How do I flash an Exec into a Twido controller?

Published date: 30 April 2019

Goals and Symptoms

This resolution is to show how to flash the Exec into a Twido controller using TwidoSoft V3.5 or TwidoSuite V1.2

Causes and Fixes

The Exec on the Twido controller could be flashed using either TwidoSoft or TwidoSuite programming software.
First, launch either TwidoSoft or TwidoSuite.
From TwidoSoft, open "Update PLC microprogram" which is under the Tools menu (see below for illustration).



From TwidoSuite, open "PLC firmware update" (see below for illustration).



Once the Update PLC microprogram/PLC firmware update is launched, it opens Twido Windows Executive Loader
Wizard. Step 1 of 4, click on Next (see below for illustration).



In Step 2 of 4, browse to the Exec file you are trying to flash to the Twido and choose the type of connection. The
connection will depend on how you are connected to your Twido, choose either USB or COM* (serial) then click on
Next (see below for illustration). *please note* The TSXPCX3030 will show up as USB, but the TSXCUSB485
& TSXCRJMD25 will show up as COM* (depending on which COM port was assigned to that converter).



In Step 3 of 4, The Twido Exec loader performs a comparison between your chosen Exec file and the Exec that's in the Twido
controller to make sure that they are compatible. If the hardware ID's do not match, you will not
be able to flash the Twido. Make sure that the Twido Controller is stopped, then click on Next (see below
for illustration).



In Step 4 of 4, The Twido Exec Loader flashes the Exec on the Twido controller (see below for illustration).
MAKE SURE THAT YOU DO NOT POWER DOWN OR DISCONNECT POWER TO THE TWIDO
AFTER THE TRANSFER BEGINS. THIS COULD DAMAGE THE TWIDO.




Once the transfer is complete, a popup window will ask you if you want to flash another Exec.
Click NO and close the Twido Exec Loader program. It is recommended to Cycle power to
the CPU after loading an Exec before putting it back into commision.
