Setting the PROFIBUS Address
PROFIBUS Address
The PROFIBUS address is set using the DIP switches
located on the top of the C441 communication adapter. The
address can only be set with the hardware DIP switches. The
address is in binary with the major units numbered to the
right of the switch on the label. Adding up the major units set
to ON will provide the address of the adapter on the
PROFIBUS network.
Notice
The address specified in the switches is only used by the
adapter at the time the adapter is powered on. Changing
these switches during operation will have no affect until the
next power cycle or reset.
Notice
A PROFIBUS address setting of 0 will result in the C441
using the default Station Address of 125. Any PROFIBUS
Station Address setting greater than 125 will result in the
C441 using the default Station Address of 125.
