Profibus DP/RS-485.
Profibus DP (Decentralized Periphery) is an open field
bus standard used in Process Industry and Factory
Automation. It is optimized for speed, efficiency, and low
connection costs and allows for multiple data senders and
receivers to be connected to an ongoing cable. Data
traffic is continuous.
To check this bustype, ScopeMeter Channel A and B are
on and DC coupled. The recommended probes are the
Fluke 10:1 probes. Connect the probe as shown below.
DATA

DATA -
DATA GND
The positive (RxD/TxD-P, DATA +) wire is usually green;
the negative (RxD/TxD-N, DATA -) wire is usually red.
Cabling and some connector examples are shown in the
adjacent figures. Please note that cables often
incorporate termination resistors at the end of the network
chain.
