Changing the SIMOLINK receive address on SLE-DP

When the SLE-DP power supply is switched on, the SIMOLINK receive
addresses set on the DIL switches are transferred, since, at this stage,
the PROFIBUS interface is still running up with the PROFIBUS master
(if the PROFIBUS interface is not activated, the addresses set on the
DIL switches remain valid). With switch S1.5 in position 1, the SLE-DP
can be started with this receive address via SIMOLINK.
As soon as the red PROFIBUS error LED goes out and address bits
are set in the PROFIBUS output data word, these bits are OR'd bit-
serially with the DIL switches of the receive telegram when DIL switch
S1.5 is set to position 0 or when the control bit in the PROFIBUS output
data word is set.
The SLE-DP module can be activated/deactivated via DIL switch S1.5
and the transfer control bit in the PROFIBUS output data word.
Changes to the DIL switches and in the output data word are accepted
only when the SLE-DP is deactivated. Both sources of activation
command have equal priority. However, the SLE-DP can be activated
via the transfer control bit in the PROFIBUS output data word only if
DIL switch S1.5 is set to 'SLE active'.
DIL switch S1.5 implements the transfer sequence of receive channel
and address via the switching sequence 1 to 0 to 1. The starting
sequence via SIMOLINK must then be initiated to enable pulse output.
If S1.5 is switched to position 0, the SLE-DP is deactivated. No pulses
are output and the status in the SIMOLINK write channel and the
PROFIBUS input data word equals 'SLE-DP not active'. The DIL
switches are read in simultaneously and OR'd with the bits of the
receive channel and address from the output data word. The results for
receive channel and address are checked; if an error is detected, this is
indicated by the LEDs on the front panel and by bits in the input data
word. The settings of the remaining DIL switches are still transferred
again. After the SLE-DP has been activated (S1.5 to position 1), the
encoder waits for the starting sequence via the new (or unchanged)
SIMOLINK receive telegram.
