Abstract: Sections (22) of an I.S. glass forming machine (23) have a plurality of mechanisms which can be respectively driven by a first drive. Each first drive is allocated a controller which is connected to a first sequencer (60) via a first bus (59). All first sequencers (60) are connected to a second bus (70) to which a second sequencer (71), a manually-operated device (72), a PC (73) with an Internet connection (74) and a modem (75) are connected. Peripheral devices of the I.S. glass forming machine (23) each have at least one third drive (5, 7, 9, 11, 15, 21, 32, 41, 42, 43, 50, 51, 52, 17, 82). Each third drive is connected to a first control device (77). In the case of the third drives (17, 82) associated first control devices (77) are directly connected to the second bus (70), whereas in the other cases a plurality of first control devices (77) are connected to a third bus (78) which is connected to the second bus (70) via a second control device (79).
