A control system () for a device () for making possible a process control for a process carried out on the device, with a reception module () and with a processing module (). The reception module is configured to receive process information (). The process information pertains to currently carried out process steps () of the process. The processing module is configured to assign a sequence number () to the received process information and to generate a visible protocol signature () based on the sequence number, of the process information, of time information () and a secret system code () and to assign it to the process information, and to output the process information with the assigned visible protocol signature. The secret system code is stored n this case exclusively in an internal memory () of the control system.

Control system for a process control

A network device () detects a network problem in a medical system (). A reception module () receives current medical system process data. A monitoring module () detects predefined events () based on the process data and triggers a detection signal () output in the presence of a predefined event. A sending module () sends the detection signal to a predefined device address () via a network (). The predefined events include: a predefined plurality of unsuccessful password entry attempts within a predefined first time period; an unsuccessful encryption within an encryption protocol framework; a predefined plurality of outputs via the network triggered via the network within a predefined second time period; an output of a signal, which is to be carried out, has been unsuccessful; and a predefined number of messages have been received within the framework of a service discovery within a predefined third time period.

Network device and medical system for the detection of at least one network problem

A testing system, a testing process, a medical device, e.g., an anesthesia device (G), and a computer program product are provided for testing installed program versions for acceptability. The anesthesia device (G) comprises a plurality of electronic components (K), which are operated and/or controlled with a program, which may have various versions. A release function () is activated for releasing the anesthesia device (G) or for putting same into operation only if a consistent set of acceptable program versions can be detected, and the anesthesia device (G) is otherwise blocked.

Version control for medical anesthesia devices

A licensing system is provided for transferring license information for at least one license-requiring software component of software-controlled devices. The licensing system comprises a first, portable license data storage medium (), which is provided with a processor unit () and on which at least one license information for the at least one license-requiring software component is stored in a memory unit (). A second, exchangeable license data storage medium () is provided with a processor unit (). A data transfer channel () is provided for transferring data between the first license data storage medium () and the second license data storage medium (). A license detection device () is provided which can poll the at least one license information of the first license data storage medium () and transfer same to the second license data storage medium () via the data transfer channel (). The at least one license information can be stored in a memory unit () of the second license data storage medium () and cannot subsequently be polled any longer on the first license data storage medium (). A license-providing device () is provided which can make available or transfer the at least one license information stored in the memory unit () to the software-controlled device () for releasing or blocking the at least one license-requiring software component.
