View source for IBHNet:RFC1006 Communication IBH Link S7++/S7++HS



PC-based visualization systems can be coupled by the '''''IBH Link S7++ / S7++ HS''''' to an S7 PLC without the IBHNet driver in order to read and write data.


The '''''IBH Link S7 / S7 Plus''''' needs an additional tool for the RFC1006 communication. For details see chapter &quot;RFC1006 Communication IBH Link S7 / S7 Plus&quot;.


RFC1006 uses a rack and a slot number for addressing. These are directly converted to the MPI address. In order to access MPI address 2 you need to use the value 0 for the rack number and 2 for the slot number on the side of RFC1006, for precise assignment see the table below. Some visualization software needs the TSAP. The assignment is listed in the following table:

{| class="wikitable"
!MPI !! Rack !! Slot !! TSAP
