Starting the SSI driver

Add a SSI driver WCCOAssi to the WinCC OA console and start it. How to add a manager is described in the chapter Administration of managers.

WCCOAssi [-num <managernumber>]

If a driver is not started via the WinCC OA console but via the command line, note that the right WinCC OA project is specified for the driver. This can be done by setting the appropriate environment variables or by specifying the appropriate command line options. The project can be specified via the -proj/-PROJ name option. How to specify the project when starting a driver via the command line is described in detail in the chapter administration of managers.

Each driver running simultaneously must have a unique driver number so that the data points represented in WinCC OA can be assigned to a driver (default is driver number 1). Of course the driver number given must be unique. So if you want to run several drivers simultaneously, define a unique number for the driver with the option -num as shown above.

Parameter Comment
-help returns a list of all command line options
>-version returns the version number.

-data [host name][:port number]

-event [host name][:port number]

these two options can be used to start a data or event manager that is different from the one specified in the configuration file, or to use different port numbers for communicating with the two managers.
-dbg [...]

outputs messages for internal diagnostics (-dbg 24 outputs messages relating to the low-level data stream, the TCP link,

-dbg 3 outputs incoming or outgoing messages).

-rcv [0][1][2] displays the data streams received from other managers in different levels of detail.
-snd [0][1][2] displays the data streams sent to other managers in different levels of detail.

Normally errors in the system are handled by sending error data points to the Event Manager. The command line options -log +stderr can be used to stop these data points being sent. The error messages are then output directly on stderr, and if necessary can be diverted to files in the operating system.

There might occur problems with the communication between SSI drive and the remote station, if for Windows 2000 the optional TCP Parameter "Selective Acknowledgement" is set to "ON". In this case change the registry entry SackOpts = 0 in HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/TcpIp/Parameters
