40、f preparing standards for data exchange for the purposes of meter reading, tariff and load control, and consumer information using various alternative communication media, with reference to IS0 and ITU standards. Meter data exchange can be local or remote. This part of IEC 62056 is restricted to loc
41、al data exchange, whereas remote data exchange is covered by other standards of the IEC 62056 series. O 17 July 2002 Page 7 EN 62056-212002 ELECTRICITY METERING - DATA EXCHANGE FOR METER READING, TARIFF AND LOAD CONTROL - Part 21: Direct local data exchange 1 Scope This part of IEC 62056 describes h
42、ardware and protocol specifications for local meter data exchange. In such systems, a hand-held unit (HHU) or a unit with equivalent functions is connected to a tariff device or a group of devices. The connection can be permanent or disconnectable using an optical or electrical coupling. An electric
43、al interface is proposed for use with a permanent connection, or when more than one tariff device needs to be read at one site. The optical coupler should be easily disconnectable to enable data collection via an HHU. The protocol permits reading and programming of tariff devices. It is designed to
44、be particularly suitable for the environment of electricity metering, especially as regards electrical isolation and data security. While the protocol is well-defined, its use and application are left to the user. This standard is based on the reference model for communication in open systems. It is
45、 enhanced by further elements such as an optical interface, protocol controlled baud rate switchover, data transmission without acknowledgement of receipt. The protocol offers several modes for implementation in the tariff device. The HHU or equivalent unit acts as a master while the tariff device a
46、cts as a slave in protocol modes A to D. In protocol mode E, the HHU acts as a client and the tariff device acts as a server. As several systems are in practical use already, particular care was taken to maintain compatibility with existing systems and/or system components and their relevant protoco
