Abstract
An improvement in an industrial controller having a processor with a memory holding an I/O table used for storing inputs and outputs transmitted between the industrial controller and a controlled process, via multiple I/O devices, uses templates associated with each I/O device to define the partitioning of the I/O table for the data. The templates define data types and ordering of data required for the particular I/O device permitting the space in the I/O table to be efficiently and intuitively allocated. The templates also relate physical addresses in the I/O table to program variables used by the control program.
