Description: 三菱软件
OPC主要适用于过程控制和制造自动化等应用领域。 OPC是以OLE/COM机制作为应用程序的通讯标准。OLE/COM是一种客户/服务器模式，具有语言无关性、代码重用性、易于集成性等优点-Mitsubishi OPC software is mainly applied to process control and manufacturing automation applications. OPC is based on OLE/COM application mechanism as a communication standard. OLE/COM is a client/server model, has nothing to do with language, and code reusability, ease of integration, etc. Platform: |

Description: Modbus协议是应用于电子控制器上的一种通用语言。通过此协议，控制器相互之间、控制器经由网络（例如以太网）和其它设备之间可以通信。它已经成为一通用工业标准。有了它，不同厂商生产的控制设备可以连成工业网络，进行集中监控。此协议定义了一个控制器能认识使用的消息结构，而不管它们是经过何种网络进行通信的。它描述了一控制器请求访问其它设备的过程，如何回应来自其它设备的请求，以及怎样侦测错误并记录。它制定了消息域格局和内容的公共格式。-Modbus protocol is used in a common language electronic controller. Through this agreement, between the controller, the controller can communicate via the network (such as Ethernet) and other devices. It has become a common industry standard. With it, different manufacturers of industrial control equipment can be connected into a network, centralized monitoring. This protocol defines a message structure used by the controller to recognize, regardless of what network they are communicating. It describes the process a controller requests access to other devices, and how to respond to requests from other devices, as well as how to detect errors and recorded. It formulated the message domain structure and content of a common format. Platform: |

Through this agreement, between the controller, the controller can communicate via the network (such as Ethernet) and other devices. It has become a common industry standard. With it, different manufacturers of industrial control devices can be connected into a network, centralized monitoring. This protocol defines a message structure that controllers use to recognize, regardless of what network they are communicating. It describes the process a controller requests access to other equipment, if the response to the request other devices, as well as how errors are detected and recorded. It developed a message domain structure and content of a common format. When the communication on a Modbus network, the protocol determines how each controller will know its device address, recognize a message addressed to it, decide what action to produce. If you need to respond, the controller will generate and send feedback info Platform: |

Description: Within a subsea control system various industrial Ethernet protocols are implemented for process data exchange on the link between topside & subsea. Also, different types of instrumentation networks are used to collect data from sensors & intelligent devices at the seabed. In this
project different protocols & networks shall be evaluated based on criterion from OneSubsea
Processing. As a minimum the following protocols shall be evaluated: Modbus TCP, Ethernet/IP,
and OPC UA for topside - subsea communication. CAN bus (SIIS level II) and IWIS (API 17F)
shall be evaluated for collecting sensor & actuator data to the SCM. The project shall also consist of a practical implementation of industrial protocols. Platform: |
