Requirements:<br>
- SIMATIC Manager<br>
- IBH Link S7++ / HS with Firmware >= 2.142<br>
- CPU with MPI or PROFIBUS Interface<br>
- CPU with Ethernet onboard or Ethernet CP. The Interface must support S7 connections. It can be checked within the hardware 
properties: S7 connection active ('''Server''' means passive).<br>

Within NetPro the CPU must be connected with the Ethernet. An unspecified connection needs to be created:<br>
[[Image:EthernetMPIS7connection.png]]<br>

To access several CPUs accordingly, several S7 connections need to be configured. The connection ID is relevant for the call of the FBs/SFBs. If the amount of CPUs exceeds the amount of possible S7 connections, Ethernet to PROFIBUS via PROFIBUS CP (Multiplexing) can be chosen.<br>

Within the properties of the S7 connection the IP address of the IBH Links must be entered:<br>
[[Image:EthernetMPIS7connection2.png]]<br>

Within the Address Details enter the MPI address of the destination CPU. <br>
[[Image:EthernetMPIS7connection3.png]]<br>

The communication will be established usings the blocks FB14/FB15. There are different FB14/FB15 available. Depending if a CPU with onboard Ethernet or a CPU with Ethernet CP is used, the correct set of blocks must be chosen, otherwise there will be no data exchange.<br>
CPU with onboard Ethernet = Standard Library<br>
CPU with Ethernet CP = SIMATIC_NET_CP<br>
[[Image:FB14.png]]<br>

Sample:<br>
      CALL  "GET" , DB14
       REQ   :=M0.0                     //Start reading with positive edge
       ID    :=W#16#1                   //S7 connection ID configured within NetPro
       NDR   :=M0.1                     //Job status 
       ERROR :=M0.2                     //ERROR flag
       STATUS:=MW2                      //STATUS infomation(Siemens documentation)
       ADDR_1:=P#M 10.0 BYTE 20         //Source address connected CPU
       RD_1  :=P#M 10.0 BYTE 20         //Destination address local CPU

Depending on the type of CPU the correct set of blocks, FB14/15 or SFB14/15 must be chosen. The final step is to tranfer the S7 program and the system data to the CPU.

Within the properties of the S7 connection the IP address of the IBH Links must be entered:<br>

Establish connection via FB/SFB 15 (PUT)<br>
To establish a connection over a PROFIBUS-CP with an IBH Link S7++, more connection information is required, than NetPro permits to enter. For this reason the IBH Link S7++ can be set into the projected mode. That mode permits sending the required connection information with a call to the "PUT" block as a data structure. To set this mode, only a special ID must be entered in NetPro.

Create OB1: <br>
Within the first network the SFB15 is called to handover the parameters. Within the second network the SFB15 for the data exchange is called.<br>

Requirements<br>
- SIMATIC Manager or '''[http://www.ibhsoftec.com/S7W-Eng S7 for Windows®]''' from IBHsoftec<br>
- 2 x IBH Link S7++/IBH Link S7++ HS with Firmware >= 2.142<br>
- The operating system of the CPU must contain the blocks XPUT and XGET (SFC67, SFC68). 
The information, whether the CPU contains these blocks can be gathered from the Siemens CPU documentation. 

For this type of connection, a projected configuration with NetPro is not necessary. Within the PLC program, the blocks XPUT/XGET are called to establish a connection from one IBH Link S7 to the next IBH Link. For very comfortable configuration of the communication parameters, the blocks XPUT_IBH and XGET_IBH (developed by IBHsoftec) are available and can be found within the sample.<br>

==Connection via IBH Link Mode: Configuration via NetPro ==

Requirements<br>
- SIMATIC Manager 
- IBH Link S7++/IBH Link S7++ HS with Firmware >= 2.142<br>
- CPU with MPI Interface<br>
- Interface has to support S7 connections<br>

'''Download: [http://download.ibhsoftec.com/german/Beispiele/Ethernet_PROFIBUS_eng.zip STEP®7 Smaple: Cennction via IBH Link in prjoected mode]''' 

This kind of connection offers the possibility to exchange very fast a large amount of data - up to 64K. For the communication the standard blocks FB/SFB 8/9  (USEND / URCV) and FB/SFB 12/13 (BSEND / BRCV)are used.<br>

Routing-Modus muss in IBHLink S7++ aktiviert sein. This mode is available beginning with firmware version 2.142 . In diesem Modus sind keine unprojektierte Verbindungen über RFC1006 mehr möglich! Verbindungen über den IBHNet-Treiber funktionieren weiterhin.

[[Datei:IBH Link.png]]<br>

The IBHLink S7++ will be configured as a station within NetPro.<br>
[[Datei:IBH Link als Station.png]]<br>
The following station must be selected:<br>
MLFB: 6ES7 412-2EK06-0AB0 V6.0  Rack 0, Slot 2<br>
MPI/PROFIBUS address of the IBHLink S7++<br>
IP Address of the IBHLink S7++<br>

Configuration of the Station within Hardwarekonfigurator:<br>
[[Datei:IBH_Link_als_Station_HWK.png]]<br>

In NetPro müssen neben der IBH Link Station auch alle CPUs angelegt werden, mit denen kommuniziert werden soll. Die S7-Verbindung wird von der tatsächlichen CPU über Ethernet zur IBH Link Station aufgebaut. Hierbei ist die tatsächliche CPU der aktive Teilnehmer.<br>
[[Datei:Verbindung1.png]]<br>

[[Datei:Verbindung1Parameter.png]]<br>

Die Partner-Verbindungsresource wird automatisch vergeben und ist für den nächsten Schritt relevant.<br>

[[Datei:Verbindung1Details.png]]<br>

Die IBH Link Station baut nun eine S7-Verbindung über Profibus zur zweiten tatsächlichen CPU auf. Hierbei ist die IBH Link Station der aktive Teilnehmer. Als lokale Verbindungs-ID wird hier nun die im vorherigen Schritt automatisch zugewiesene Verbindungsresource (im Beispiel: 10) angegeben.<br>

[[Datei:Verbindung2px800.png]]<br>

Der Verbindungsstatus kann direkt in NetPro angezeigt werden:<br>

[[Datei:Verbindungsstatus aktivieren.png]]<br>

Mit dieser Verbindungsvariante sind komplexe Vernetzungen möglich:<br>

[[Image:ConnectionMulti.png]]<br>

For the connection to an IBH Link S5++ no summy CPU needs to be cnfigured within NetPro. it es neough to cnfigreu an , unspezifizierte S7-Verbindung über Ethernet einzurichten. In this case the partner IP address is the IP address of the IBH Link S5++. For communication the blocks PUT/GET are chosen- SFB14/15.<br>
