Area | Microservice | Gaps Identified | Criticality | Why Important | Recommended Actions |
---|
Device | OPC UA | Missing | | New installations of SCADA systems are typically expected to be compliant with the OPC UA standard | Integrate Samsung DS for OPC UA |
Device | OPC DA | Missing | | Although OPC UA is an emerging standard, E&P Companies are still massively using OPC DA in legacy systems and in some cases in new installations as well | Assess resources to develop this |
Device | Modbus | Seems like the current Modbus implementation is querying 1 register at a time on the Modbus Slave. Modbus requests should be grouped together requisting multiple registers with a single call. | | Sending too many requests is invasive on the PLC which needs to conserve CPU cycles to perform its control duties | Engage Device WG and discuss with them how to handle this |
Device | Zigbee | Missing | | Wireless sensors are slowly gaining traction for non-critical measurements as wiring can be tough in certain constrained environments. Zigbee would be a good option. | Assess resources to develop this |
Device | LoRa | Missing | | Wireless sensors are slowly gaining traction for non-critical measurements as wiring can be tough in certain constrained environments. LoRa would be a good option. | Assess resources to develop this |
Device | GPS | Missing | | Could a GPS DS serve to get the coordinates (lat/long - 2 floating point metrics) from the gateway? | Assess resources to develop this |
Device | Profinet | Missing | | Siemens hardware is used in many Oil&Gas installations (e.g. North Sea) and Profinet I/O would be a suitable protocol for interfacing with EdgeX | Assess resources to develop this |
Device | DDS | Missing | | DDS is used in drilling for data messaging on critical items | Core | Data | Core | Metadata | Core | CommandAssess resources to develop this |

Support | Logging | Need to be able to specify persistency policies for type of logs | | Different logs are required for liability purposes and can be assessed in case of incidents | Engage Core WG and discuss with them how to handle this |
Export | Client Registration & Distribution | Missing mechanism for backfilling historical data. (perform an export job from start-timestamp to end-timestamp) | | Retrieve historical data back to the cloud | System | System Management | Connection loss handling: changes made while offline will be cached and sent when connection is re-establishedEngage Applications WG and discuss with them how to handle this |
Export | Client Registration & Distribution | Missing Osisoft PI Export Capabilities | |
| Vertical Solutions WG will develop this. Sync with Export WG. |
