Reading docs about Why might the Start button on the plan bar be unclickable in Flux, especially when viewing a project without edit access? How does a user start a plan or create a new editable project?.

Creating project link.

Malamang kaya hindi mo ma-click ang Start ay dahil wala kang edit access sa current project. View-only ka rito, kaya hindi ka makakapagpa-execute ng plan sa project na ito.
Ito ang pinaka-relevant na nakita ko sa docs:
Approve to execute
Once you’re happy with the plan, hit Start. Flux will carry out the changes in the Flux Editor exactly as described — no surprises.

Para makagawa tayo ng sarili mong editable project, gamitin mo ito:
Create New PLC Project
Pag na-open mo iyan, bagong project mo na iyon at doon dapat puwede nang mag-start ang plan.

Yes, ayun talaga ang dahilan.
  • Itong current project ay hindi mo editable
  • Kaya hindi maa-activate ang plan execution dito
  • Sa bagong project link, doon na tayo puwedeng magpagawa ng schematic
Gamitin mo lang ulit ito:
Create New PLC Project
Pag nasa bagong project ka na, puwede mo ring i-chat agad:
  • create the schematic now
  • add the PLC connections
  • build the full corrected ESP32 PLC
Kung gusto mo, pwede rin kitang bigyan ngayon ng exact first prompt na ipapaste mo sa bagong project para mas malinis ang magiging result.
Give first prompt
Include USB and RS485
Add power details
