Avoid stress on connectors and bus stations
Avoid stress on connectors and bus stations which might be caused by the
device's own weight. Ensure proper strain relief by using suitable supports,
cable ties, etc. When this is not possible, you need to select a different
connection point to avoid damage.

Using the security lock port
When using trend logging, the PROFIBUS Tester 5 is typically operated in an unattended
manner over a prolonged period of time. You can connect a Kensington lock to the

lock cable to a fixed object and install the other end of the cable to the security lock port.

Test locations
The PROFIBUS Tester 5 can basically carry out tests anywhere on a physical PROFIBUS
segment. Note that the use of repeaters creates separate physical segments that each

tests at the beginning and at the end of each physical segment. If these test results
indicate problems that cannot be clearly classified right away, you should carry out one or
more additional tests at the center.

Simple connection for tests during system shutdown
If all bus stations provide D-sub connectors with an additional service socket, you can
simply plug in the PROFIBUS Tester 5 at that socket (see figure below). If a D-sub
