PROFIBUS

PROFIBUS
The network must be terminated with a resistor at the physically first and last node.
Activate the bus terminating resistor at these nodes in the bus connection plug.
Typical topologies
M Master
S Slave

Station address - example:
OFF OFF
Station address = 16 + 4 + 2 + 1 = 23
Do not set station address = 126 and station address = 127. These station addresses are invalid.
