| Type of used client (driver for OPC UA communication):
| Default Secure | Default | ||||||
| Session text identifier. Session identifier should be a unique within the client instance, making it possible to search problems faster in the client or server logs. | String | Kom process | ||||||
| The channel must be reopened before this time limit elapses. If the time is exceeded, the channel will be closed and unable to change data. | hh:mm:ss | 01:00:00 | ||||||
| Any message should be changed between client and server before this time limit elapses. If it is not sent, the sources within the session that are kept on the server are released. The primary work of this parameter is to remove the sessions that became inactive because of some unexpected reason. | mm:ss | 01:00 | ||||||
| Type of authentication used with the OPC UA server. Supported types are:
| Anonymous / Username | Anonymous | ||||||
| User name used in authentication if Authentication type = Username. | ||||||||
| Password used in authentication if Authentication type = Username. | ||||||||
| Security policy (only for Client Type = Secure; for Client Type = Default a security policy None is used):
| None Basic128Rsa15 Basic256 Basic256Sha256 | None | ||||||
| A mode of message security in OPC UA communication (only for Client Type = Secure; for Client Type = Default a mode of message security None is used):
| None Sign Sign & Encrypt | None | ||||||
| It changes the number of information about communication. We recommend enabling the Extended/Full modes only when detecting the problems and debugging the communication. The "Full + Trace (Secure only)" mode is valid only for Client Type = Secure. | Normal/Extended/Full/ Full + Trace (Secure only) | Normal | ||||||
| The parameter defines the thread(s) that will send the debug info about the communication. | Receiving/Sending/Others treads/All threads | All threads |
Note: all X509 certificates used in OPC UA communication can be found in the following subdirectories of the kom-opcua directory in the application directory:
- own - a directory with KOM process's own certificate (file cert.der). If this file does not exist, it is generated
- private - a directory with private key for the KOM process own certificate (file private.pem)
- rejected - a directory with rejected certificates
- trusted - a directory with trusted certificates (the first time a connection is established to an OPC UA server, its certificate is stored in this directory)
