenses to the clients. A floating license requires an internet connection or a local network connection to the license server.



  • Node-locked license: A node-locked license is tied to a specific computer. The license file is stored on the computer where PLECS Blockset is installed. A node-locked license does not require an internet connection or a network connection to the license server.



  • Trial license: A trial license is a time-limited license that allows you to evaluate PLECS Blockset for free for 90 days. A trial license can be requested from the Plexim website or from the PLECS installation wizard.



  • Student license: A student license is a discounted license that is available for students enrolled in an academic institution. A student license is valid for one year and can be renewed. A student license requires an internet connection or a network connection to the license server.



  • Academic license: An academic license is a discounted license that is available for faculty and staff members of an academic institution. An academic license can be either floating or node-locked, depending on the preference of the institution. An academic license requires an internet connection or a network connection to the license server.



  • Commercial license: A commercial license is a full-featured license that is available for industrial customers. A commercial license can be either floating or node-locked, depending on the preference of the customer. A commercial license requires an internet connection or a network connection to the license server.



How to Download PLECS Blockset Package File




To install PLECS Blockset, you need to download the package file that contains the software and the documentation. The package file is a ZIP file that has a name like plecs-blockset-x.y.z-win64.zip, where x.y.z is the version number and win64 is the operating system. You can download the package file from the Plexim website or from the PLECS installation wizard.

In this section, we will show you how to troubleshoot some common license issues and how to contact PLECS support for help.


Common License Errors and Solutions




Here are some of the common license errors that you may encounter when using PLECS Blockset and their possible solutions:


  • Error: License file not found. Solution: Make sure that you have copied the license file to the correct location on your computer or that you have entered the correct name or IP address of your license server. The default location for the license file is C:\Program Files\Plexim\PLECS Blockset\license.dat for node-locked licenses and C:\Program Files\Plexim\PLECS Blockset\license_server.dat for floating licenses. You can also specify a different location for the license file by setting the environment variable PLECS_LICENSE_FILE.



  • Error: License file expired. Solution: Check the expiration date of your license file by opening it with a text editor. If your license file has expired, you need to request a new one from Plexim or renew your subscription. You can also request a trial license from the PLECS installation wizard or from the Plexim website if you want to evaluate PLECS Blockset for free for 90 days.



  • Error: License file corrupted or invalid. Solution: Make sure that you have downloaded the correct license file that matches your MATLAB version, operating system, computer name, and MAC address. Do not modify or rename the license file in any way. If your license file is corrupted or invalid, you need to request a new one from Plexim or download it again from the link that was sent to you by email.



  • Error: License server not running or not reachable. Solution: Make sure that your license server is running and that you have a stable internet connection or a local network connection to the license server. You can check the status of your license server by using the lmutil command-line tool or the LMTOOLS graphical user interface. If your license server is not running or not reachable, you need to contact your system administrator or Plexim support for assistance.
