Profibus-DP:
Connection
Below is a diagram of the connections of devices in Profibus-DP network.
As can be seen from the above diagram the connections for devices at either
end of the line (A) are different from the internally positioned ones (B).
Indeed, the connectors at A have inside them the termination resistances of
the line. There follow the types of connection existing within the connec-
tors.
Use the materials listed in the table below when making connection cables.
