Parameterization of the Profibus-DP-Slave
The parameters needed by the gateway are coded in the user-parameters. They con-
tain one byte to select the professional mode, the AS-i configuration data and AS-i pa-
rameters for all the AS-i slaves and the statements about user memory bytes to be
read and to be written.
20 user memory
hex
statement
(4 bytes)
The fields user memory statement and AS-i configuration data and AS-i (startup-) pa-
rameters are optional. However the order of the fields is stipulated. Therefore the fol-
lowing four combinations are possible:
1.
20
hex
2.
20 user memory
hex
statement
(4 bytes)
3.
20 user memory
hex
statement
(4 bytes)
4.
20 user memory
hex
statement
(4 bytes)
In the cases 1 and 2 no AS-i configuration data and AS-i (startup-) parameters are
stated in the user parameter telegram. In these cases the AS-i configurations stored
in the EEPROM of the AS-i/PROFIBUS Gateway are used. So AS-i can be projected
using the AS-i Control Tools or the push buttons on the device before Profibus is put
into operation.
The fields of the Profibus parameter telegram are constructed as follows:
• user memory statement (4 bytes)
Byte 0: Start address of the user memory window in the input data telegram
Byte 1: Length of the user memory window in the input data telegram
Subject to reasonable modifications due to technical advances.
