Input and Output The application of the INTERBUS bit packing rules to the sample island assembly

Data Exchange results in four words of output data and five words of input data. The tables that follow show how digital data is bit packed for optimization, and how data, status, and echo output data (from outputs) appear in the PLC as the same data type (digital input data). In these tables, N refers to the island node number. That is, N1 represents the first addressable node (module) on the sample island bus, N2 the second, and so forth.
