Operation
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 through setting 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 set by the
adapter at the time the adapter is powered on or power cycle
reset. 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
PROFIBUS communication module using the default Station
Address of 125.
Any PROFIBUS Station Address setting greater than 125 will
result in the C441 PROFIBUS communication module using
the default Station Address of 125.

PROFIBUS Status LEDs
There are three LED indicators (ON, BF, and SF) to clarify the
working state of the PROFIBUS module/network.
