SIIS L2 topology Provides subsea mateable interfaces from subsea control systems which do not have to be predefined in terms of the instrumentation to which they will subsequently be attached. The communication protocol is CANopen (CiA 443) over an ISO 11898-3 (fault tolerant) physical layer [default bit-rate 50kbit/s]. SEM SEM MB SIIS level 2 supports multi-measurand devices that can be distributed on a multidropped star topology Inbuilt CAN node self detect and configuration; Diagnostic data tunnel access to the device layer MB Basic CANopen interface configurations 9

OPC-UA Interoperability OPC-UA interoperability OPC UA provides an information model framework, which can expose vendor defined information in a standard way. Importantly, all OPC UA clients are expected to be able to discover and use vendor defined information. Subsea Vendor DCS Vendor or other OPC-UA Client System Implementation / configuration nodeset file The MDIS specification is an example of an OPC UA Information Model designed to meet the needs of developers and users in the offshore oil and gas industry.
MDIS OPC-UA Objects Choke example MDIS OPC UA Objects Choke example The object properties and behaviour is specified in the MDIS specification. The protocol is open and tools to test and verify is available. It shall be easy and cost effective to integrate and test a DCS and MCS system in near future.
