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

Connection for PROFIBUS DP

9-pin Sub-D plug,
contact assignment as described in IEC 61158/EN 50170

Backplane bus

Connection through S7 backplane bus connector (only necessary for DP/PA link); non-floating

The active BM DP/PA bus modules are required for the hot swapping function

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-alone operation of the IM 153‑2 High Feature is not possible.

1 Y coupler, up to 5 DP/PA couplers or up to 64 slaves can be connected

Isolation from the higher-level DP master system

Interfaces

  • Connection for PROFIBUS DP

9-pin Sub-D plug, contact assignment as described in IEC 61158/EN 50170, Vol. 2

  • Backplane bus

Connection through S7 backplane bus connector, non-floating

Bus modules and profile rails for hot swapping are required for the hot swapping function and for a redundant PROFIBUS DP interface module.
