Data transaction efficiency in batch control: Eliminating the middle man

This paper explores methods of moving data directly from the source to the final point of use, whether this is an operator console, a controller, or data archived on disk media, without passing through intermediate databases, applications, and other “middle men.”

By Scott W. Sommer, Automation Technology Manager, Jacobs Engineering Group

A new paradigm is emerging, one in which the “middle man” in batch data transactions is eliminated, thereby eliminating the potential errors and timing issues that occur as data pass through intermediate applications, gateways, and protocol conversions.

The Directed Data Transaction Model described in this paper is a methodology that yields a batch control network design which minimizes the number of data transactions in the system, while increasing reliability and data efficiency. This methodology is independent of the process type, instrument bus technology, control system hardware or software type, or communication protocol. With the wealth and diversity of data transaction, process control, batch control, and network hardware and software components on the market today, a solution to fit every application need can be found by applying the Directed Data Transaction Model.
