Twido™ Firmware
Overview
The Twido™ Windows Executive Loader Wizard is a Windows-based program that guides you through the steps needed to update the Firmware Executive in your Schneider Electric Twido programmable controller. The Firmware Executive is the operating system that runs your applications and manages controller operation. The wizard provides an intuitive point-and-click interface that progressively steps you through the updating procedure to quickly download the latest version of the executive for your controller.
See the Executive Loader Wizard User Guide for detailed instructions. This guide is available by clicking on the help button for any of the Exec Loader screens.
Opening the Exec Loader Wizard
You can open the Executive Loader Wizard from TwidoSoft by selecting Tools® Update Firmware Executive ( Update PLC microprogram in v2.1) from the main menu, or by double-clicking on the program to open it directly. The wizard program, TWEL.EXE, is included in the TwidoSoft installation and can be found in the default install directory
