Communication
Interval
- Default setting is 60 seconds.
- Communication interval can be set to any value independently from data acquisition intervals.
- Connection between gateway and cloud platform is maintained to allow for quick delivery of commands. (only for intervals lower than 2 minutes)
Cellular fallback
Note
This feature applies only to gateways equipped with both:
- Ethernet port.
- 2G or 4G cellular modem.
Gateways with multiple communication interfaces can be configured to use cellular modem as:
| Cellular modem | Ethernet | Description |
|---|---|---|
| Secondary | Primary | Device will fallback to cellular modem only if ethernet connection fails. |
| Primary | Secondary | Device will fallback to ethernet if cellular modem connection is not possible. |
| Primary | Disabled | Useful in cases where ethernet interface is used for Modbus TCP only. |
| Disabled | Primary | Useful in cases where cellular modem is installed for SMS or CLIP only. |
Default setting is to to treat both interfaces equal and stick to established connection.
Protocol
Gateways communicate with the cloud platform using proprietary protocol over TCP/IP connection.
Security
Communication with cloud platform is encrypted using AES.
Compression
Data is compressed using the LZSS algorithm.
