Brief Instruction FLEXtra® twinRepeater
Application and functional description
In spite of its compact design, the FLEXtra® twinRepea-
ter is a completely normal PROFIBUS Repeater.
It regenerates the signals in flank slope, level and duty
cycle.
Mounting
The FLEXtra® twinRepeater is suitable for mounting
on a DIN rail. It is engaged as shown on the picture.
Switching repeat function
A switch labelled with “Repeater” is installed under the
“Power” LED for switching off the repeat function. In
the “OFF” switch position, no communication between
the two interfaces is possible.
Note: The switch to „OFF“ is useful for pulling and
plugging of segments.
Connection of the PROFIBUS line
The PROFIBUS is plugged into the device using
commercially available PROFIBUS connectors. Refer to
the documentation for the PROFIBUS connectors how
you connect the connectors correctly.
Connection of the power supply
The power supply of the device is connected using
the power supply connections on the bottom left of
the device. The assignment can be seen in the picture.
Terminating resistors
Check the setting of the bus terminator (switch on the
top side of the plugged-in PROFIBUS connector).
If the twinRepeater is located at the end of a segment,
you must activate the bus termination (ON).
If the twinRepeater is located in the middle of a
segment (e.g. to open a branch line), you must deacti-
vate the bus termination (OFF). Some examples can be
found on the following pages.

LED description
Note: if no baud rate is detected, the repeater restarts every 8 seconds. The restart takes approx. 2 seconds.

Flash frequency depends on the number of invalid telegrams
(steady light possible).
Flash frequency depends on baud rate and number of participants of the port (steady light possible).
