There is described a packaging machine (1) for producing sealed packages (2) of a pourable food product from a strip (6) of heat-seal sheet packaging material. The packaging material (1) has a number of photocells (14), which are programmable externally as regards their setting parameters, are positioned facing the strip (6) of packaging material to detect optically detectable elements on the strip, and have setting means (26, 210, 300). The packaging machine (1) also has a control unit (16) connected to the photocells (14) and having enabling means (24) for enabling the setting means of a specific photocell (14), data downloading means (26, 240, 310) for downloading off the specific photocell (14) the setting parameters of the photocell, and data uploading means (26, 260, 330) for uploading onto the other photocells (14) setting parameters calculated as a function of the setting parameters downloaded off the specific photocell (14).

A setting method as claimed in claim 16, for a packaging machine comprising a number of said photocells; wherein said programming step comprises the steps of downloading off a specific one of said photocells the photocell operating parameters of the photocell, and uploading onto at least one of the other photocells photocell operating parameters correlated to the photocell operating parameters downloaded off said specific photocell.21. A setting method as claimed in claim 20, wherein said step of uploading onto at least one of the other photocells photocell operating parameters correlated to the photocell operating parameters downloaded off said specific photocell comprises the step of uploading said photocell operating parameters onto all the photocells of said packaging machine.22. A setting method as claimed in claim 20, wherein said programming step also comprises the step of controlling said specific photocell to enable a setting procedure of the photocell.23. The method of claim 16, wherein the photocell operating parameters include a static intervention threshold.24. The method of claim 16, wherein the photocell operating parameters include a dynamic intervention threshold.25. The method of claim 16, wherein the photocell operating parameters include a static photocell operating mode.26. The method of claim 16, wherein the photocell operating parameters include a dynamic photocell operating mode.27. The method of claim 16, wherein the photocell operating parameters include a light spot color.28. The method of claim 16, wherein the photocell operating parameters include a signal deviation.29. The method of claim 16, wherein the photocell operating parameters include an enabled/disabled state of a teach-in procedure.
