good fellow, I present below a video (in Spanish) of the application made in cúcuta / Colombia. a counter tile production system where, thanks to a network of sensors installed you can post all production was implemented. part of this is calculated among other things:
machine cycles
lost time
effectiveness
square meter
format produced
break caused
ton consumed in production
lifespan of punches, dies
Spaces within the furnace
mimico of production
in the end
visualize all this is possible through
web server
sms
OPLC
email
and scada done by my using dde excel and vba
successes
