A system 110 for transferring a sequence of actions to an electronic meter 114 through a bandwidth limited communications channel. The sequence of actions is programmed as a program file that is broken into pieces for transmission to the electronic meter 114. The pieces are received by the electronic meter, verified not to contain errors, and combined into a single program session. Any errors in the transmission are noted in a status table and the program file is retransmitted. Upon receipt of an execute command, the program session is commenced. After the session has completed the status table is updated. Thus, the electronic meter 114 may be programmed in a programming session that contains more data than can be transferred via the bandwidth limited communications channel. r---- ----------------------------- 1 14b 114b 114b 114b 114b rMeter Meter Meter114a Meter 114 Meter 0 1114a Meter Meter 114b 116 Collector Meter Data Collection r ------- - --- ------- Server 206 16 14b 206 Collector Meter 114a 0 114a Meter Meter Meter 114a 11Ab 0 114b b 0 M1.t 4bMeter Mt 114b Mtr0 0 Meter Meter 14 Meter Meter 14 |
