Device Definition

This section shows definitions for specifc configurations chosen in the Device Definition dialog.
To change the definition of a device, select Device definition in the Overview view.

Device Definition Overview

Use Overview view in the Device Definition dialog to define a device or change the device definition.
Device Definition Overview Example
Overview includes these parameters:
Overview Parameters
Parameter
Definition
Available Choices
Device Type
Displays the device catalog number and type.
Device-specific
Name
Enter an IEC 61131 compliant device name.
If an invalid character is entered in this field, or if the name exceeds 40 characters, the software ignores the character.
All valid values
Description
Enter the description of the device.
All valid values
Slot
Specify the slot number where the device resides. Only slots between 1 and the maximum number of I/O devices are valid depending on the platform.
When the device is created, the slot number defaults to the first available slot position.
When the controller is changed to one supporting a smaller maximum I/O count, the current slot value may no longer be valid.
1…32
Series
Specifies the series of the device.
Device-specific
Revision
Specifies the major and minor revisions of the device. The valid range for minor revision is from 1…255.
Device-specific
Electronic Keying
Defines the electronic keying used for the device. Electronic keying compares the device defined in the project to the installed device. If keying fails, a fault occurs.
ATTENTION:
Be 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.
For detailed information on Electronic keying, see Electronic Keying in Logix 5000 Control Systems Application Technique, publication LOGIX-AT001.
  • Exact Match
  • Compatible Module
  • Disable Keying
Connection
Specify the type of data transferred between the device and controller.
For the Listen Only choice, the controller and device establish communication without the controller sending any configuration or output data to the device. A full input data connection is established but depends on the connection between the owner-controller and the device.
  • Data
  • Listen Only Data
Encoder Type
Specify the type of encoder in which the module operates.
  • HSC
  • SSI

Define Counter

Use Define Counter to define the counter parameters when the Encoder Type is configured as HSC.
Define Counter Example
Define Counter includes these parameters:

Available Choices
Mode
Defines the mode in which the counter operates.
  • Count/External Direction
  • Count/Internal Direction
  • Up/Down Pulses
  • Quadrature X1
  • Quadrature X2
  • Quadrature X4
Invert Input A
Determines whether to invert Input A.
This parameter is only available when the counter mode is configured as Count/External Direction, Count/Internal Direction, or Up/Down Pulses.
  • Cleared – Do not invert the input.
  • Selected – Invert the input.
Invert Input B
Determines whether to invert Input B.
This parameter is only available when the counter mode is configured as Count/External Direction, Count/Internal Direction, or Up/Down Pulses.
  • Cleared – Do not invert the input.
  • Selected – Invert the input.
Invert Input A, B
Determines whether to invert Input AB.
This parameter is only available when the counter mode is configured as Quadrature X1, Quadrature X2, or Quadrature X4.
  • Cleared – Do not invert the input.
  • Selected – Invert the input.
Input Z Function
Defines the function for Input Z.
Each counter function (Reset, Store, Load, Hold) can only be triggered by one input.
For example, if you select the Input Z Function as "Reset, Hold", then the options that contain "Reset" and "Hold" are not available to select for the Input00 Function.
If you select any option for Input Z Function, then Input00 Function is automatically set to Not Used.
  • Not Used
  • Hold
  • Load
  • Load, Hold
  • Reset
  • Reset, Hold
  • Store
  • Store, Hold
  • Store, Load
  • Store, Load, Hold
  • Store, Reset
  • Store, Reset, Hold
Invert Input Z
Determines whether to invert Input Z.
  • Cleared – A rising edge on Input Z triggers the counter functions.
  • Selected – A falling edge on Input Z triggers the counter functions.
Input00 Function
Defines the function for Input00.
Each counter function (Reset, Store, Load, Hold) can only be triggered by one input.
For example, if you select the Input Z Function as "Reset, Hold", then the options that contain "Reset" and "Hold" are not available to select for the Input00 Function.
If you select any option for Input Z Function, then Input00 Function is automatically set to Not Used.
  • Not Used
  • Hold
  • Load
  • Load, Hold
  • Reset
  • Reset, Hold
  • Store
  • Store, Hold
  • Store, Load
  • Store, Load, Hold
  • Store, Reset
  • Store, Reset, Hold
Invert Input00
Determines whether to invert Input00.
  • Cleared – A rising edge on Input00 triggers the counter functions.
  • Selected – A falling edge on Input00 triggers the counter functions.

Define Counter (Listen Only)
