Does the 1769-SDN come with a warranty?
Yes, the 1769-SDN includes a free 2-year DO Supply warranty. You can upgrade to a 3-year warranty at checkout for even more protection.
How does the 1769-SDN module communicate to slave devices?
The 1769-SDN communicates with devices through poll, strobe, change of state, or cyclic I/O messages.
What does 1769-SDN Error Code 91 mean? What should I do?
The 1769-SDN Error Code 91 (Bus Off) indicates the Bus off condition has been detected on the integral DeviceNet port. If you see this error check the DeviceNet connections and the Baud Rate. You should also check the system for possible sources of network interferences, such as a failed slave device.
Where can I send the 1769-SDN to be repaired?
DO Supply, Inc. offers a variety of repair services for the 1769-SDN.
What is this module’s heat dissipation?
The 1769-SDN dissipates around 440 milliAmps of heat at a voltage of 5 VDC.
The 1769-SDN DeviceNet scanner module in a typical configuration acts as an interface between DeviceNet devices and the programmable controller. The 1769-SDN over the DeviceNet work communicating as a master will:
Read I/O to and from slave devices
Communicate to various other peer devices
Also upload and download to programs to select Micro Logix processors through the DeviceNet network
Additional parts used for testing
1769-L32E
1794-ADN
1794-TB3
1794-OA8
1784-U2DN
Note: RsNetworx for DeviceNet is required in this procedure, the 1784-U2DN is a USB communications device, this device is not required if you are able to talk to the DeviceNet work through other means.
Visually inspect the card for damaged components
Ensure the card is connected and locked in place using the locking/connecting tab on the top of the card.
Be sure the correct revision is configured in the program.
Error codes 98, 99 ,E2 ,E4 ,E5 will mean you will need a new 1769-SDN card check publication for specific details.
Be sure the same node address is not being used on multiple modules.
Check to see DeviceNet communications cable is terminated in all connectors. correctly, has 24v DC applied, correct length is being used and the correct resistors are being used in the right place.
Check scanlist to be sure that your configuration is downloaded into the scanner.
1769-SDN Testing
Power on all devices
Open RsNetworx for DeviceNet
Under the network tab select online then select the device network from the window.
All the Device Network modules should come up, double click the device, you will be communicating through, we select the 1794-ADN.
Once open select I/O summary and upload.
Now under module configuration we are given a list of compatible modules for the 1794-SDN, the 1794OA8 was automatically selected.
Download the configuration by clicking the download button.
Now open the configuration for the 1769-SDN scanner module
Go to Scanlist and upload, to move modules in and out of the scanlist us the button highlighted below, move the 1794-ADNinto the scanlist.
Note: To check I/O point check under the input and output tab
DeviceNet configuration is done
In RsLinx 5000 create a new program with the 1769-L32E
Add the 1769-ADN to the compactbus local, be sure to use the ADN module with the correct revision selected.
Download the program to the processor.
Go to controller tags, open the output tab for the ADN module, open the command registry, set command registry to 1.
Now open the “Local:1.O.Data” select Data[0], this will control the output for the 1794-OA8.
Changing the value from 0 to 255 and all the output will turn on.
