Node Address; Network Data Rate - Leroy-Somer digitax st User Manual

5.4

Node address

Table 5.2 PROFIBUS-DP
Pr MM.03
Every node on a PROFIBUS-DP network must be given a unique network node
address. To activate a change in the node address value the SM-PROFIBUS DP-V1
must be re-initialized (Pr MM.32 = ON). This parameter is also available in menu 0 on
the Digidrive SK (Pr 00.52). Addresses 0 and 126 are reserved for system use.
5.5

Network data rate

Table 5.3 PROFIBUS-DP
Pr MM.04
The SM-PROFIBUS DP-V1 will automatically detect the PROFIBUS-DP network data
rate and synchronize to it. Pr MM.04 will indicate the data rate that has been detected
by the SM-PROFIBUS DP-V1. This parameter is also available in menu 0 on the
Digidrive SK (Pr 00.53).
A value of -1 indicates that the SM-PROFIBUS DP-V1 has not detected any activity on
the PROFIBUS-DP network, and is waiting for the master controller to start
communicating.
The PROFIBUS-DP data rate parameter can be changed, but this will not affect the data
NOTE
rate at which the SM-PROFIBUS DP-V1 communicates. The data rate display will be
updated when SM-PROFIBUS DP-V1 is re-initialized.
