    Default CP2000 Network Problem

    Hi all

    I'm working in printhouse with 3 Heidelberg presses.
    My problem is that only one of them see's the computer which contains our ppf-files.
    As far as I can see CP2000 in all 3 presses are set up the same way, at least when it comes to user/password in the ppf-interface.
    And I can see/ping all three machines from the computer with the ppf-files.

    What am I missing?
    Any clues anyone?

    Thx in advance

    have your IT guy check the PATH setting in cp2000.

    As far as I know, they have put the same settings in all three machines.
    PATH/User/Psw. But maybe they missed something.

    And IT departements are not so easy to deal with, because they never do anything wrong

    if all the settings are right then make sure the network cable is properly seated in the IPC.
    i did have a problem once that wound up being a bad network connection. also, if the IT dept. made any changes to the settings or re-installed them, you must reboot the press and sometimes it may take a few times for the settings to take.
    Other than that, the problem may not be on the press end, dare i say, it may be on the other end.
    good luck and let me know what u find

    It's been my experience that the switch/hub port that a press is ultimately plugged into must be configured for 10MB (10baseT) as that is the speed the IPC's communicate at.

    If the port is configured for auto-negotiation, 100MB (100baseT), or even gigabit, connectivity maybe intermittent at best.

    Best regards,
    Jon

    Hello there, I have tonnes of Heidelberg service notes at home I will put on a further post later if you need it. I will say this first, check the path name in CP2000 on each press, it looks at a folder (which must be named differently) on the PPF interface not the other way round, you are using Prepress Interface? The speed of the network switch has no impact 10bT, 100bT, 1000bT or Auto makes no difference. The version of CP2000 may, but I doubt it, they do all have the PresetLink option?

    Hi David,

    Not to disagree with you but port speed absolutely matters (at least in our case it did). Until we set the port speed to run only at 10baseT speed, press/network connectivity was intermittent (even when the ports were configured for auto-negotiation).

    Best regards,
    Jon

    I agree some networking equipment has issues with auto negotiation. I had a cisco switch/router that would only connect when set to 10BT

    We shall have to agree to differ, I cannot explain nor will I engage in an argument with the experience you had. For me, in the many installations I have been involved with this has never been the case or issue.
    I'm sorry that you did, as it works lets leave it, but that has made me wonder why as CP2000 is a 10/100 device (I trust you are using the correct network pot in CP2000?). Do you use other features such as PlateOnDemand, QualityMonitor, Shop Floor Data Collection or just transferring the PPF file from the workflow to CP2000? As this will impact on CP2000's performance, JMF transfer if it is sitting on 10bT network?

    But as some assistance to the original thread I have attached a pdf that may offer you some help in your network setup.
