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 SI-PROFIBUS must be
reset (Pr S.01.002 or MM.007 = On). Addresses 0 and 126 are reserved for system use.
The SI-PROFIBUS will automatically detect the PROFIBUS-DP network data rate and
synchronize to it. Pr S.01.005 will indicate the data rate that has been detected by the
SI-PROFIBUS.
A value of 0 indicates that the SI-PROFIBUS 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
rate at which the SI-PROFIBUS communicates. The data rate display will be updated
when the SI-PROFIBUS is reset.
