Description: FreeMODBUS 是针对通用的Modbus协议栈在嵌入式系统中应用的一个实现。Modbus协议是一个在工业制造领域中得到广泛应用的一个网络协议。一个Modbus通信协议栈包括两层：定义了数据结构和功能Modbus应用协议和网络层。在FreeMODBUS的当前版本中，提供了Modbus Application Protocol v1.1a 的实现并且支持在Modbus over serial line specification 1.0中定义的RTU/ASCII传输模式。从0.7版本开始，FreeModbus也支持在TCP defined in Modbus Messaging on TCP/IP Implementation Guide v1.0a中定义的TCP传输。Freemodbus遵循BSD[1] ，这意味着本协议栈的实现代码可以应用于商业用途。-FreeMODBUS is common Modbus protocol stack for embedded systems applications in an implementation. Modbus protocol is an area in the industrial manufacturing of a widely used network protocol. A Modbus communication protocol stack including the two: the definition of a data structure and function of Modbus Application Protocol and network layer. In FreeMODBUS current version, provides a Modbus Application Protocol v1.1a implementation and support for Modbus over serial line specification 1.0 as defined in RTU/ASCII transfer mode. Starting from the 0.7 version, FreeModbus also supports TCP defined in Modbus Messaging on TCP/IP Implementation Guide v1.0a defined in the TCP transmission. Freemodbus follow the BSD [1], which means that the protocol stack implementation of the code can be used for commercial purposes. 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: |
