Device Configuration

For each device listed in the device view (on the left side of the main window), you can manually configure scan parameters, to fine tune data acquisition. You can easily identify which devices are active (unplugged icon) or inactive (plugged icon) for real-time monitoring.

To manually add a device, use the "Add Device" button on the toolbar, or right-click any empty space on the device view and choose "Add Device" from the context menu.

Device Configuration Dialog

You can customize the following device settings:

	IP Address: Configured IP address for the specified device.
	Device Description: A short description of this device.
	Community: SNMP community for OID reads (acts like a SNMP device password).
	Item Name Delimiter: The separator character to use in the fully qualified OPC name.
	SNMP Version: SNMP procotol version to be used for data aquisition.
	Read Timeout: Amount of time (in milliseconds) to wait for a response from the device.
	Group OID Reads: Number of SNMP variables to be read in the same SNMP call.
	Refresh Rate: Device refresh rate in milliseconds.
	Trap Hold Time: Amount of time to hold before resetting a trap item.
	Scan Active: Defines whether the device will be monitored or not.

Some device settings are critical. This means that they may be changed only for optimization purposes. Also some devices do not support scanning too many variables in the same SNMP call, so you might have to change the "Group OID Reads" configuration to use such devices.

After editing or adding the device, just click on the "OK" button to close the Device Settings dialog and update the device settings. If you want to discard all changes, just click the "Cancel" button to close the Device Configuration dialog.
