Preferences > Basics > License

Designation

Meaning

Hardware Key

Hardware key that you entered when requested to

enter the license key. If the hardware key of this

license key matches the hardware key under this

license table, then you can use this license key on

this network management station.

License Holder

Name that you entered when requested to enter the

license key.

Registration Code

Registration code you received upon purchase of a

full version, upgrade or maintenance schedule.

You used this registration code to request the

license key.

Table 41: Entries in the license table

A full license allows you to monitor a particular number of devices in

Industrial HiVision. A full license is linked to the version of Industrial

HiVision at the time of purchase.

Note: To determine the hardware key, Industrial HiVision uses a number

of hardware components of its network management station. These

hardware components include the network interface cards. For you to be

able to replace hardware components, Industrial HiVision compares

specific combinations of the hardware components in order to determine

the hardware key.

As long as at least one of the network interface cards in the network

management station that was installed when the license key was

requested is active, Industrial HiVision detects the correct key. In this

case, Industrial HiVision requires that other hardware components are

still installed.

When Industrial HiVision detects that the management station is without

an active interface card the “Hardware Key“ field displays this message.

“The Hardware Key is not valid. It contains no network interface.” To

display the hardware key, add a network interface. You can also activate

a network interface for this purpose.

Preferences > Display > Event

 Event

This dialog gives you the option of entering initial settings for the

displaying of events.

Events in the event list (see figure 7):

 “Max. Number of Events“

Use the drop-down list to select the maximum number of events which

Industrial HiVision displays in the event list. If more events occur than

the number specified, then Industrial HiVision discards the older

events (first in, first out).

Default setting: 1000

Value range: ≤50000

 “Event Display“

You use “Show Event List and Summary“ to display/hide the event list

and the event summary in the main window.

Default setting: display.

 “Event Log to File“

With “Logging Enabled“ you can set Industrial HiVision to write every

event that occurs in the event log file. Industrial HiVision writes the

event log file in the language of the operating system.

You will find the HiVisionEvents0.csv event log file in the installation

directory of Industrial HiVision under \log\events.

If the HiVisionEvents0.csv file exceeds a size of 1 MB, then

Industrial HiVision renames the HiVisionEvents0.csv file as

HiVisionEvents1.csv. Industrial HiVision writes new events in the

new HiVisionEvents0.csv file.

If the size of the HiVisionEvents0.log file exceeds 1 MB again,

Industrial HiVision renames the files:

- the HiVisionEvents1.csv file as HiVisionEvents2.csv

- the HiVisionEvents0.csv file as HiVisionEvents1.csv

- etc.

Industrial HiVision can write up to 1000 log files. If other events occur,

Industrial HiVision overwrites the HiVisionEvents999.csv file in

accordance with the scheme described above.

 “Logfile path“

As an alternative to the installation directory, this line gives you the

option of selecting a path on which Industrial HiVision writes the event

log file.

Note: Delays or interruptions while writing to a network drive can block

the Industrial HiVision service.

Note: Delays and interruptions in the network can result in gaps in the

content of the event log file.

Note: As the service writes the log file, the local system account

requires write permission for this directory.

 “Status Change Caused by Status Propagation“

A status change for a property of a component/folder is an event which

Industrial HiVision can display as an entry in the event list.

Use the drop-down list to select the events that Industrial HiVision

displays:

“No Event“, if you only want to display the status changes on the

lowest level as an entry. The status changes which are propagated

upwards from the lowest level are hidden by Industrial HiVision as

an event entry.

“Info Event“, if you want Industrial HiVision to display the status

changes as entries in the event list. The event entries caused by a

propagated status change are assigned the type “Info” (see on

page 90 “Number of events”).

“Similar Event“, if you want Industrial HiVision to display the status

changes as entries in the event list.

The event entries caused by a propagated status change are

assigned the type corresponding to the propagated status change

on this level.

Default setting: No event.

 “Source“

For an event that relates to a device, Industrial HiVision adds to the

event list the device name with the location that you entered in the

“Location“ device property.

 Services Access

The “Services Access“ dialog lets you to activate and deactivate various

methods of accessing network management from another computer.

When a firewall separates your Industrial HiVision services from a client,

add a rule to the firewall to forward data between the services and client.

See “Using Industrial HiVision with Firewalls” on page 62.

 “Web Server“

This service allows you to access your network management server

using a Web browser using another computer. The address of the

Web server is:

protocol://IP address of the network management station:port number,

for example

http://10.0.1.159:11194

When setting up a secure connection using HTTPS, Industrial HiVision

uses a Hirschmann certificate that classifies your browser as invalid. If

you want to use this service, then you trust this connection, add an

exception to your browser. Save the exception.

If you wish to specify a different value that Industrial HiVision uses to

connect to the “Web Server“, then unmark the “Use Default Values“

checkbox. Enter the desired value in the “Port“ field. If you mark the

other computers to have access to the local Industrial HiVision service.

If you permit “Services Access“, then the local interface connects

using the network connection, as an alternative to the internal IP

address 127.0.0.1. The local interface connects the same way as the

interface of the external computer. A result of this is that the internal

interface also loses the connection to the service if the network

connection is interrupted.

The “Port“ field displays the port on which Industrial HiVision

interfaces, running on other computers, can access the local Industrial

HiVision service.

Note: Starting with Industrial HiVision release 8.0, you can change the

value of the Project Data Server > Port field.

If you use this management station as a subdomain, then the dialog

gives you the option to type in the password for access to the

subdomain interface. See “Connect subdomains to superdomains” on

page 56.

“Superdomain“

When a secured connection is established, Industrial HiVision lets you

select the process that the superdomain uses to handle certificates

provided by the subdomain:

 “Accept any subdomain certificate“

This method permits the superdomain to accept the certificate

provided by the subdomain without verification. The certificate is

not added to the trust store and an event is created with the

fingerprint of the subdomain in the message.

Default setting: marked

 “Accept any subdomain certificate and store as trusted“

This method permits the superdomain to accept the certificate

provided by the subdomain without verification. The certificate is

added to the trust store and it is used for future connections. An

event is created which records the fact that the fingerprint of the

subdomain is added to the trust store.

Default setting: unmarked

 “Verify subdomain certificate against trusted certificates“

This method is used to verify that the certificate provided by the

subdomain is added to the trust store.

If the certificate is not in the trust store, then the connection is

rejected. An error event is created with the fingerprint of the

subdomain in the message.

Default setting: unmarked
