Cabling between KL6581 and KL6583

Notice

Cabling instructions:

    • The KL6583 must always be supplied with power from the KL6581. Operation with any other power supply is not permissible!
    • The termination resistor must be switched on in the last device; set S1 and S2 to ON.
    • Use only the Beckhoff CAN cable with the order identifier ZB5100. Order quantity: in meters.
    • The total cable length (from the KL6581 to the last KL6583) must not exceed 500 meters.
    • The topology is line; stubs may not be used.
    • The line must always begin with a KL6581. The KL6581 must not be installed within the line!
    • The maximum number of KL6583 devices that may be connected to a KL6581 is eight.

    Node address of KL6583

    Cabling between KL6581 and KL6583 2:
    Setting the node address with switch S3

    S3 is for setting the node address. Each address may only be used once in the line (valid addresses: 1...8).

    Termination resistor

    The termination resistor must be activated in the last module!

    To do this, both DIP switches S1 and S2 must be set to ON.

    Cabling between KL6581 and KL6583 3:
    Termination resistor ON
    Cabling between KL6581 and KL6583 4:
    Termination resistor OFF
    Cabling between KL6581 and KL6583 5:

    Risk of confusion

    The number ‘1’ on the DIP switches is only for numbering: The ‘1’ does not mean ON!
    If a switch is set to ‘1’ the termination resistor is OFF!
