How is M-bus connected to the field?
Thread Content
I think I understand it here, but I’m not sure if that’s correct! There are many 4-20mA signals at the site; the site uses a concentrator to convert these various signal lines into fiber optic signals (i.e., M-bus) and send them to the DCS ? ? ? ? ? ? ? Please don’t laugh at me; I don’t quite understand. If there’s something wrong, please tell me how to do it ? ?
The points at the site should use communication cables to send data packets from the bridge to the DCS communication card, where the DCS converts them into numerical values. The fiber optic connection you mentioned is used for long-distance communication, and fiber optic transceivers are required for that
I went to the site yesterday; the conversion box there consists of the signal wires from the four radars, which are combined into one set of wired connections that lead to the DCS cabinet. Is there some equipment inside the cabinet that is used to distribute the signals across this set of wired connections? ? ? ?
M-BUS? Soda meter? Is it for meter reading? ? It’s similar to the principles of communication; it’s just that the methods of communication differ
