Device Definition

Use the settings on the Device Definition dialog to:
  • Define the device revision.
  • Select the electronic keying.
  • Configure the connections to the device.
Device Defintion parameters
Parameter
Description
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.
Description
Enter the description of the device.
The description must be within 128 characters. If the description exceeds the maximum length, the software ignores any extra characters.
Ethernet Address
Enter the IP address of the device
Revision
Set Major Revision to 2 if the connection with the current FLOWave Revision should be established. FLOWave manufacture dates 06/2025 or later default to Revision 2.
Set Major Revision to 1 if you want to connect with Revision 1 FLOWave. This is necessary for devices older than the manufacture date of 06/2025 or newer devices with Compatibility Mode set to Revision 1.
Set Minor Revision to 1.
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.
Valid values include:
  • Exact Match
  • Compatible Module
  • Disable Keying
See the Electronic Keying section below for more details.
Configuration
Enter "Yes" if device-specific data configured in "CONFIGURATION" menu should be downloaded to the device during connection establishment.
Enter "No" if no configuration device-specific data should be downloaded to the device during connection establishment.
Process Packages
Enter the Package, which is compatible with the FLOWave. If the incorrect Package is selected, it is possible that invalid or insufficient data will be displayed.
For example, the Standard Measurement Package does not include data for Density, Mass, or Concentration measurement. If your FLOWave has one of these functions, please select the corresponding Package.
The following Packages and their associated cyclic data are available:
Standard:
  • Volume flow
  • Temperature
  • Liquid velocity
  • Volume totalizer 1
  • Volume totalizer 2
  • Differentiation factor
  • Acoustic transmission factor
  • Device state namur
Density & Mass Flow:
  • Mass flow
  • Density
  • Mass totalizer 1
  • Mass totalizer 2
Concentration:
  • Concentration 1
  • Concentration 2

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.
Attributes compared by Electonic Keying
Attribute
Description
Vendor
The device manufacturer.
Device Type
The general type of the device, for example, digital I/O device.
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.
Electronic Keying options
Keying Option
Description
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. Typically, use Compatible Module to replace a device with another device that has these characteristics:
  • Same catalog number
  • Same or higher major revision
  • Minor revision:
  • 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.
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.
CAUTION:
Use extreme caution when using Disable Keying. If used incorrectly, this option can lead to personal injury or death, property damage, or economic loss.
We strongly recommend not using Disable Keying.
If using Disable Keying, take full responsibility for understanding whether the device being used can fulfill the functional requirements of the application.
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.
Carefully consider the implications of each keying option when selecting one.
IMPORTANT:
  • Changing Electronic keying parameters online interrupts connections to the device and any devices that are connected through the device. Connections from other controllers can also be broken.
  • A loss of data may occur if an I/O connection to a device is interrupted.
