Configuring the gateway
Via the gateway a network transition to H1, MPI or PROFIBUS can be configured. The gateway enables communication between the octoplant server and an automation device that cannot be accessed directly via the TCP/IP network of the octoplant server.
Requirements:
- The gateway needs to be installed on a PC that can be accessed via the server’s TCP/IP network
- For the gateway from TCP/IP to H1, MPI or PROFIBUS, the section [SimaticNet] must be configured in the configuration file VDogGateway.ini. The gateway carries out communication through the channel defined by the access point (configured via [SimaticNet]\AccessName). For this communication channel, the software SIMATIC NET must be present (installed and licensed) along with the required support for the network interfaces.
Configuring a Gateway
The settings for the gateway are configured via the INI file VDogGateway.ini.
The file can be found under: <Drive:>\vdoggateway\VD$A\Configuration\
- Open the file VDogGateway.inii via a text editor, for example using Notepad++.
-
Implement the settings that you wish to have. Possible settings can be found in the following table.
-
Save the data and close the text editor.
| Section | Key | Value |

[Rfc1006] This section is used to configure the gateway from TCP/IP to H1, MPI or PROFIBUS |
Enabled Key for activating communication via RFC 1006 |
Y/N Default: Y Example: Enabled=Y |
|
[TCPIP] This section is used to configure the port |
Port Key for configuring the port for communication via RFC 1006 |
{1...65535} Default: 102

[SimaticNet] This section is used to configure access to the SIMATIC NET PC software |
Enabled Key for activating the interface to SIMATIC NET |
Y/N Default: Y Example: Enabled=N |
|
AccessName Key for configuring the access point, via which the desired communication channel is defined in SIMATIC NET |
{Name of access point} Default: S7Online Example: AccessName=PC internal (local) |
Port 102 is used for communication by default. If this port is already in use, then the service must be assigned a different port number.

octoplantGateway cannot be started. What could be the reason?
The service VDogGateway communicates by default via port 102 (RFC1006). If this port is already being used by another application (for example, by Siemens IEPG Helper Service, name of service: s7oiehsx.exe), a different (unused) port number should be assigned to the service.
To assign a specific port number to the service VDogGateway, the section TCPIP has to be added to the file VDogGateway.ini or the section "TCPIP" already contained by this file has to be modified as follows:
