Abstract
A device access apparatus for a client-server system is described, wherein the device access apparatus is used to access components of a field bus network. The device access apparatus includes a general application that is installable on a server and configured to interchange data with the components of the field bus network. The device access apparatus also includes a device driver that is installable on a client and a communication proxy that is installable on the server that are configured to set up a data connection between the server and the client. The data connection is used to transmit data between the device driver and one of the components of the field bus network that is associated with the device driver. The communication proxy is configured to monitor data traffic on the data connection between the client and the server and detect errors in the data transmission.
