(10) Click on “Scan IO”, and the “Warning” dialog box will appear. (11) Click on “OK”. DeviceNetBuilder will then detect the special module connected to RTU-DNET and the number of points in the Slim DI/DO extension unit and display the information on “RTU Configuration” page.
DeviceNet Remote I/O Communication Module RTU-DNET (12) Double click on RTU-DNET icon, and you will then see “RTU Setup” dialog box. (13) Set up the parameters in RTU-DNET and confirm its I/O information. Item Input IO Data Length Output IO Data Length DIDO Input Points (X) DIDO Output Points (Y) AIAO Module Number Diagnostic Intervel Time IO Module Offine Treatment 26 Function Default The sum of the length of the status word of RTU-DNET and the input data of the special module connected to it.
DeviceNet Remote I/O Communication Module RTU-DNET Item Function IO Module Error Treatment How RTU-DNET will react when it detects errors. You can choose “Ignored”, “Alarm” or “Stop DeviceNet IO”. For you to decide whether to add control word and status word to I/O data. When you choose not to do it, the I/O data Add control word in RTU-DNET and DeviceNet master will not include control and status word to word and status word.
DeviceNet Remote I/O Communication Module RTU-DNET (3) Confirm all the settings and click on “OK”. Next, download the configuration to DVPDNET-SL. If DVP-SV is in RUN mode while you are downloading the configuration, a "Warning” dialog box will appear. (4) Click on “OK” to continue the download. Make sure DVP-SV is in RUN mode. Now, you can see the MS LED and NS LED on RTU-DNET become green. 3. Follow the steps given above to configure DeviceNet network.
