The target the general of the present thesis was: constructing, installing and implementing with a programmable logical control (PLC), to a prototype for filling of large bottles with water. Coming true ad hoc a revision detailed on the languages more used (ladder and FDB) in the programming of a PLC. Straightaway, came true the diagram ladder and the simulation of the filling of large bottles with water took effect, this in turn allowed determining that the quantity of physical receipts and expenditures that were used in the PLC are: three entrances (I1, I2, and I3) and three physical exits (Q1, Q2 and Q3). At last, came true the performance testings of said prototype, the ones that it was used in three (3) sets of large bottles, with the following nominal volumes: five of 3.8 L, two of 4.5 L and three of 20 L; findings of fact in each case the following times filling: 8.1 s, 9.5 s and ...
