Item 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. The Input IO Data Length status word of RTU-DNET occupies 2 bytes. One input N/A channel of the special module occupies 2 bytes.
DeviceNet Network Scanner DVPDNET-SL Item Function Default The digital output points shall be 8’s multiple. The number will DIDO Output Points (Y) be regarded as 8 when it is less than 8 and regarded as 16 N/A when it is bigger than 8 but less than 16. AIAO Module Number The number of special modules connected to RTU-DNET. Diagnostic Intervel Time The interval when RTU-DNET executes diagnosis.
DeviceNet Network Scanner DVPDNET-SL (16) Confirm the parameters and I/O data in VFD-B and click on “OK”. 2. Configuration of DVPDNET-SL (1) Double click on DNET Scanner (node 01), and the “Scan Module Configuration..." dialog box will appear. You can find the currently available nodes, RTU-DNET and VFD-B Drives 230V 3HP, in the list on the left side. On the right side, there is an empty “Scan List”.
DeviceNet Network Scanner DVPDNET-SL (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.

DeviceNet Network Scanner DVPDNET-SL (4) Program explanations: In the beginning of the program, clear the response message editing area and request message editing area to 0. When M0 = On, DVPDNET-SL will send out request message, reading Class 1>>Instance 1>> Attribute 1 of the target equipment (node address: 02). If the communication of explicit message is successful, the slave will return with a response message. When M0 = On, DVPDNET-SL will only send out request message once.
