    Class: 0x69
    Instance: 0x1
    Attribute:
    Service: 0x4D

    This works and looking at the auto ID software terminal screen it shows data that is read, the part i can not figure out is how to retrieve that string into the PLC (using BRX Internal Ethernet port with device created for for SR-752 set to EtherNet/IP Explicit messaging)

    Help!!!!!!!
    Host is the manufacturer of Do-more, so you could also post your query HERE.

    RX & WX instructions are only for PAC to PAC communications. Can your device communicate Modbus? A quick look at the manual, and I am thinking no. The PAC can send ASCII string data via Modbus only.

    You would most likely need a ASCII to Modbus Ethernet or Serial gateway, did a Google search and came up with the below;

    The scanner specifications do not show any Ethernet protocols compatible with the P3000

    The switch is Trendnet TPE-S44. I have the PAC connected to a Non powered port.

    After reading more from the Keyence manual, it looks like i should be using RX and WX commands from the PAC to control BCS. Is this correct?

    What type of switch are you using?

    check your switch settings... can you turn off the power to individual switches? If so, you should be able to connect that port to an AD PLC.

    Thanks for the quick reply. I will look over the manual again.
    I should have mentioned that I have 2) SR-751 that are routed through a switch with POE.

    >SR-751

    just received two of these today for installation later this week. The manual, starting at 8-1 (pg 71 of the pdf) shows some examples of formatting, and has this tidbit :

    There are 2 types of commands used with the SR-750 Series:
    These commands and responses are common to RS-232C communication and
    Ethernet communication. The ASCII codes are used for the transmission and
    reception.


    I usually use RS-232 with these b/c AD PLCs aren't POE compatible.

    started a topic Capture barcode over ethernet

    Capture barcode over ethernet

    Iím working with:
    P3-550
    Keyence SR-751
    Very limited PLC programing experience.


    Is it possible to trigger the barcode scanner and capture ASCII string all over ethernet? What communication protocol would I want use? Anyone up for providing an example?

    All examples I have found only show using BCS over a serial connection.

    Any and all guidance on this matter would be greatly appreciated.
Working...
