Device Definition

To change the definition of a device, select Device definition in the Overview view.
Device Definition Example
Device Definition includes these parameters:
Device Definition 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.
  • Exact Match
  • Compatible Module
Configured By
Determines which tags are generated when configuration is complete.
For the External Means choice, the controller and module establish communication without the controller sending any configuration or output data to the module.
  • External Means
  • This Controller
Input Data
Select the input data type for the device.
  • Safety Data
  • Safety Packed Data
Output Data
Select the output data type for the device.
  • None – If Configured By is set to External Means
  • Safety Data – If Configured By is set to This Controller
  • Safety Packed Data – If Input Data is set to Safety Packed Data

Safety Network Number

The Studio 5000 Logix Designer application automatically assigns a Safety Network Number (SNN) to safety modules as they are added to the project.
The SNN is a time-based number that uniquely identifies subnets across all networks in the safety system. All safety modules in a same system use the same SNN and are automatically assigned the same SNN by default.
The Studio 5000 Logix Designer application assigns an SNN to the first safety module that is added to a remote system. The application assigns the same SNN to additional safety modules that are added to this remote I/O system.
For more information on Safety Network Numbers, see the GuardLogix 5580 and Compact GuardLogix 5380 Controllers Safety Reference Manual, publication 1756-RM012.
To change the SNN of a device, select the ellipses next to the SNN field in the General view.
