Profinet communication with AXC 1050

Hi I am Jorge

 

I have an AXC 1050 PLC , working with a Profinet UPS, and I want to get that info from de AXC 1050 since an AXC 2152 with Profinet Communication.

I used the information that i found in this forum to establish the Profinet communication between 2 PLC, and i think i have no problem with that ( I attached photo ), because my PLCnext AXC 21152 can read the diagnostics about the condition of my AXC 1050, but  can´t read the info about the UPS. I don´t know if I have to make an structure or an array to read with my PLC next,  or I can use the RDREC to get that info.

 

So...basically i want to transfer the UPS info since PCworx to PLCnext Engineer

 

Can you give me some guide to reach my goal?

    Hello Jorge,

    the simplest and most efficient way is data exchange via PN-IO data. Please see the similar question under following link:

    If you have additional questions, please don't hesitate to ask!

    Best Regards

    Hi Eduard

    Thank for your help.

    I have already read that post before, and I don´t know if maybe I am making any mistake to do the process from video.

    The name of variables for me is DI2048, DO2048, and the video is with 4096 ending, I think that it´s something just for my version firmware (2020.3 LTS)

    I have already created the variables in main program (attached photo), but when i tried to make the port link in PLC next section, I can not find the correct way to do it. In the video, Martin makes that , linking the DI4096 with the variable PN_Inputs and DO4096 with PN_Outputs, thats it´s logical of course, but when I tried to do it, only have the acces to link inputs and outputs, and thats not seems correct.

    Maybe i failes with another step, can you give more information about it?

    Hello Jorge,

    please create at first the Datatype PNIO_256 (Array of 256 Bytes) and then create the Port-Variables of datatype "PNIO_256" as showed in the Video. It is neccessary, because the AXC1050 controller has 256 In/Output Bytes.

    Under Component->Datatype define new Type:
    TYPE
    PNIO_256: Array[0..255] Of BYTE;
    END_TYPE

    Best Regards

    Eduard
