Device Address Not Found

What does -2 mean?

The specified device address could not be located on the PROFIBUS. This can be due to an incorrect address parameter in the `ioCtl` call or the device not being present.

• Device address configured in system does not match physical address on bus.
• Device is not connected to the communication bus or is powered off.
• Incorrect bus termination or signal integrity issues preventing device discovery.
• Faulty device hardware preventing it from responding to address requests.
