2.3 Parameterisation
The parameterisation data of XPS/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).
1. For initialisation of XPS/XPS-E send a
set_prm telegram. For this
purpose, use the parameters for PROFIBUS-DP and the serial interface
described in chapter 2.4.
2. Check the parameterisation with
slave_diag.
3. Then use the command
chk_cfg to configure the XPS/XPS-E. Prior to
that, the configuration can be read with the command
get_cfg from
XPS/XPS-E. If
chk_cfg is executed directly after the initialisation, the
maximum
data_exchange telegram length is loaded from XPS/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.
After successful parameterisation XPS/XPS-E is prepared for data exchange.
The Status/Run LED is now flashing green.
You can verify the parameterisation and configuration telegram by means of
slave_diag.
In the following, only those parameters are described that are required for
operating the XPS/XPS-E. For the significance of the remaining PROFIBUS-
DP standard parameters please refer to the standard EN50170 and the GSD
file.
