3.2 PROFIBUS checklist
The following checklist supports you when planning, projecting and
installing a PROFIBUS plant with the IQ S
ENSOR
N
ET
. For smooth
operation, you should be able to answer all questions with "Yes".

Is the [bus system] (bus segment) installed without branch lines?

Was the correct PROFIBUS cable used (cord type A according to
EN 50170)?

Are the poles of the signal lines A line and B line correctly connected
at all bus connections?

Is it guaranteed that there is no short-circuit between A line, B line
and cable shielding?

Is the shielding installed free of interruptions?

Are the guidelines for shielding and grounding being observed, and
doesn't any unallowed potential equalization current flow
via the shielding?
