    Dear All
    I am facing measurement problem,
    I get the error "No connection with the subscriber: 0". On the NET-I (1032) block, the red indicator is on, we tried
    move the unit to another controller - everything works when turned on, the red indicator lights up and after a few seconds
    switches to green. What do you think might be the problem and how to solve it?

    Hi sir:
    1)Measure Clock for CPU:

    Check the frecuency with frequency counter or a DMM included frecuency counter( like Fluke DMM)


    2)Reset CPU:

    reset cpu see the attached schematic.

    3) Components ; Rusting+Dry+Colder joint solders

    4 ) Ribbon or flat Cables; Corroded+Broken

    Thank. All dropped the CPU, the problem remained. The feeling is that Flash memory is not working.
    If anyone has a program to check the Flash memory, please tell me.

    Hi sir:
    1) You must measure the power supply for the CPU : Vcc ! other wise the Reset will NOT effective.(attached is there example for CPU 8085 for Schematic Pins)!

    2)Measure the clock as I did indicated, after if the power supply is o.k, otherwise, will NOT result

    3) Reset again, if everything is o.k.

    4) If after Reset is NOT working, you must Need to Reinstalling the Software , that can be Corrupt!

    Blessing

    The electronics engineer cannot measure the frequency on the CPU. We removed the controller, installed it in the adjacent binder and it works. Conclusion: Flash RAM does not work or memory is erased.
    The memory contains 4 microcircuits, 2 ROM and 2 RAM. Battery voltage 1.4v and 12v. Can anyone find a circuit or firmware for this memory strip?

    ok, sir
    1) the battery must be replaced.

    2) need the ID plate from the machine+ label Version of RAM, for the firmware.
