    • In a method for operating a field device of automation technology capable of special-functionalities, an enabling code set having a plurality of enabling code is managed in a superordinated, key-management unit. With the assistance of the enabling codes, special-functionalities can be enabled in field devices. Associated with individual enabling codes of the enabling code set is, in each case, an attribute, “free” or “blocked”. If a special-functionality is needed, then an enabling code is transmitted to the field device, in case an enabling code with attribute “free” is present. Following transmission, the attribute of the transmitted enabling code is changed from free to blocked. The method permits enabling code to be used very flexably.
    • 在一种用于操作能够实现特殊功能的自动化技术的现场设备的方法中,具有多个使能代码的启用代码集在上级密钥管理单元中被管理。 在启用代码的帮助下,可以在现场设备中启用特殊功能。 在各种情况下,与启用代码集的单独启用代码相关联的属性为“自由”或“阻止”。 如果需要特殊功能,则启用代码将被传送到现场设备,以防存在具有“空闲”属性的启用代码。 传输后,所发送的使能码的属性从空闲状态改变为阻塞状态。 该方法允许非常灵活地使用代码。
