The name of the tag will reflect the name you assigned the earlier. The "C" sub-group contains the contents of the configuration assembly, which is not currently used in the 1203-CN1. The "O" subgroup contains one entry for each word of output data you configured, and the "I" sub-group contains one entry for each word of input data you configured. The "O" sub-group corresponds directly to output data for a PLC-5 described on page 5-2 of the 1203-CN1 user manual (i.e., for most common configurations, word 0 is the logic command, word 1 is the speed reference, words 2 and 3 are the first pair of data links, etc.). The "I" sub-group is similar to the input data for a PLC-5, except that it is shifted by two words (i.e., word 2 is the logic status, word 3 is the speed feedback, etc.). Words 0 and 1 of the "I" sub-group represent network status data sent by the 1203-CN1 but not processed directly by the ControlLogix processor. At this point, I/O between the ControlLogix processor and the 1203-CN1 should be configured and running, and the meaning of the various I/O words should be understood. If you need further assistance in configuring I/O, please contact technical support.
