Description

Scope of this activity is to perform a gap analysis on the current status of EdgeX microservices and deliver specific market requirements to other Working Groups.


Requirements

As part of the gap analysis, common requirements in Oil&Gas will be taken into account.


Design

AreaMicroserviceGaps IdentifiedCriticalityWhy ImportantRecommended Actions
DeviceOPC UAMissing

HIGH

New installations of SCADA systems are typically expected to be compliant with the OPC UA standardIntegrate Samsung DS for OPC UA
DeviceOPC DAMissing

HIGH

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 wellAssess resources to develop this
DeviceModbusSeems 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.

HIGH

Sending too many requests is invasive on the PLC which needs to conserve CPU cycles to perform its control dutiesEngage Device WG and discuss with them how to handle this
DeviceZigbeeMissing

LOW

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
DeviceLoRaMissing

LOW

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
DeviceGPSMissing

MEDIUM

Could a GPS DS serve to get the coordinates (lat/long - 2 floating point metrics) from the gateway?Assess resources to develop this
DeviceProfinetMissing

LOW

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 EdgeXAssess resources to develop this
DeviceDDSMissing

MEDIUM

DDS is used in drilling for data messaging on critical itemsAssess resources to develop this
SupportRules Engine / Analytics



SupportLoggingNeed to be able to specify persistency policies for type of logs

HIGH

Different logs are required for liability purposes and can be assessed in case of incidentsEngage Core WG and discuss with them how to handle this
ExportClient Registration & DistributionMissing mechanism for backfilling historical data. (perform an export job from start-timestamp to end-timestamp)

MEDIUM

Retrieve historical data back to the cloudEngage Applications WG and discuss with them how to handle this
ExportClient Registration & DistributionMissing Osisoft PI Export Capabilities

HIGH


Vertical Solutions WG will develop this. Sync with Export WG.
ExportClient Registration & DistributionMissing InfluxDB Export Capabilities

HIGH


Vertical Solutions WG will develop this. Sync with Export WG.
SecuritySecurityNeed to lock down access to EdgeX from unathorized access

HIGH

High security concerns


Code

If specific code addressing some of the identified gaps will be implemented as part of this project, the contributor will submit a PR on the relevant github repository.


Current status

Waiting on v0.5 release.
