BEI Sensors MHK5 Absolute Hollow Shaft Encoder - Manual (Page 9)

3 Device Configuration
The Absolute Encoder with Profibus-Interface can
be programmed according to the needs of the
user. The GSD-file has to be installed in the used
software tool. The user has the possibility to
choose different encoder configurations.
Parameters and functionality depend on the
selected encoder configuration. -Absolute
Encoders Type „MHM5-MHK5-DPC1B-XXXX-
XXXX-0CC“ support all configurations described in
the following, i.e. there is no functionality limitation
due to the hardware. Additionally to the
configurations „Class 1“ and „Class 2” (according
to the Profile for Encoders) the Encoder offers
configurations with manufacturer-specific functions.
By choosing a certain encoder configuration
parameter and configuration data are determined.
These data are stored in the profibus master. They
are transmitted to the slave (encoder) when the
profibus network is starting up („DDLM_Set_Prm“).
It is not possible to change parameters or
configuration during the normal operation of the
device (exception: “Commissioning Mode”, see
chapter 5.3).
After receiving configuration and parameter data
the absolute encoder enters the normal operating
mode (cyclic data transmission –
„DDLM_Data_Exchange“). In this mode the
process values (e.g. the position value) are
transmitted. Data length and format are determined
by the user when selecting a certain encoder
configuration.
