Abstract
An industrial controller includes a processing unit and a memory. The industrial controller is operable to communicate using an optimized connection packet including I/O data from a plurality of I/O modules arranged as an unstructured data block. The processing unit is operable to operate on the I/O data within the optimized connection packet to control a process. The memory is operable to store a plurality of cast tags. Each cast tag is associated with one of the I/O modules and provides a logical reference to a subset of the unformatted data block including at least a portion of the I/O data for the associated I/O module.
Claims28
An industrial control system, comprising:
- a plurality of I/O modules operable to interface with a process to exchange I/O data with the process;
- a scanner operable to exchange the I/O data with the I/O modules and communicate using an optimized connection packet including the I/O data for each module arranged in an unformatted data block;
- and
- an industrial controller operable to exchange the optimized connection packet with the scanner and control the process using the I/O data included in optimized connection packet, the industrial controller being further operable to store a plurality of cast tags, each cast tag being associated with one of the I/O modules and providing a logical reference to a subset of the unformatted data block including at least a portion of the I/O data for the associated I/O module.

A method for referencing industrial control data, comprising:
- exchanging I/O data with a plurality of I/O modules;
- generating an optimized connection packet including the I/O data for each module arranged in an unformatted data block;
- defining a plurality of cast tags, each cast tag being associated with one of the I/O modules and providing a logical reference to a subset of the unformatted data block including at least a portion of the I/O data for the associated I/O module.
