What are the communication network architectures of various well-known DCS systems (ring, bus, MODBUS, Hart, etc., from the field to the control room)? What are their respective communication modules? I hope fellow sailors can provide detailed guidance based on their knowledge of the system. Thank you!
The Honeywell TDC3000 I have used employs a bus-based communication network, while the Zhejiang University Zhongkong JX-300X system uses a star-based communication network.
Siemens offers a variety of network architectures: industrial Ethernet, bus structures; the DP network can be used to form bus networks and token networks
The topic raised by the original poster is quite broad; it would take an entire paper to explain it properly. It would be better if you made the issues you want to clarify more specific, so that others can give you advice.
We use those from Fosporo: wired, ring, star, and tree topologies; we use the star topology
