The setup of the DNP protocol for a meter is a 4 step process:
Step 1. Navigate to ION Setup ‘Setup Assistant’ -> Communications -> 3rd Party Protocols and choose DNP 3.0 tab.
Select the Parameter Map and click "Edit"
- Step 3. Setup your point map and click "Finish".
- Step 4. Navigate to ION Setup ‘Setup Assitant’ -> Communications -> Serial Settings and modify protocol of the COM port of your choice to the DNP protocol.
Note 1: Ethernet does not require this step. it will be enabled by default after step 3.
Note 2: You can also accomplish step 4 by accessing your meter's Advanced ION Modules (hold the CTRL key on your keyboard and click on the meter in Network viewer mode)
Navigate to "DNP Slave Options Modules" and open your desired DNP Slave Options module.
Navigate to Setup registers and modify "DSOx CommPort" from "None" to COMx depending on what serial COM port you are using.
This should complete the DNP protocol setup.
