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
| Data Capturing | Data Processing | IT/Cloud Interface | (S)ingle / (M)ulti network |
|---|
| OPC UA Client | Node RED | Node-RED | M |
2. Data acquisition via Edge Server
| Data Capturing | Data Processing | IT/Cloud Interface | (S)ingle / (M)ulti network |
|---|
| Edge Server | - | OPC UA Server | S |
| Edge Server | Node-RED (via OPC UA Client or RESTful API) | Node-RED | S |
| Edge Server | - | RESTful API | S |
3. Data acquisition via PLC access
| Data Capturing | Data Processing | IT/Cloud Interface | (S)ingle / (M)ulti network |
|---|
| SIMANTIC S7-300/1200/1500 | Node-RED | Node-RED | M |
4. Data acquisition via IO Device (slave) integration
| Data Capturing | Data Processing | IT/Cloud Interface | (S)ingle / (M)ulti network |
|---|
| IO Device (slave mode) | Node-RED | Node-RED | S |
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
| Data Capturing | Data Processing | IT/Cloud Interface | (S)ingle / (M)ulti network |
|---|
| Passive Fieldbus Integration | Custom Docker Container | Custom Application Interface | S |
| Passive Fieldbus Integration | Node-RED | Node-RED | S |
| Passive Fieldbus Integration | - | OPC UA Server | S |
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.
6. Data acquisition via MQTT
| Data Capturing | Data Processing | IT/Cloud Interface | (S)ingle / (M)ulti network |
|---|
| MQTT | Node-RED | Node-RED | M |
