Multi-HIL system architecture parameters

In this section, modeling parameters for multi-HIL models are listed and described.

  1. Electrical variables between two devices are sent through the device coupling element. Depending on the type of coupling element, the number of variables that the SPCs send are:

    • Single Phase Device Coupling - one variable
    • Double Phase Device Coupling - two variables
    • Three Phase Device Coupling - three variables
    • Four Phase Device Coupling - four variables

    For example, with a HIL 602+ device, it is possible to connect one SPC to other devices with at most 2 Three Phase Coupling Devices.

  2. Independent of the previous constraint, it is possible to transfer up to 16 electric variables from a part of model assigned to one HIL device to other parts of the model. This restriction is made because of the transferring capacity of HIL devices.
  3. Signal processing variables are transferred between devices using the Device Transition component. Every Device Transition component defines one stream. This restriction simply means you can transfer up to 16 signal processing variables through one Device Transition.
  4. Independent of the previous constraint, there is a maximum number of Device Transition components between two devices. For example, you can connect two HIL 602+ devices with a maximum of 4 streams (each with a maximum of 16 signal processing variables).
  5. All paralleled HIL devices are synchronized with the master HIL (the HIL with ID0).
