    Hi, José

    the correct part number is the 8A.37V70-2204 80188-Einkartenrechner MIT LWL-SCHNITTSTELLE

    we call this board SPS station slave, normally has e-proms with its version, pay attention of this data , but you must order the board with the label stick behind the board so will be better take pistures of both sides of the board and share...

    question: how do you find this board is defective?, have you test interchanging this board with another unit ?
    you can discard the e-proms just copying from another board and burn a new ones or yhe easy way interchanging with a good one...

    this board has two functions, close the loop of the optic fiber and controll inputs and outputs of the station...
    sometimes the DC source at station suddenly turn off very short time then the station disconect from the BUS , you must discard the DC source at station first.

    Hi sir:

    Normally, SPS= PLC(programmable logic controller)
    the way to troubleshooting is looking for the Status LED's, in the Input +Output boards.

    The Green Led's will be On when switch, limit switch,sensors, solenoids, relais, contactors are O.K and Red Led ON.

    Finally the parts number is o.k but need the serial number +model exactly, and your country in order to quotate the freight for delivery, in case that you decide.
