摘要： The invention relates to a microprocessor-controlled standard field device (3', 4', 5', 6'), such as a measuring sensor or an actuator, for connecting to a field bus system (1) that, in turn, is connected to, for example, a freely programmable controller (2'). According to the invention, the field device (3', 4', 5', 6') is equipped with a security layer (10) for carrying out a security proven communication. A secure and simultaneously cost-effective communication with a control device (2) via a field bus system (1) is made possible by implementing a security layer (10) in a conventional operationally proven or redundant standard field device (3, 4, 5, 6).

摘要： Production plant featuring automatic making and packing machines (2), each of which has a relevant control unit (3); a collection computer (9) awaits receipt of information packages (P) transmitted independently and asynchronously by the control units over a first communication network (5; 8); and the collection computer (9) organizes and processes the information packages (P) received from the control units (3) to generate overall data (D) accessible over a second communication network (8), with respect to which the collection computer (9) acts as a server.
