Filling unit of a container filling machine, having improved communication capability

摘要

A filling unit (10) of a filling machine (1) engages at least one container (2) to carry out filling thereof with a filling product, and is provided with an electronic control module (20), integrating a computing unit (22), and a communication interface (28), coupled to a communication bus (32) for communication with a central control unit (30). The computing unit (22) autonomously and independently initiates communication with the central control unit (30) over the communication bus (32), and asynchronously issues one or more interrupts (INT) over the communication bus (32) in order to communicate with the central control unit (30).
