Elements on the front plate
The rotary switch is used to set the units place (first switch from top) and the
tens place (second switch from top) of the station address.
The hundreds place of the station address depends on the setting of the toggle
switch (upper position = 1 x 100, lower position = 0 x 100). Valid station ad-
dresses are between 3 and 124.
Note
The software limits the station address to the range from 3 to 124.
A change in station address does not become active until after a restart of
the control.
Pressing the RESET button on the module interrupts the interface to the
control and the SINEC L2-DP field bus and initiates resynchronization.
Note
Pressing the RESET button during cyclic operation of the module causes the
control to stop and is therefore only permitted while the control is being
started up.
The status display (FAULT and RUN LED) can indicate the following states
of the SINEC L2-DP slave module.
RUN (green)
FAULT
(red)
Meaning
off
on

Via the interface X111 (SUB–D, socket, 9–way), the slave is connected to the
SINEC L2–DP field bus.
