Data Acquisition, Data Processing and IT/Cloud interfaces

The tables below illustrates the interaction between data acquisition, data processing and data provisioning for IT/Cloud
applications with a netIOT Edge Gateway. Some data acquisition modules can be used multiple times in a single gateway
to manage connections to multiple devices, also if they attached to different shop floor networks. This capability is called
here as single or multi network / device.

1. Data acquisition via OPC UA Client

4. Data acquisition via IO Device (slave) integration

The combination of IO device (slave mode) and Passive Fieldbus Integration is not supported, because both capturing modes using
the same industrial ethernet interface. Otherwise, multiple capturing options can be combined.

5. Data acquisition via Passive Fieldbus integration
