The ANSI C12.19 standard defines a table structure to pass utility application data between a meter and a computer. The purpose of these tables is to define structures for data transport to and from meters. The Read Table Tag performs a data reading from a table, which can already be cached or can be transferred from a meter immediately when executing. Depending on the type of table, the execution of data transfer behaves in different ways. Ordinary tables perform data transfers synchronously, but vector tables require an execution of the Start Read Tag so that a data transfer previous to execution occurs and then data can be read.
