EDS
files and commissioning
The electronic data sheet (EDS) library is a collection of EDS files that can be registered with
RSNetWorx for Allen Bradley PLC’s and Compbus/D configurator for Omron PLC’s.
The EDS files, which are provided by Norgren and other manufacturers, contain configuration
and identification information for the devices. RSNetWorx for DeviceNet software can access
only those devices that have been registered. You must use the EDS Wizard within RS Networx
for registering EDS files for unknown devices, or if you have updated EDS files to install. To
install a new EDS file to your PLC please refer to the PLC manufacturers instruction manual or
online help.
Although you receive a large number of electronic data sheet (EDS) files with the configuration
software for DeviceNet, there may be a time when you need to acquire other manufactures EDS
files from the ODVA www.odva.org (Open DeviceNet Vendor’s Association) web site.
DeviceNet node commissioning tool (RS Networx Only)
The DeviceNet node commissioning tool lets you commission, that is, set the node address and
the baud rate parameters of, devices that are either connected to a DeviceNet network, or via a
point-to-point connection.
Before you can add any node to a live DeviceNet network, it must be commissioned. This
means that a node address and a baud rate must be programmed into the device. All Norgren
VS18/VS26 nodes are preset with a node address, which is usually set to 63, unless otherwise
stated by the user in the valve island configuration. These preset values will need to be
changed to meet your application needs. Once a device has been commissioned and attached
to a network, you can use the RSNetWorx for DeviceNet node commissioning tool to edit the
node address that was set previously. Some devices do not permit software setting of the node
address or baud rate. Refer to the device documentation for specific information.
Tip
For example, if two of the devices on your network are a photoelectric sensor and a hand
controller and you accidentally change the node address of the hand controller to be the same
as that of the photoelectric sensor, then the hand controller will no longer have a unique
address. This means that it will not be able to communicate on the network. If you cannot
access a device because you have used its node address for another device, you will have to
remove it from the network, re-commission it and then reinstall it on the network.
