App Timeout - ms

Maximum time that the Application layer waits for a full response from the Data Link layer. If receiving a request is ongoing in the Data Link layer, this time is extended automatically up until the end of the reception by the Data Link channel. The default value of this option depends on the communication rate used, but it is recommended that this value be equal to or greater than the time-out value of IOKit library, defined on the Setup tab. This time-out value of IOKit library represents the time-out byte by byte of a message, while the value of this option represents one or more full messages from the Data Link layer

App Read Retries

Number of communication retries performed by the Application layer in case of a reading error. The default value of this option is 0 (zero)

App Write Retries

Number of communication retries performed by the Application layer in case of a writing error. The default value of this option is 0 (zero)

Master Address

Indicates the address of the Master station

Control Relay Off Time - ms

When sending Control Relay Commands with individual Tags, this option indicates the normal time for Turned Off or off-time for Pulse On/Off or Latch On/Off commands

Control Relay On Time - ms

When sending Control Relay Commands with individual Tags, this option indicates the normal time for Turned On or off-time for Pulse On/Off or Latch On/Off commands

Default Slave Address

Default DNP address of a device, used when the N1 parameter of each Tag is configured in 0 (zero)

Delay Between Messages

Delay time applied between each message sent by this Driver, in milliseconds

Error Count for Inactive State

Indicates how many consecutive errors this Driver must consider to set a device into the Inactive status. This Driver tries to communicate again with that device during the next scan of any Tag from the same address or only during the time informed in the Demotion Time option, if that feature is used

Extra Sync Offset +/- ms

Time, positive or negative, added to syncing commands

Control Block Qualifier

When performing a control-block writing command or a digital output command, such as Direct Operate, Select, or Operate, among others, users must send a qualifier that may vary from device to device. Possible values in this option are 39, or 27h, for the range field with 1 (one) byte and prefixed object with 2 (two) bytes, or 40, or 28h, for the range field with 2 (two) bytes and prefixed object with 2 (two) bytes. Please check the device profile of a device for the correct qualifier

IIN Qualifier

When a Slave device informs a restart, this Driver performs a writing to the Internal Indications Object, informing the acknowledgment of an event. Use this option to inform the qualifier, available on the Slave Device Profile document of a Slave device. The most common values are 0: 1 (one) starting or ending index byte or 1: 2 (two) starting or ending index byte

Perform Class 0 Integrity on Startup

Performs a Class 0 request when starting this Driver, which retrieves the whole database of a device to update all Tags. Event Tags, in this case, have the TimeStamp property as the time of data reception and the Quality property is equal to 216

Enable Unsolicited on Startup

Indicates whether this Driver must send a command to enable unsolicited messages when starting a communication

Initialize Upon Receiving Device Restart

Indicates whether this Driver must send initialization commands of a device (Reset Link, Class 0, and Enable Unsolicited, if enabled) when receiving a message that a device was restarted

Scan for Events every (ms)

Sends a command to read Classes 1 (one), 2 (two), or 3 (three) to check whether there are events in a device. Indicate the time interval that a command repeats

Perform Class 0 Integrity every (ms)

Performs a Class 0 request cyclically, aiming only to check whether this Driver's database is equal to a device's database. The default time is 10 or 15 minutes
