  • One way of PLC-PLC Communication.
    Very easy to send Outputs from PLC to PLC.
    Works for:
    S7-1500: All
    S7-1200: From Firmware Version 4.0
    S7-300 From Firmware 3.0 (Only when having PN)

    A nice fact is that only one of the PLCs needs to support and have the possibility to select operation mode - I-device. The other only need to match the area set-up in the other one.

  • @whitemonkey7932
    @whitemonkey7932 2 ปีที่แล้ว +1

    Thanks...lots of conflicting info and I'd like to get the software finished and hardware config ready - It seemed that it was necessary to use PUT/GET which didn't seem logical when the config was already carried out at hardware level. I'd guess that whilst not very elegant, there would be no problem in copying Mbits or extracts from DB's with a move to the output area, to be translated again at the coordinating PLC.
    Once again thanks...

    Hi Hegamurl!
    Very good job indeed!
    Sorry, as far as I understood the memory space that we need to save in IO Controller is 1 byte? I mean when you press switch I0.0 in IO Device that means a full byte will be true I 1 in IO Controller:
    An other question would be.. Could I connect more than 2 CPUS, I mean, when press I0.0 in PLC 1, then send a signal to PLC 2 and PLC3? I am confused sorry..
    Thanks!

    Hi, I'd like to run two machines simultaneously for redundancy. Each PLC should run independently but in any case of failure, the other one shall take over. So, If a failure occurs I'll transmit one bit from one PLC to the other.
    This should work in both directions (Bidirectional).
    Is this the recommended way to do the communication, or would it be better to do it with the put command?
    Thank you in advance.

  • @aamirawan7998
    @aamirawan7998 2 ปีที่แล้ว

    You gave the address i0 for the IO controller (receiving PLC) in the operating mode which means when you turn on the button i0.0 should have turned on in the IO controller but rather I1.0 turned on in the simulation of the controller (receiving PLC). I know that you set i1.0 address to physically connect the button to the I-device (sending PLC) but you set i0 for the IO controller but still i1 turned on for the IO controller as well. Why?

    hey Hegamurl!
    I need your help that I have a question about PLC communication and sequential programming. I hope I could describe it clearly here:
    I have one project with two PLCs(two S7-1200). I follow you to use I-device to set PLC2 as I-device and PLC1 as IO controller. I set two communication areas: Q100 from PLC2 to I100 in PLC1; Q100 from PLC1 to I100 in PLC2.
    PLC2 has one sequential program in its step 2 and step 4, it gives the task to PLC1 for one assignment (axis1 move absolute). The program should run as automatic cycle. But in reality, it ran several cycles and stopped. The cycle time was random. I am really getting stuck. I know it is difficult to describe the problem and it may confuse you. I just want to have a try to see if I am lucky enough to get some tips.
    Thank you!

    • @hegamurl7434
      @hegamurl7434  4 ปีที่แล้ว +8

      Of course you can! OPC UA would be a solution, but not my preferred one (the biggest advantage of it is that you can go across different networking types). As both CPU's are using PROFINET I would use "TSEND_C" and "TRCV_C"... with those you can communicate with basically any Ethernet device, as it uses standardized ethernet packages. One of my next videos will be about that!

      If you are using "PLCSIM" it won't work, because the simulation does not simulate the "hardware" part of the PLC, which networking belongs to.
      To simulate such behaviour, you would need "PLCSIM Advanced", which "emulates" the hardware

      Yes, correct! The area for sending is flexible, but an analog value takes one word/ two byte.
      Anyhow, it would be better to send TWO WORD rather then two byte, as each analog input uses two word (even though the value is transformed to INT which is one word). I don't know what it uses the 2nd word for, but better be safe than sorry 😅

      Yes, you can. It just sends bytes of information and it can be anything. In this video we have only one byte sent, but you can send much more. Ex. define your Address in IO controller " I 1000...1099" and I-device respectively "Q 1000...1099" and you can send 100 bytes in memory area 1000 - 1099.

    hello , it does everything step by step as you ,but I use PLCSIM and it does not work properly. Can PLCSIM be a problem?

      Depends on which version of PLCSim you use... if I remember correctly it only works with "PLCSim Advanced" and not the basic version, as it has to simulate the network interface

    Hi. Your videos have been a great help to me in my automation career. Cann you do a video about s7 1200 using Siemens access point , w774-1 rj45 to communicate between other access points connected to each of their own cpus?

    why do you have to dedicate an entire byte to a bit function?
