Description

The subindices have the following function:

  • 3240h:01h (Special Function Enable): This bit allows special functions of an input to be switched off (value "0") or on (value "1"). If input 1 is not used as, e.g., a negative limit switch, the special function must be switched off to prevent an erroneous response to the signal generator. The object has no effect on bits 16 to 31.

    The firmware evaluates the following bits:

    • Bit 0: Negative limit switch
    • Bit 1: Positive limit switch
    • Bit 2: Home switch
    • Bit 3: Interlock

    If, for example, two limit switches and one home switch are used, bits 0–2 in 3240h:01h must be set to "1".

  • 3240h:02h (Function Inverted): This subindex switches from normally open logic (a logical high level at the input yields the value "1" in object 60FDh) to normally closed logic (the logical high level at the input yields the value "0").

    This applies for the special functions (except for the clock and direction inputs) and for the normal inputs. If the bit has the value "0", normally open logic applies; for the value "1", normally closed logic applies. Bit 0 changes the logic of input 1, bit 1 changes the logic of input 2, etc.

  • 3240h:03h (Force Enable): This subindex switches on the software simulation of input values if the corresponding bit is set to "1".

    In this case, the actual values are no longer used in object 3240h:04h, but rather the set values for the respective input. Bit 0 corresponds to input 1 here, bit 1 to input 2, etc.

  • 3240h:04h (Force Value): This bit specifies the value that is to be read as the input value if the same bit was set in object 3240h:03h.

  • 3240h:05h (Raw Value): This object contains the unmodified input value.

  • 3240h:06h (Input Range Select): This can be used to switch inputs – that are equipped with this function – from the switching threshold of 5 V (bit is "0") to the switching threshold of 24 V (bit is "1"). Bit 0 corresponds to input 1 here, bit 1 to input 2, etc.

  • 3240h:07h (Differential Select): With the inputs, this subindex switches between "single-ended input" (value "0" in the subindex) and "differential input" (value "1" in the subindex) once for all inputs.
  • 3240h:08h (Routing Enable): The value "1" in this subindex activates Input Routing.
