Why I Cannot Connect Through ETH2 But Can Through ETH1 on SCADAPack 474i and 470i.

In the SCADAPack 474i and 470i devices, Ethernet ports ETH1 and ETH2 serve different roles in the RTU system. One challenge that may arise is a difficulty connecting through ETH2 while ETH1 works fine.

Understanding the Ethernet Port Roles

• ETH1 is a standard Ethernet interface used for direct communication with the RTU.
• ETH2 and ETH3 are internally linked by a switch inside the SCADAPack. This internal connection is used to synchronize data between the RTU and the Edge platform.

This internal switch facilitates data synchronization between the RTU and the Edge board. As a result, ETH2 relies on the Edge platform to process data.

Requirements for Accessing ETH2

To successfully connect through ETH2, the following conditions must be met:

1. Edge Board Password Must Be Set
   Access to ETH2 is gated by authentication. You must configure the Edge board password to enable communication.

2. Firmware Versions Must Be Compatible
   The RTU firmware and the Edge firmware must be synchronized — meaning they should be compatible and ideally from corresponding version sets.

Where to Find Configuration Instructions

For detailed steps on setting the Edge password and updating firmware on SCADAPack 47xi models, refer to the Help manuals included with RemoteConnect.
