Product Description:

The Remote I/O communications module allows a SCANport product to look and act like a Remote I/O chassis when connected to a programmable controller. Data contained in the input/output image table is transferred between the programmable controller by the Remote I/O scanner, the same as with any Remote I/O chassis. You control the location of data transferred by setting the rack address and
starting group. You control the amount of data by setting the DIP switches on SW3. Important: Thecommunications module does not scale the data that is transferred. Consequently, all scaling of the data must be done in the controller. Refer to the user manual for your SCANport product for details on
device units. Important: The Remote I/O to SCANport conversion is asynchronous. Data sent to the adapter for transfer to the drive must be maintained until the drive has received data.DIP switches on SW3 determine how the data contained in the programmable controller I/O image table is used in the drive. Figure shows an I/O image table.

Product's Character:

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.
