View source for IBHNet:Technical Data IBH Link S7


The '''''IBH Link''''' is an ethernet gateway. '''''IBH Link''''' fits in a DSub-housing. It consists of a complete fieldbus master together with a 10/100 MBit/s ethernet interface which uses Auto-Negotiation to determine the speed of the network ist is connected to.


Due to the design in a D-Sub housing the '''''IBH Link''''' can be directly attached on the fieldbus-connector of a MPI-capable device. The '''''IBH Link''''' is connected to the next hub or switch by a 3m long STP-cable.


'''If the ''IBH Link S7'', ''IBH Link S5++'' or the ''IBH Link S7 Plus'' need to be connected directly to the PC, a crossed cable (Cross Over) may be required with older network cards. An ''IBH CX'', ''IBH Link S7++'' and the ''IBH Link S7++ HS'' can always be used with a normal or a crossed cable.'''


The '''''IBH Link''''' is directly supplied over its MPI interface.


The configuration takes place over ethernet. Therefore you have to start '''''IBHNet''''' on a PC which is connected to the same ethernet segment like the '''''IBH Link''.'''


A diagnosis channel to the '''''IBH Link''''' is established over a defined TCP/IP port. The configuration is stored in a flash memory inside the '''''IBH Link'''''.

For the connection of the '''''IBH Link''''' to the MPI interface of a Siemens S7 or another MPI-capable device no connection-cable is needed. The '''''IBH Link''''' is directly attached on the MPI interface of the device.


No external power supply is required, the '''''IBH Link''''' is supplied by the MPI interface.


'''ATTENTION:'''

* '''Due to its compact size, the ''IBH Link'' does not have a reverse voltage protection!'''
* '''Some PLCs may have a temporary error condition on the the MPI/Profibus for the startup period of the internal profibus chip, if the ''IBH Link'' is connected in an angular position. If the ''IBH Link'' needs to be connected to a PLC that reacts sensitive to this behaviour, the ''IBH Link'' must only be connected in powerless state of the PLC.'''
