A method for the startup of a field device of process automation technology uses a service program which runs on a service unit connectable with the field device and with a field device manufacturer service computer SC via a public network (e.g. Internet). The service program communicates with the field device and reads-out its serial number and software version number. Then the service program communicates with the field device manufacturer service computer and ascertains the current software version number belonging to the serial number of the field device. If the two software version numbers do not agree, a corresponding report is produced and, as required, in a third method step, the current software version is downloaded from the service computer and transferred into the field device.
