Lenze 2131IB - Manual (Page 27)

Parameter setting
6-4 BA2131EN
The following table shows the assignment of the addresses:
PROFIBUS-DP station address Mapping to code C0009 LECOM unit address
1-2 No (master addresses)
3-99 Yes (3-99)
100-125 Yes (C0009= 2)
126 (Lenze setting ) Yes (C0009= 1 )
6.1.5 Baud rate
Baud-rate settings are not required. The 2131 fieldbus module is automatically adjusted to the baud
rate of the master.
6.1.6 Master settings
The master needs a unit-description file (unit master-data file) for operation with PROFIBUS-DP. The
diskette provides the following files:
File name Meaning
L_AR00AA.GSD Unit master-data file to DIN 19245 T3
LE00AATD.200 Controller master data file (type file) for Simatic-S5 COM-ET200 V4.X (IM308B)
LE00AAAX.200 Controller master data file (type data) for Simatic-S5 COM-ET200 V5.X (IM308C)
You also have to set:
Function Setting (depends on the master type)
Baud rate The 2131 module is equipped with an automatic baud-rate detection
Communication profile PROFIBUS-DP DIN E 19245 T3
Slave-station address 126 (Lenze setting)
Value the same as in controller parameter C0009 (see chapter 6.1.4 “Bus
address/station address“).
DP-configuration data (configuration) see chapter 6.2
PNO-identification number 00AA
hex
DP user-data length see chapter 6.2
6.2 PROFIBUS-DP configuration
The PROFIBUS-DP user data length is determined during the DP initialization phase (configuration).
You can select from 4 fixed lengths.
The user data lengths for input data and output data must be the same.
For simplification we use the following abbreviations:
l PIW:
Process input word (process data from the controller to the master)
l POW:
Process output word (process data from the master to the controller)
The 4 selectable user data lengths are:
l 2 words process data; label 71
hex
(113)
PIW/POW 1 PIW/POW 2
Byte 1 Byte 2 Byte 3 Byte 4
