Good morning Gents
We have a filler for filling PET bottles with fizzy drinks.
Its getting old and drops a few bottles here and there which causes big jam ups and bends bits on the filler.
I am very good with Siemens Step7 but am new to PL5 software.
The bottles go in past a sensor which then puts a bit into a shift register, the bottle is then detected again as it leaves the filler and enters the capper which is then put into another shift register. Is there a function in the software with which i can monitor the shift register to spot if a bottle is suddenly missing from it when it leaves the filler to enter the capper? I can then use this to stop the machine.
Ive tried counting bottles in and out but by the time this has happened another 10 or so bottles have gone through still causing a jam up.
Many thanks
Kevin
