Connection of the LS4
Integrating the LS4 into the PROFIBUS network requires the
GSD file of the LS4. It is delivered with the LS4. Install the GSD
into the hardware configuration of STEP 7 ( Menu Options ->
Install new GSD). Subsequently, the LS4 is available in the
hardware catalog (within the hardware configuration of
STEP 7, see following figure).
Externally, the LS4 has five male/female connectors
(X1, X2,...,X5).
Connect these male/female connectors as follows:

Here you connect a push button (NO)
(considered in chapter 3 in the table
"Hardware components"). This button has
two functions:
■ Unlocking the scanner-internal starting/restarting
lockout, if it has been
activated. In this example it has not
been activated. However, a restarting
lockout has been realized in the failsafe
S7-program.
■ Error acknowledgement, if the LS4 is in
failure mode.
If the LS4 is the last device at the PROFI-
BUS, a standards compliant terminating
resistor should be connected (this was the
case in our test run).
–
Connected to the COM interface of the
PG/PC on which the programming software
LS4Soft has been installed.
Note
The cable outlet of the PC adapter at LS4 must point in the
direction of the detection zone. The PC adapter should
only be connected in the installation phase or for control
purposes.
