Asset links

Asset links are Linux applications installed on the same device as the Asset Gateway software and act as a translator from vendor-specific, proprietary protocols to a standardized API. Each Asset link supports a specific protocol and a range of OT devices that can be discovered and identified.

If you want to create your own Asset link, see Asset Link SDK

Additional Information

Default IP Scanner

The Default IP Scanner is included in the Asset Gateway App by default as an edge app.

Supported Attributes:

• Hostname
• IP Address
• MAC Address
• Vendor

Asset Link SNMP

The Asset Link SNMP can be obtained from the Industrial Edge Marketplace.

Supported Attributes:

• Hostname
• IP address
• MAC address
• Asset name
• Vendor
• Article number
• Serial number
• Software version

SIMATIC Automation Tool

The SIMATIC Automation Tool can be obtained from the Industrial Edge Marketplace.

Supported Attributes:

• Hostname
• MAC- and IP-addresses and their relation
• ID Link
• Vendor
• Article number
• Serial number
• Software version
• Hardware version
• Station number
• Slot number, Slot name, Subslot
• Asset capabilities like support of firmware update or backup functionality
• Connected submodules' data
• Connected periphery's data

Please refer to the separate Documentation for further information and use cases for the SIMATIC Automation Tool application.

Supported Discovery Attributes:

By default, SIMATIC Automation Tool performs a discovery starting with Layer 2 based protocol to discover all assets in a network and, if the asset supports it, continuing with the appropriate Layer 3 based protocol to identify details of the discovered asset. This behavior can be adapted using discovery filters and options.

Only discover assets in a specified IP Range

• Type: DiscoveryFilter, optional, but required if DiscoveryStrategy L3 is provided
• Key: IPRange
• Operator: EQUAL
• Value: IpStart-IpEnd, e.g. 192.168.1.1-192.168.1.20

Perform only a Layer 3 protocols based scan, do not try to discover using Layer 2 to support routed environments. Condition: IPRange Filter must be provided

• Type: DiscoveryOption, optional
• Key: DiscoveryStrategy
• Operator: EQUAL
• Value: L3

Example:

{
   "discoveryFilters":[
        {
            "key":"IPRange",
            "comparisonOperator":"EQUAL",
            "value":"192.168.1.1-192.168.1.250"
        }
   ],
   "discoveryOptions":[
        {
            "key":"DiscoveryStrategy",
            "comparisonOperator":"EQUAL",
            "value":"L3"
         }
   ]
}

Limitations:

• IPRange supports up to Class C networks, e.g. 192.168.1.1-192.168.1.254
• Layer 3 discovery option currently has limitations for discoverable device types. A broader range of supported device types is planned for an upcoming release.
