This Chapter contains the technical descriptions and start-up
instructions relating to the PROFIBUS functional expansion of the
SIMOLINK Encoder. It therefore applies only to the SLE-DP encoder
model.
The receive address and address channel for the SLE-DP encoder can
be altered via the PROFIBUS-DP. This is done by OR'ing the DIL
switch position and the value from the PROFIBUS telegram bit by bit.
For the purpose of data transfer control, the method of activating or
deactivating the SLE-DP via the PROFIBUS has equal priority to the
method using DIL switch setting S1.5.
The PROFIBUS configuration and a sample program are explained
below based on the example of a SIMATIC S7 application.
The SIMOLINK Encoder SLE-DP is a passive PROFIBUS-DP slave
node with 2 bytes each of output and input data which must be
processed as consistent data (i.e. word processing permitted only on
transfer via PROFIBUS) and transmitted cyclically. It supports data
transfer rates of up to 12 Mbaud and guarantees conformity with
EN 50170 through the use of a PROFIBUS ASIC.
The term "input data" refers to data which the SLE-DP as a PROFIBUS
slave makes available to the PROFIBUS master (in this instance, SLE-
DP status and error bits) and the term "output data" to information
which the PROFIBUS master transfers to the SLE-DP (in this instance,
address changes to the SLE-DP).
Telegram type Meaning for SLE-DP
Parameter Necessary data stored in the GSD file
Configuration Identifier bytes contained in the GSD file
Diagnosis SLE-DP makes no user-specific diagnostic
data available
Change slave SLE-DP station address cannot be altered
address via the PROFIBUS
Data transfer Supported by the ASIC, but irrelevant for
control SLE-DP
