Data sources

Manage data sources in the ENLYZE Platform.

In the ENLYZE Manufacturing Data Platform (MDP), a data source represents a virtual or physical OT device that is connected to the ENLYZE MDP via a connector to collect process data. Examples of data sources include programmable logic controllers (PLCs) such as the Siemens S7-1200, Modbus energy meters, or OPC-DA and OPC-UA servers running on industrial PCs (IPCs).

While energy meters are typically connected only via Modbus, PLCs like the Siemens S7-1200 support connections using various protocols, such as the native OMS+ (S7+) and OPC-UA.

Process data is collected from a data source by selectively reading one or more variables. There are two methods to register the available variables from a data source in the ENLYZE MDP, depending on the protocol used for the connection.

Variable Discovery

Variable Discovery is an automated process where an Edge Device assigned to the data source queries the available variables and registers them in the ENLYZE MDP.

Applicable protocols:

• S7+ (OMS+)

• PVI

• OPC-DA

• OPC-UA

• Beckhoff ADS

Manual Registration

If a data source is connected via a protocol that does not support Variable Discovery, the available variables must be registered manually. This often requires additional resources such as data sheets or project files.

Applicable protocols:

• S7 (Step 7)

• Modbus
