Abstract
A device access means for accessing fieldbus components of a fieldbus system is described. The device access means is installed in a host or host environment and includes a frame application as well as, bound into the frame application, at least one driver, which is designed to access at least one fieldbus component. Moreover, the device access means includes a monitoring unit, which is designed to register information concerning resources reserved by drivers and provided by the operating system of the host or host environment, and, upon detecting an abnormal temporal increase of resources reserved by drivers, to initiate at least one predetermined countermeasure.

1-16. (canceled)
A device access means for accessing fieldbus components of a fieldbus system, wherein the device access means is installed in a host or a host environment, the device access means comprising:
- a frame application;
- and,
- at least driver bound into the frame application, wherein the at least one driver is designed to access at least one fieldbus component,
- wherein the device access means includes a monitoring unit designed to register information concerning resources reserved by drivers and provided by the operating system of the host or the host environment, and, upon detecting an abnormal temporal increase of resources reserved by drivers, to initiate at least one predetermined countermeasure.
A system of automation technology, comprising:
- a fieldbus system having at least one fieldbus component;
- and
- a device access means which is installed in a host or host environment, wherein the device access means includes:
- a frame application;
- and
- bound into the frame application, at least one driver which is designed to access at least one fieldbus component of the fieldbus system,
- wherein the system includes a monitoring unit which is designed to register information concerning resources reserved by the drivers and provided by the operating system of the host or host environment, and to initiate at least one predetermined countermeasure upon detecting an abnormal temporal increase of resources reserved by the drivers.
A method for monitoring operation of a device access means which is installed in a host or host environment, wherein the device access means is designed to access fieldbus components of a fieldbus system, wherein the device access means includes:
- a frame application, and
- at least one driver bound into the frame application and designed to access at least one fieldbus component of the fieldbus system, the method comprising:
- registering information concerning resources reserved by drivers and provided by the operating system of the host or host environment;
- evaluating a temporal course of resources reserved by drivers;
- and
- in the case of ascertaining an abnormal temporal increase of resources reserved by drivers, initiating at least one predetermined countermeasure.
