Configuring network transition¶

The gateway can be used to configure a network transition to H1, MPI or PROFIBUS. The gateway enables communication between the octoplant Server and an automation device that cannot be reached directly through the TCP/IP network of the server.

Requirements¶

The gateway must be installed on a PC that can be reached through the TCP/IP network of the server.
The network transition from TCP/IP to H1, MPI or PROFIBUS requires the configuration of the [SimaticNet] section in of the configuration file VDogGateway.ini file. The gateway carries out communication via the channel defined by the access point (configured by [SimaticNet]\AccessName). For this communication channel, the software SIMATIC NET must be available (installed and licensed) with the required support for the network interfaces.

Configuration of the gateway¶

The settings for the Gateway are configured using the INI file VDogGateway.ini. The file can be found under: {Drive}:\vdoggateway\VD$A\Configuration\

Open the VDogGateway.ini file using a text editor, for example Notepad++.
Implement the desired settings. Possible settings can be found in the following table.
Save the data and close the text editor.

Sections of the VDogGateway.ini file¶

[Rfc1006]¶

This section is used to configure the network transition from TCP/IP to H1, MPI or PROFIBUS.

Key	Description	Value	Default
Enabled	Key for activating communication via RFC 1006	Y/N	Y

[TCPIP]¶

This section is used to configure the port.

Key	Description	Value	Default
Port	Key for configuring the port for communication via RFC 1006. By default, communication takes place via port 102. If this port is already occupied, another port number must be assigned to the service.	{1...65535}	102.

[SimaticNet]¶

This section is used to configure access to the SIMATIC NET PC software.

Key	Description	Value	Default
Enabled	Key for activating the interface to SIMATIC NET	Y/N	Y
AccessName	Key for configuring the access point (also called AccessPoint) via which the desired communication channel is defined in SIMATIC NET	{Name of the access point}	S7Online

Example configuration¶

[Rfc1006]
Enabled=Y
[TCPIP]
Port=65500
[SimaticNet]
Enabled=Y
AccessName=PC internal (local)

FAQ¶

Why is the gateway not starting?

The VDogGateway service communicates using the port 102 (RFC1006) by default. If this port is already used by another application (e.g. by the Siemens IEPG Helper Service, name of the service: s7oiehsx.exe ), the service should be assigned a different (unused) port number. To assign a specific port number to the VDogGateway service, the following section must be added to the VDogGateway.ini file or the TCPIP section contained in it must be changed as follows:
Path:
..\{directory where the file VDogGateway.exe is located}\VD$A\Configuration
File:
VDogGateway.ini
Section:
[TCPIP]
Key=Value:
Port={A number in the range 1..65535}
