PROFIBUS Tester BC-700-PB - User Manual
SK1, SK2 and SK3 segment couplers, e.g. from Fuchs (or sometimes under
a different label)
Irrespective of the connection types used for the field devices, the fieldbus couplers are
usually installed in a control cabinet, and the PA output is connected there via terminals.
Connection to MBP-IS is not allowed.
You can use the connection points of bus stations or access points inside the field
distributors as connection points. Establishing the electrical connections required for
measuring may vary from system to system and might not be possible during operation.

Hint
An appropriate connection point is located directly at the DP/PA coupler. At
this point, the tool can continue to analyze the bus communication even
when lines are interrupted. The measurements are not affected by repeaters
or field barriers.
