A tale of woe...
Not work related, but i was 'fettling' an exit conveyor within a complex packing machine at work. Having welded some new guide rods,I wanted to limit the amount of vertical travel on the conveyor they were fitted to, i knew the settings would be in the PLC (computer) .
Into engineering mode, enter the passwords, now...begin searching for the relevent section in the parameters.
I'm learning the machines, never been in these particular parts of the PLC before, so steady goes eh ?
I found 'Standard Settings' in one page...hmmm, pressed it, expecting another page to open, but nothing. Phhh, its not there, sod it, exit out, i'll look later.
Half an hour later, they start the machine up, but its not working.....it begins to dawn on me...errrrr
that may be my fault.
Spent an hour reprogramming it up, saving as i went to flash memory, only to realise half way through there was a function ...'revert to previously saved confections' (or similar wording)
I'd reverted back to factory settings in the first place...reprogrammed it all manually....only to realise i could have got it all back with the press of another button.
Ah well....its a slow painful process when you're in at the deep end, usually without guidance or in depth training.
