System integration is defined as the process of bringing together the component subsystems into one system and ensuring that the subsystems function together as a system.

A system is an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality. System integration involves integrating existing often disparate systems.

System integration (SI) is also about adding value to the system, capabilities that are possible because of interactions between subsystems.

Standardized communication hardware interface between HMI/SCADA and PLC. The standard interface today is Ethernet.

Standardized communication software interface between HMI/SCADA and PLC. The standard interface today is OPC UA.

Standardized operator interface on HMI/SCADA. New HTML5 technology provides some of the best user experiences in many fields. In the future HTML5 will be the major technology used for user interfaces.

 

The Goal

Standards compliance to ensure a future proof design:

  • HTML5
  • OPC UA Ethernet
  • TCP/IP

 

System architecture:

  • Low complexity
  • High flexibility
  • Modularity
  • Scalability

 

The Standard

OPC Unified Architecture (OPC-UA) is the data exchange standard for safe, reliable, manufacturer- and platform-independent industrial communication. It enables data exchange between products from different manufacturers and across systems.

 

“The interfaces between the FPSO and subsea equipment were more extensive than expected and required close management with the topsides, hull and marine and Christmas tree contractors.

Problems were encountered with the topsides terminations, control system interfaces, corrosion management, flow assurance and downhole instrumentation

Ensure all equipment suppliers have clear responsibilities for interface control and are keyed into the management interface systems.”
