Create-Configure Module 1734-ACNR 1738-ACNR

Use this tab to create/view module properties for 1734-ACNR and 1738-ACNR ControlNet adapters. To use these modules as adapters, the parent module must be a CNB bridge.
The first three parameters on this tab are read-only. These parameters provide:
  • Type and description of the module being created.
  • Vendor of the module being created.
  • Name of the parent module (typically a 1756-CNB module or a 1788-CNC module).
To create an adapter
  1. In
    Name
    , enter the name for this adapter.
    Use an IEC 61131-3 compliant name. This field is required. If incomplete an error message appears when you exit this tab. An error message also appears if a duplicate name is detected, or an invalid character is entered. If the maximum allowable name length is exceeded, the software ignores the extra character(s).
    IEC-61131 Name Standard
    (The names are composed per IEC-61131, section 2.1.2.)
    An identifier is a string of letters, digits, and underline characters that begin with a letter or underline character. Underlines are significant in identifiers (for example, A_BCD is interpreted differently than AB_CD). Multiple leading or multiple (consecutive) embedded underlines are not allowed, trailing underlines are not allowed, and letter case is not considered significant.
    TIP:
    In
    Logix Designer
    , most component names are limited in length to 40 characters or less.
  2. In
    Description
    , enter a description for the adapter (optional), up to 128 characters.
    Use any printable character in this field. If the maximum length is exceeded, the software ignores any extra character(s).
  3. From the
    Comm Format
    list, choose the communication formats: non-I/O modules used between the adapter and the controller.
    Choose from:
    • Rack Optimization (default)
    • Listen Only - Rack Optimization
    • None
      When choosing a communication format, the configuration formats for the module is also defined.
      TIP:
      Cannot change the communication format once created. To change configuration, delete and recreate the module.
  4. In
    Node
    , enter the node number in which the adapter resides.
    The Node value is constrained by the available nodes on the ControlNet network (between 1 and 99).
    TIP:
    The Node number is used in the Current Path when establishing a connection to the module. When selecting a node already in use, an error message is appears when clicking Apply or OK.
  5. In
    Chassis Size
    , enter the size of the chassis in which the adapter resides.
  6. Note the Slot number for the module.
    For 1734-ACNR and 1738-ACNR modules, the Slot number field is set to 0, and this field is read-only.
  7. From the Electronic Keying list, choose
    Electronic Keying
    Electronic Keying reduces the possibility of using the wrong device in a control system. Electronic Keying compares the device defined in the project to the installed device. If keying fails, a fault occurs.
    These attributes are compared:
    Attribute
    Description
    Vendor
    The device manufacturer.
    Device Type
    The general type of the device, for example, digital I/O module.
    Product Code
    The specific type of device. The
    Product Code
     maps to a catalog number.
    Major Revision
    A number that represents the functional capabilities of a device.
    Minor Revision
    A number that represents behavior changes in the device.
    Compatible Module,
    Compatible Module
    • Compatible Module lets the installed device accept the key of the device that is defined in the project when the installed device can emulate the defined device. With Compatible Module, typically replace a device with another device with these characteristics:
      • Same catalog number
      • Same or higher Major Revision
      • Minor Revision as follows:
        • If the Major Revision is the same, the Minor Revision must be the same or higher.
        • If the Major Revision is higher, the Minor Revision can be any number.
    Exact Match, or
    Exact Match
    Exact Match indicates that all keying attributes must match to establish communication. If any attribute does not match precisely, communication with the device does not occur.
    Disable Keying.
    Disable Keying
    Disable Keying indicates that the keying attributes are not considered when attempting to communicate with a device. With Disable Keying, communication can occur with a device other than the type specified in the project.
    WARNING:
    Be extremely cautious when using Disable Keying; if used incorrectly, this option can lead to personal injury or death, property damage, or economic loss.
    We
    strongly recommend
     that you
    do not use
     Disable Keying.
    If you use Disable Keying, you must take full responsibility for understanding whether the device being used can fulfill the functional requirements of the application.
  8. View status information if you wish.
    status
    The condition of the circuit or system represented as logic 0 (Off) or logic 1 (On).
    This term is also used to describe module status as follows:
    This status:
    Indicates:
    Standby
    a transient state that occurs when shutting down
    Faulted
    the controller is unable to communicate with the module
    When the status is Faulted, the
    Connection
    tab displays the fault.
    Validating
    a transient state that occurs before connecting to the module
    Connecting
    a state that occurs while the connection(s) are being established to the module
    Running
    the module is communicating and everything is working as expected
    Shutting Down
    the connections are closing
    Inhibited
    the connection to the module is inhibited
    Waiting
    a connection to this module was not made for one of these reasons:
    • its parent did not make a connection to it
    • its parent is inhibited
    • its parent is faulted
    Offline
    not online
