By default, the port server log files contain information about errors that relate to the port server. You can change the registry settings so that the log files record:
- Application—General information about the port server including which port is used by the Telnet server and a record of when the port server is shutdown
- Errors—Errors that relate to the port server
- I/O—Information about the data transfer (input and output via the ports)
- Serial Ports—Information about the ports (when they are assigning, being de-assigned, and so on)
- Clients—Information about the drivers that are using the ports
- Modems—Information relating to modem sharing
- Protocol Sharing—Information about the any port sharing.
These options are stored as a bit mask in the registry. You can set the log files to record one or more of the above types of information.
To change the registry settings:
- Access and Run a Registry Editor.
- Using the Registry Editor, expand the keys to locate the PortServer key, and then select it.
The PortServer key is available in the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Schneider Electric\ClearSCADA\PortServer
- Right-click on the LogLevel registry setting for the Port Server to display a context-sensitive menu.
- Select the Modify option to display the Edit DWORD Value window.
- In the Value field, enter the number for the required type(s) of logging.
- Bit 0 corresponds to Application. For Application logging, enter 1.
- Bit 1 corresponds to Errors. For Errors logging, enter 2.
- Bit 2 corresponds to I/O. For I/O logging, enter 4.
- Bit 3 corresponds to Serial Ports. For Serial Ports logging, enter 8.
- Bit 4 corresponds to Clients. For Clients logging, enter 16.
- Bit 5 corresponds to Modems. For Modems logging, enter 32.
- Bit 7 corresponds to Protocol Sharing. For Protocol Sharing, enter 128.
If you want a combination of logging information, enter the total for both numbers. For example, if you want Errors logging, I/O logging and Modems logging, enter 38 (Errors logging is 2, I/O logging is 4 and Modems logging is 32).
We recommend that you enable Errors logging.
- Select the OK button.
- Restart the port server service to instigate the changes (see Restart the Port Server Service).
