Batch Error, releasing equipments
We have one repetitive problem with 800XA batch , we have one Ac800M controller.
and 800xa 5.1 reva .
the problem is that sometimes, the equipment is released for batch recipe, but the status in controller still remains adquired by the recipe, so this is one blocking for new recipes because the new recipe try to adquire the equipment and equipment in this moment goes to fail mode (red color), and it is not possible to release this equipment using the buttons in the equipment overview.
we try everything, but it does not release, so the only solution is to download cold start mode the application, in this moment we can use the buttons to manually release this equipment and recipe can start normally.
What could be the problem in this case?
waht to do to prevent this happens again?
I atach some pictures to show the problem
We begin check the equipment with problems, we begin to delete parts of equipment, and in each time we delete one part we run the one test recipe, until we discover one phase with problems.
in control builder this phase have one default function (clear state) that was running many times but we was not using this function in our program.
we delete this function and this remedy this problem.
so my suggestion is try with one copy of your equipment with problems and run one test recipe, check all phases verifying for this functions (clear state that are defualt)
Thanks for the fast answer.
I found the problem in my application. One of the operators left one phase in manual mode on the unit during the last procedure. This blocked the possibility to release the unit or discard it. As soon as the phase was but back to auto the unit also got released.
