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

Connecting and Disconnecting a C441
PROFIBUS Module from the C440, C441, S611,
S811+ or as a Stand-Alone I/O Module
A C441 PROFIBUS module will work with whatever device it
is connected to out-of-box, C440, C441, S611, S811+ or as a
stand-alone I/O module.
If a C441 PROFIBUS module has previously been connected
to one device type and then needs to be connected to
another device type, the following procedure must be
performed.
1.
Disconnect the C441 PROFIBUS module from the
existing device.
2.
Set the DIP switches on the C441 PROFIBUS module to
a value of three per
Figure 13
.
3.
Toggle the top switch shown in
Figure 13
5 times
(off-on-off is one cycle). A reset will occur after the fifth
cycle indicated by all LEDs turning ON, then OFF again.
Turn power off to the module.
4.
Connect the C441 PROFIBUS module to the new device
or use it as a stand-alone I/O module. When it is
powered up again, it will begin working with the new
device or as a stand-alone I/O module.
