PROBLEM TO BE SOLVED: To provide a logical reference to a subset of unformatted data block (115, 120) including at least a portion of I/O data for an associated I/O module (30). SOLUTION: An industrial controller (15) includes a processing unit 16 and a memory (17). The industrial controller (15) is operable to communicate using an optimized connection packet (100) including I/O data from a plurality of I/O modules (30) arranged as the unstructured data block (115, 120). The processing unit (16) is operable to operate on the I/O data within the optimized connection packet 100 to control a process. The memory (17) is operable to store a plurality of cast tags (125). Each cast tag (125) is associated with one of the I/O modules (30). COPYRIGHT: (C)2007,JPO&INPIT
