To accomplish this: 1. Disable Polling Enable while you are making changes. All adjustable parameters that configure the DNI for operation are set up through this configuration utility. Page 74 Setup, Programming, and T roubleshootin g Because of the many variables and requirements associated with any particular installation, Rockwell Automation cannot assume responsibility or liability for the actual use based on the examples and diagrams.
If something happens and communications are lost cable is cut or removed, DNI loses power or faults, etc. The user can program the controller to respond to a loss of communications, if desired. If you prefer your application to have the controller maintain the outputs in their last state, remove this rung. Or, if you want additional logic to control your outputs, remove this rung and program the outputs as your application requirements warrant.
When communications are re-established, the outputs automatically recover. If it is desired that the outputs do not clear on a communications error, remove this rung from the program. This procedure is recommended because the latency issue associated with polling devices is minimized.
Polling is a mechanism that is used to acquire data from a device. If the input data has changed, bit B is set. Page 83 Application Examples The rung is used to reset a completed or errored message instruction. Resetting the MSG instruction will re-arm it to re-transmit.
Page 84 Application Examples Every device on DeviceNet either initiates or responds to some type of explicit message to either read get or write set data. The write message must have a data length of five words. I have modified the scanner configuration but the fault code continues. Can you help?
Thanks a lot:D. I would go online with a new configuration, delete the DNI from the scan list, then cycle power on the SDN, then go back on-online and download your backup. If this "DeviceNet. Change the Scanlist to 4 bytes Input and 4 bytes Output, and the Error 77 size mismatch should be resolved.
