QUESTIONS



QUESTIONS FROM THE CONFERENCE FLOOR

To ensure that no-one goes away with unanswered questions we give Delegates the chance to pose their questions in advance of the Conference so that our speakers will have time to research the answers, which will be addressed during the sessions.
 
Hence, if you have a difficult question about PROFIBUS or PROFINET that you think should be answered for the benefit of all at the Conference, please for forwarding to the Papers Committee. A selection of questions will be placed on the website - anonymously of course.
 
Here are a selection of questions received for the 2006 Conference:
 
  1. Cables come from various manufacturers with differing impedences. Is it prudent to buy cable with a lower impedence than say the 44 ohm/km as specified by Profibus?
  2. Profibus DP has a powered terminating resistor but PA does not. What is the difference?
  3. The current tools used to configure Profibus networks look and feel old fashioned and are difficult to use. End users want better, simpler tools more in keeping with modern computer operating systems. When are we going to get them?
  4. How has the PROFIBUS Profile specification helped the end user of instrumentation?
  5. Can high availability systems be justified for relatively simple processes (i.e. water treatment) ?
  6. What are the typical options for connecting Profibus devices in a Hot/Standby PLC system ?
  7. What are the important factors that I have to take into account when considering implementing a wireless network?
  8. What about safety over wireless? How can that be achieved?
  9. There is an increasing number of software packages involved in the new safety technology of devices and PLCs. Software without errors will not be possible. How can we live with this "uncertainty"?
  10. The numerical approach of IEC62061 is presuming the availability of tools to support the life cycle management of functional safety. When can we expect these kind of tools? Will the system manufacturers take over the responsibility for the correct calculation of SIL, PFD, and alike?
  11. Currently, all different kinds of fieldbuses are rushing to integrate safety into their solutions. What is your expectation on the long term impact on automation technology and architectures?
  12. PROFIsafe claims more than 2000 applications in the process industries. We haven't seen any PROFIsafe PA Device so far. How come?
  13. Safe peer-to-peer communication from an E-Stop button directly to a drive seems to be a better solution than using the detour via a safety PLC? Why can't we see such a solution in reality yet?
