ABB Totalflow Communications and Telemetry Configuration
Key Takeaway
How to configure ABB Totalflow communication options — serial, Ethernet, radio, cellular, and satellite for remote oilfield and pipeline SCADA.
Quick Answer
Totalflow communicates via RS-232, RS-485, Ethernet, radio modem, cellular, and satellite. Configure ports in PCCU32. Communication outages do not affect measurement — Totalflow calculates and archives independently, reporting buffered data on reconnection.
Communication Options
- RS-485 serial — Multi-drop DNP3/Modbus over radio or direct wire
- Ethernet — TCP/IP for DNP3/TCP, Modbus TCP, and remote PCCU32 access
- Licensed radio — 900MHz/UHF narrowband, point-to-multipoint
- Cellular — 4G LTE modems for remote sites
- Satellite — VSAT/Iridium for extremely remote custody transfer sites
Communication Independence
Totalflow operates independently of communication status. Flow calculations and archiving continue during outages. On reconnection, SCADA masters retrieve all buffered DNP3 events and archived records with original timestamps.
For SCADA-side configuration, see SCADAPack communications for comparison.
Frequently Asked Questions
Via TCP/IP on port 10001 over Ethernet or cellular. VPN is recommended for secure remote access.
Yes. Flow calculations and archiving continue independently. Buffered data is reported to SCADA on reconnection with original timestamps.
