Device Definition

Device Definition Overview

Use Overview view in the Device Definition dialog to define a device or change the device definition.

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 includes these parameters:

Define Counter – Parameters
Parameter	Definition	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)

Use Define Counter to define the counter parameters when the Encoder Type is configured as HSC and Connection is configured as Listen Only Data.

Define Counter (Listen Only) includes these parameters:

Define Counter (Listen Only) – Parameters
Parameter	Definition	Available Choices
Input00 is used for Reset, Store, Load, or Hold	Determines whether to use Input00 to trigger counter functions.	Cleared – Do not use Input00 for Reset, Store, Load, or Hold Selected – Use Input00 for Reset, Store, Load, or Hold

Define SSI

Use Define SSI to define the SSI parameters when the Encoder Type is configured as SSI.

Define SSI includes these parameters:

Define SSI – Parameters
Parameter	Definition	Available Choices
Enable Store via Input00	Defines whether the Store function is triggered using Input00.	Cleared – Store function is not triggered using Input00. Selected – Store function is triggered using Input00.
Invert Input00	Defines whether to invert the indicated input.	Cleared – A rising edge on Input00 triggers the Store function. Selected – A falling edge on Input00 triggers the Store function.

Define SSI (Listen Only)

Use Define Counter to define the SSI parameters when the Encoder Type is configured as SSI and Connection is configured as Listen Only Data.

Define SSI (Listen Only) includes these parameters:

Define SSI (Listen Only) – Parameters
