About us
Overview
When a generic device is added to an EtherNet/IP network, the Control Expert EtherNet/IP configuration tool automatically opens its properties window for immediate configuration. When operating offline, the properties window consists of the following 5 pages. Only the first two of these pages need to be configured:
In this page...
Do the following...
General
Enter configuration settings, as described below.
Connections
Enter configuration settings, as described below.

Configuring the General Page
To configure the General page:
Step
Action
1
Click on the General page:
2
In the General page, edit the following settings:
Device Name
The label for the remote device in the EtherNet/IP device list. Either:
  • type in a unique name using letters, numbers and the underscore character (_), or
  • accept the auto-generated name (DEVICE_N}
Number
The relative position in the EtherNet/IP device list. Either:
  • accept the default (i.e. the next available number), or
  • select a different number from the drop-down list
Link Parameters
Select this setting to:
  • lock the IP Address setting, and
  • set the last octet of the IP Address equal to the value selected in the Number parameter
De-select this setting to unlock the IP Address setting.
Active Configuration
Select this setting to include this remote device in EtherNet/IP network communications.
De-select this setting to exclude this device from network communications, but save the device’s configuration settings.
IP Address
The IP Address of this remote device. This setting is:
  • editable, when the Link Parameters field is de-selected
  • locked, when the Link Parameters field is selected
By default:
  • the first 3 octet values equal the first 3 octet values of the EtherNet/IP module’s IP address
  • when the Link Parameters field is selected, the last octet value equals the value selected in the Number parameter
Enable DHCP
TRUE activates the DHCP client in this remote device. On startup, this device requests its IP address from a DHCP server.
Note: the EtherNet/IP module can be configured to act as a DHCP server.
DHCP Client Identifier
If the DHCP client is enabled, select the identifier the DHCP server will use to recognize this remote device:
  • MAC Address
  • Device Name
Mac Address/Device Name
Type in the value of the DHCP client identifier.
Note: The Device Name referenced here is not the same as the Device Name described in the first row of this table.
Configuring the Connections Page
To configure the Connections page:
Step
Action

In the Configured Connections list, click on General to display the general connection settings in the Connection Parameters list, shown below:
3
In the Connections page, edit the following general connection settings:
Connection Health Bit Offset
(read-only)
Request Packet Interval (RPI)
The refresh period for this I/O connection.
Value range: 2...65535 ms
Default = 30 ms
Time-out Multiplier
The value, multiplied against the RPI rate, which triggers an inactivity timeout.
Value list: 4, 8, 16, 32, 64, 128, 256, 512
Default: 4
Input Size (in bytes)
The number of bytes reserved for input data, in bytes.
Value range: 1...509
Default: 1
Input Instance
The instance identifier for inputs: 101.
Output Size (in bytes)
The number of bytes reserved for output data, in bytes.
Value range: 1...505
Default: 1
Output Instance
The instance identifier for outputs: 102.
Configuration Instance
The instance identifier for configuration data: 103.
Note: The Input Size and Output Size parameter settings are determined by the size—in bytes—of the input data and output data sections of your specific application.

Click OK to save your settings and close the Properties window.
The next step is to configure I/O settings. For an example of I/O configuration for a generic remote device, see how the following I/O items were configured:
