Device Definition

To change the definition of a device, select Device definition in the Overview view.
Device Definition dialog has following views to define your device and configure the channel operating mode:
  • Overview View
  • Channel Assignments View

Device Definition - Overview View

The Device Definition - Overview View appears first when you create a module. Use this view to define the module.
If you have already created the module and want to modify these parameters, go to Overview → Device definition, then select Overview tab.
IMPORTANT: When controller status is online, you can only change the parameters Name, Revision (only minor revision), and Electronic keying from this view.
Device Definition - Overview View Example
Overview view includes these parameters:
Device Definition - Overview View 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.
For detailed information on Electronic keying, see Electronic Keying in Logix 5000 Control Systems Application Technique, publication LOGIX-AT001
