Create-Configure Remote I-O Module

You use a Remote I/O (RIO) module entry in the
Controller Organizer I/O Configuration
module tree to establish the location of a RIO block transfer module. RIO module entries cannot be created while attached to the processor.
block-transfer
To move a block (64 words maximum) of data to or from an I/O module in one scan.
To create a remote I/O module
  1. Select the desired RIO Rack entry in the
    Controller Organizer I/O Configuration
     module tree.
  2. From the
    File
    menu, choose
    New Component/Module
    .
  3. Choose "RIO-MODULE Generic Remote I/O Module" from the
    Select Module
    dialog module type list.
  4. Select
    OK
    .
  5. Enter a name.
    name
    A title with 40 characters. It must start with a letter or underscore ("_"), however, all other characters can be letters, numbers, or underscores. Names cannot contain two contiguous underscore characters and cannot end in an underscore.
    TIP:
    The naming conventions are based on the IEC-1131 rules for identifiers.
    The name must be unique among all modules in the module tree.
  6. Enter a description for the new module, if desired.
    description
    A representation that can be a maximum of 128 bytes in length. You can use any printable character; carriage returns, tabs, and spaces are also supported. Standard ASCII characters consume 1 byte per character, allowing for 128 characters. Note that some characters (for instance, those used for Asian languages) take up to three bytes to represent one character, resulting in less than 128 characters maximum.
  7. Enter the I/O Group of the target module.
    I/O group
    A group of input and/or output circuits corresponding to a word in the input and output image tables.
    The number entered must be within the range indicated by the parent rack size and starting group. (For example, if the parent rack is sized as a half rack (4 I/O Groups) with starting group 2, the I/O Group is one of 2, 3, 4 or 5.)
  8. Enter the slot in the group for the target module.
    For most cases, this value should be zero. For 1771, 1747 and other adapters that support and are configured for 2-slot addressing mode, enter zero if the target is in the left slot of the I/O Group, and 1 if the target is in the right slot of the I/O Group.
    2-slot addressing
    A mode of addressing I/O in which each even/odd pair of I/O module slots of an I/O chassis is addressed as an I/O group. Each I/O module slot contains ½ of an I/O group.
  9. Select
    Finish
    .
    The module is now available to be used with block transfer reads and writes.
    No tags are created for RIO modules. Tags for data transfers must be created by the user and associated with the corresponding MSG instructions.
    tag
    A named area of the process-connected device or controller’s memory where data is stored. It is the basic mechanism for allocating memory, referencing data from logic, and monitoring data.
