As an example, we will search for the standards for PROFIBUS-DP. This belongs to the CPF 3 family and has the profile CP 3/1. In Table 5 we find that its protocol scope is defined in IEC 61784 Part 1. It uses protocol type 3, so the documents IEC 61158-3-3, 61158-4-3, 61158-5-3 and 61158-6-3 are required for the protocol definitions.
The system is also designed to accommodate multiple wells, and integrate with the major distributed control systems (DCS) and subsea equipment types. The UMCS also offers a pre-engineered solution based on a standardized program block architecture and a common communication database via the Standard Interface, based on OPC.
The DCS G-8 is responsible for integrating Army funding, fielding, and equipping actions with the Office of the Secretary of Defense (OSD), Joint, and Army Staff (ARSTAF) organizations and processes for the purpose of meeting current and future force requirements of the Joint Force.
