View source for IBHLink S7++:S7-300/S7-400 WinCC flexible

It is possible to realize a connection from a WinCC flexible Runtime/Panel to a S7-200 PPI station over ethernet using an [http://www.ibhsoftec.com/IBH-Link-S7-PP-Eng IBHLink S7++] or [http://www.ibhsoftec.com/IBH-Link-S7-PP-HS-Eng IBHLink S7++ HS]as gateway.

==Example==
In the following example a configuration with WinCC flexible is shown.
The HMI station ist connected to the IBHLink S7++ via an Ethernet connection. The IBHLink S7++ itself is connected to a S7-300/S7-400 station by MPI or PROFIBUS. Bus parameters were configured by the IBHNet configuration tool.

The following addresses were chosen in the example:

IP addresses:
{| class="wikitable"
|-
! Station !! Address
|-
| HMI station || 192.168.0.194
|-
| IBHLink S7++ || 192.168.0.167
|}

MPI/DP addresses:
{| class="wikitable"
|-
! Station !! Address
|-
| IBHLink S7++ || 5
|-
| S7-300/400 station || 12
|}

Configuration:

The ethernet communication driver for S7 300/400 must be selected in WinCC flexible, since only this driver allows the selection of an extension slot on the PLC side. This setting is necessary for the selection of the MPI/DP address to use for the connection.

If you are using the WinCC flexible Runtime, please check that in the settings of the PG/PC Interface the correct driver ''TCP/IP'' for the Access Point ''S7ONLINE'' is chosen.

The configuration of the connection is now completed and you can continue with defining your Tags.
