Abstract

A method for transferring data blocks from a field device to a server, each data block including data describing an operation of the field device during a block time period is provided. The method includes setting a first and a second pointer delimiting a completed time period; and, until a predetermined transfer period elapses: transferring the data blocks having a block time period that is later than the second pointer to the server in a chronological order; and if all data blocks having a block time period that is later than the second pointer have been transferred to the server, transferring the data blocks having a block time period that is earlier than the first pointer to the server in an anti-chronological order. Data blocks can efficiently and reliably be transferred to the server.

Claims12

Dependent claims

A method for transferring data blocks from a field device to a server device, each data block comprising historical data describing an operation of the field device during a block time period, the method comprising:

setting a first pointer and a second pointer delimiting a completed time period such that all data blocks having a block time period comprised within the completed time period have previously successfully been transferred from the field device to the server device;
and
until a predetermined transfer period elapses:
transferring the data blocks having a block time period that is later than the second pointer to the server device in a chronological order starting from the data block having a block time period that is closest to the second pointer;
and
if all data blocks having a block time period that is later than the second pointer have been transferred to the server device, transferring the data blocks having a block time period that is earlier than the first pointer to the server device in an anti-chronological order starting from the data block having a block time period that is closest to the first pointer.
