A method for providing static data and dynamic data of a service/display menu for a mobile device from a field device of process automation, wherein the field device contains identification data, especially field device type and firmware version, and, associated therewith, a total amount of static data and dynamic data, the method comprising the steps of:
- upon query of the mobile device, dynamic data and/or static data are transmitted with a data transmission rate from the field device to the mobile device via a wireless interface, especially via Bluetooth or WLAN, especially according to a standard of the IEEE 802.11 family;
- static data required for application, especially for representation, and/or changing of transmitted dynamic data are transmitted from the field device to the mobile device, when the static data corresponding to the identification data are not already present in the mobile device, wherein these static data make up only a portion of the total amount of static data in the field device;
- and
- an application, especially a representation, and/or changing of the transmitted dynamic data by the mobile device is enabled with the portion of the static data, wherein these static data are stored in a memory in the mobile device.
