Interface Module Installation & Reference
Although an Allen-Bradley PLC and RSNetworx for DeviceNet were chosen to illustrate steps in this
manual, the DeviceNet Interface Module is not limited to this configuration. Other PLC and control
software packages can be used to achieve the same communication. If you are using different PLC or
control software, the instructions provided here are generally applicable.
NOTE
: All of the instructions provided in this manual are exclusive to the DeviceNet Interface Module
sold and supported by Cognex.
Connecting the Interface Module to a DeviceNet Network
This section describes how to connect the Cognex DeviceNet Interface Module to a DeviceNet network,
and how to use RSNetworx to configure DeviceNet communications for an In-Sight vision sensor.
Step 1 – Connect the Interface Module to the Network
Attaching the Interface Module to the DeviceNet network:
1. Following Rockwell’s RSNetworx device installation procedure, install the EDS file contained on
the DeviceNet Interface Module diskette supplied, using the EDS Wizard.
2. On the Interface Module, set the two rotary MACID switches to the unused MACID you want to
assign to the module. Similarly, set the BAUD RATE switch to your DeviceNet baud rate.
3. Attach a DeviceNet drop cable to the Interface’s 5-pin male micro connector.
4. Set up DeviceNet to communicate with the Interface:
a) Use Browse or Online in RSNetworx to locate the Interface Module on the network.
b) Confirm that RSNetworx has assigned the Interface Module the correct node number and
type, given by the EDS file that you registered in step 1.
The next step is to configure and assign the Interface Module to a Master Device, typically the PLC/SLC’s
Scanner module.
Step 2 – Configure the Interface
To configure the Interface Module in RSNetworx, go Online and double-click on its graphical
representation; a dialog will open. Select the
Parameters
tab (see Figure 1) in the property sheet of the
dialog and upload the parameters from the module.
NOTE
: If the settings are not already at the default settings, call the default settings and download them
to the module before configuring individual parameters.
