    Is it possible the Modbus TCP/IP network to include more than one master device?

    @vanhetgoor 3 ปีที่แล้ว +2

    This talk gives much insight, but I must say that back in the old days a lot of thing could be improved. Silly things like Word Swap could have been prevented if from the start on the rules would be followed strictly. Time and money was spilled, confusion never eases communication.

    What does protocol means?

    • @haydenhoodless2055
      @haydenhoodless2055 3 ปีที่แล้ว +4

      Protocols are a set of rules and practices that are used in communication.
      In order for communication to happen between two or more parties, whether it be human beings or electrical devices, there must be ground rules in how it's done.
      Think about two people communicating.
      When two people talk, they have to agree on a language to use, it makes little sense in two people speaking different languages to eachother if neither of them understand the other.
      And they have to agree on timing and how messages are presented to eachother. Are they speaking in the same room? Are they texting? If they're not in the same room, and one person is choosing to communicate by writing messages on a piece of paper which can't be seen, and the other is speaking to a wall and can not be heard, communication can't happen. They also can't communicate if they're both speaking to eachother at the same time.
      The agreements and rules two people make when communicating, albeit not done necessary consciously, are protocols.
      Likewise, two or more devices can't communicate with each other without using the same protocol. There's no point in one device sending serial binary messages over a copper cable if the other device is expecting messages to come in morse code manually entered by an operator.

    Can some one tell me i m getting confused RS-485 support 32 slave /247 slave

    • @brianmurphy5150
      @brianmurphy5150 2 ปีที่แล้ว +2

      You can have 31 slaves on a single segment but can have a lot more if you have repeaters, up to 247. You are allowed 32 nodes per segment but for the first segment only 31 slaves as the master/client is considered a node

  • @Happy-cz8ft
    @Happy-cz8ft 6 หลายเดือนก่อน

    I think you are confusing "Modbus" and "RS-485" characteristics. Attributing ones attributes to the other makes it more confusing.

    • @bright601
      @bright601 2 หลายเดือนก่อน

      He is not confusing anything. RS 485 is not a communication protocol. It is simply a cable that can also be used in modbus TCP/IP. It is only a physical layer specification that can be part of modbus over Ethernet (not serial).

    • @Happy-cz8ft
      @Happy-cz8ft 2 หลายเดือนก่อน

      @@bright601 Thank you for the knowledge. If I may ask, how does a physical layer dictate how many nodes can be on a loop? (copper is just copper) I've always thought that part of the "RS-xxx" standard was a communication protocol. I'm just hopping to get a better understanding

      @@Happy-cz8ftHi, I suggest you read and research about the OSI Model. Hopefully it clears things up.
