must be completed. If this was not made, the user is
being informed about this and can immediately make up for
this test. For the
Test with 1 term.
, the terminator at the bus
end opposite to the
NetTEST II
must be switched on and set
under current. With a DP Slave unit or another passive bus
participant, the plug can be connected directly, the terminator
added and the unit switched on. If the unit at the end of the
line segment is a PROFIBUS Master, take care that the bus
participant does not actively send data onto the bus. This can
e.g. be realized by a bus disconnector. Via the bus
disconnector, the bus terminator in the PROFIBUS plug is
supplied with power, but the bus line is interrupted by a
mechanical switch in direction to the line segment.
Upon conclusion of the test the result will be displayed on the
screen.
If no error is detected with the
Test with 1 term
on the
PROFIBUS segment, a "positive acknowledgement" will
appear, according to the following figure.
