XPS-E
9 / 36
3.3 Parametrization
The parameterization data of XPS-E consists of 7 DP-Slave standard
bytes and 16 device-specific parameters bytes (User_Prm_data, ->
user_prm_len = 16). As user diagnostic data, 8 additional diagnostics
bytes are available. (diag_len = 8).
◦ For initialisation of XPS-E send a set_prm telegram. For this purpose,
use the parameters for PROFIBUS-DP and the serial interface
described in chapter 2.5.
◦ Check the parameterization with slave_diag.
◦ Then use the command chk_cfg to configure the XPS-E. Prior to that,
the configuration can be read with the command get_cfg from XPS-E. If
chk_cfg is executed directly after the initialization, the maximum
data_exchange telegram length is loaded from XPE-E. For shorter
data_exchange telegram length select one of the possible
configurations which are defined in the GSD file or select those
arbitrarily according to the PROFIBUS-DP standard.
ð
After successful parameterization XPS-E is prepared for data exchange.
The Status/Run LED is now flashing green.
NOTICE
You can verify the parametrization and configuration telegram by
means of slave_diag.
In the following, only those parameters are described that are required for
operating the XPS-E. For the significance of the remaining PROFIBUS- DP
standard parameters please refer to the standard EN50170 and the GSD
file.
