The Problems
1. Too many devices to manage properly, approximately 10,000 devices in the field.
2. Access to device event data was non-existent or difficult due to terrain issues.
3. Without event data, root-cause analysis of circuit reliably was impossible.
4. Safety concerns.
5. Multi-vendor devices

The Project – Agile Development
Instead of delivering one major update to the software, the features were staged and delivered to the utility in an incremental fashion. Benefits: 1. Utility was able to evaluate
functionality early. 2. There was transparency in
project progress.

The Project – Driving Innovation
• The customer was involved in the definition of new features and capabilities of IED Management System.
• These are win-win scenarios:
1. The customer receives the product they are looking for.
2. Integration company increases the functions and capabilities of its software that other users can take advantage of.

The Project – Driving Innovation
1. Application Driver 2. Device State 3. Device Communication Status 4. Manually Triggered Functions
– Communications Status Check – Get Data – Get Configuration – Get SOE – Get Fault Files – Jobs – Sequence of Events – Publishing Configurations

Application Driver
• Identified a relay to be a closed system. The protocols are proprietary, forcing users who want to manage their devices to use their software.
• In an analysis of the protocol, it was evident that parts of the messages were encrypted and/or hashed.

Application Driver (cont’d)
• Controlling the end device was done through the vendor application instead of directly to the device through the communication protocol. This is called an Application Driver in the IED Management System.
