Abstract
The application relates to a data transmission system for a data exchange between a field bus system that includes at least one field device and device access software installed on a host. The data transmission system includes a coupler device connected to the field bus system and a generic communication driver integrated in the device access software. The data transmission system further includes a central data transmission path between the generic communication driver and the coupler device. The generic communication driver is configured to exchange data with device drivers integrated in the device access software and to transmit data received from the device drivers to the coupler device, and to forward data received from the coupler device to the respective device driver. The coupler device is configured to convert data traffic from a first format to a second format and from the second format to the first format.
