A liquid registration and control system (30) has an intrinsically safe (IS) fiber optic network (56) for the transmission of digital data between various modules (42, 54, 58, 146) in the system (30). The system (30) modules (42, 54, 58, 146) are dedicated to various liquid delivery functions and operational capabilities and send messages to each other over the network (56). |
