DNP3

Application Layer Timeout

Period long enough for an entire Application Layer message to be transmitted represented in hh:mm:ss.fff format.

Enable Unsolicited

If enabled, the adapter accept unsolicited messages from an outstation that is configured to send unsolicited event data.

Enable Time Sync

If enabled, the adapter writes the current time to an outstation that indicates "NeedTime" through the internal indication bits.

Integrity Scan On Startup

If enabled, the adapter performs an integrity scan whenever the adapter or outstation is restarted.

Integrity Scan On Event Buffer Overflow

If enabled, the adapter performs an integrity scan whenever the outstation's event buffers overflow

Integrity Scan Period

Frequency of integrity scans. Set to 00:00:00 for no periodic integrity scans represented in hh:mm:ss.fff format.

Event Classes

Select Add to list of event classes that the adapter scans during an event scan. Enter [1, 2, 3] to include all event classes.

Event Scan Period

Frequency of event scans represented in hh:mm:ss.fff format..

Server Certificate Dns Name

The subject name, which is verified in the presented server certificate, from the SAN extension or in the common name field.

The server verifies that TLSChannel.ServerPublicKey is valid for this name.

Note: This is only used when TCPChannel.CertificateValidationMode is set to CASigned

Server Public Key

The file name or full path of the unencrypted PEM file containing the trusted root certificate(s) or the peer self-signed certificate.

Tls Version

Minimum TLS version allowed.

If set, valid values are “None”, “1.2” or “1.3”.

Note: If set to None, TLS encryption will not be used.

Tls Validation Mode

Valid values are CASigned and SelfSigned.

• CASigned verifies that the root certificate is one provided in the ServerPublicKey.

• SelfSigned validates that only a single certificate is present and is a direct match of the one specified in ServerPublicKey.

  If this is set to SelfSigned, the validation of the certificate chain and the end-entity certificate of TCPChannel.TlsPeerCertificate is bypassed.

Stream Id Prefix

Specifies what prefix is used for stream IDs. The naming convention is {StreamIdPrefix}{StreamId}.

Default Stream Id Pattern

Specifies the default stream ID pattern to use, such as {OutstationId},{DNPPointType}, {Index}, {Group}, and {Variation}.

An empty or null value results in the default value. {OutstationId}.{DNPPointType}.{Index}.

Link Status Request Interval

The time interval, measured in seconds, in which the adapter sends a DNP3 Link Status Request to each configured data source when operating in warm failover mode.

These periodic requests allow the adapter to confirm that TCP channels and outstations remain reachable, ensuring accurate device status reporting during failover scenarios.

Note: This parameter works only with warm failover.

Tls Client Public Key

The file name or full path of the unencrypted Privacy Enhanced Mail (PEM) file that contains the certificate the adapter presents to the peer.

Tls Client Private Key

The file name or full path of the PEM file containing the encrypted or plaintext private key corresponding to the public key in the presented certificate.

Only PKCS #8 v2 encrypted files are supported.

Tls Private Key Password

Password used to decrypt the private key file.

If the file is not encrypted, leave this field empty.
