Communication

PROFIBUS PA

Routers: DP/PA link and DP/PA coupler

■Technical specifications

DP/PA coupler

Connection for PROFIBUS PA

• DP/PA coupler Ex [i]	2 terminals of a 4-pole screw-type
	terminal, integral terminating
	resistor
• DP/PA coupler FDC 157-0	4-pole screw-type terminal for
	connection and looping through,
	selectable terminating resistor

IM 153-2 High Feature (for extended temperature range)

Function	Linking of PROFIBUS DP
	(9.6 kbit/s to 12 Mbit/s, slave
	functionality) and PROFIBUS PA
	with support of the "Configuration
	in Run" function
	The DP/PA link function is only
	implemented by extending the
	IM 153-2 High Feature with one or
	more DP/PA couplers. Stand-

	IEC 61158/EN 50170, Vol. 2
• Backplane bus	Connection through S7 back-
	plane bus connector, non-floating
	Bus modules and profile rails for
	hot swapping are required for the
	hot swapping function and for a
