“Upstream” network	Profibus-DP
“Downstream” network	Modbus RTU
Profibus-DP	• Transmission method: PROFIBUS DIN 19245 Part 1.
characteristics	• Nature of network: Device-oriented bus (DeviceBus).
	• Network topology: multipoint linear topology (bus) with adapted and active line
	terminations (see chapter 2.6.2 Wiring Recommendations for the Profibus-DP
	Network, page 20).
	• Physical media: single twisted pair copper cable, shielded or not, preferably a
	type A Profibus-DP cable, with the following characteristics:
	- Impedance	.......135 to 165 Ω		- Loop impedance		110 Ω/km
	(nominal value		150 Ω)	- Conductor diameter		0.64 mm
	- Capacity	< 30 nF/km		- Conductor section		> 0,34 mm²
	• Connections: 9-point SUB-D connectors, preferably (see chapter 2.6.2 Wiring
	Recommendations for the Profibus-DP Network, page 20).
	• Communication speed: 9.6, 19.2, 45.45, 93.75, 187.5, 500, 1,500 or 12,000 kbits/s.
	• Maximum network length: the length of each segment (from one line termination
	to the other) is limited and depends upon the transmission rate. Using one, two,
	or three repeaters makes it possible to put such segments end to end; one can
	thus derive the maximum total length of the network, without changing the
	maximum length of each segment.
				Maximum	Max. network length

	Up to 93.75 kbits/s			1,200 m		4,800 m
	187.5 kbits/s			1,000 m		4,000 m
	500	kbits/s		400 m		2,000 m
	1,500	kbits/s		200 m		800 m
	12,000	kbits/s		100 m		400 m
