    Hi,

    I was wondering if there is a way to limit the number of allowed on-line connections at a time to a PLC?

    Like can you somehow set in the PLC parameters that only 1 'connection' can be on-line in the device at a time?

    Thanks

    Edit: I'm referring to connections from the TIA portal - not HMI / ethernet connections and so forth

    Hi,

    I was wondering if it's possible to detect a changed/updated value in a data block even if the value remains the same as before.

    The reason I ask is because we have a SCADA system providing a setpoint for a temperature every x minutes. The value of the setpoint can remain unchanged for hours even days.

    However we still want the PLC to be able to detect wheather it's setpoint is updated every x minutes or not.

    Any good solutions?

    Thanks!

    Hi,

    I was wondering if anyone have experience with Tia Portal Step7 v.14 and Step7 Classic v.5.5 located on a remote server?

    We have several persons working on our PLC's. As it is they all have their own PC with Step7 + licenses.

    We were thinking about moving the software environment onto a server to reduce license and maintenance costs.

    Does anyone else have this setup? If yes do you have any tips or comments? Pros/cons?

    I already know now that you cannot autodetect/configure new devices from a remote server as the Step7 detection protocol doesn't work through a router. We can live with that.

    We need both TIA Portal and the Step7 Classic on the same server.

    Thanks
