PCCU32 Interface Overview
Key Takeaway
How to navigate the PCCU32 interface — device tree, application registers, live data monitor, archive viewer, and configuration tabs.
Quick Answer
PCCU32 organizes Totalflow configuration around applications (software modules performing specific functions) and registers (numbered data addresses for all values). The interface provides a device tree, live data monitor, archive viewer, and report generator.
Application Concept
Each Totalflow function — AGA-3 calculation, Modbus communication, DNP3 reporting, PID control — runs as a separate application. Applications have their own register sets configured through PCCU32 screens.
Register Concept
Every data point (inputs, outputs, calculated values, configuration parameters, archives) is addressed by register number. PCCU32 displays registers in organized application screens, but all data can also be accessed directly by register address for SCADA mapping.
Key Interface Areas
- Device Tree — Applications, I/O, communications, archives
- Live Data — Real-time register values with write capability
- Archive Viewer — Browse hourly, daily, and event records
- Report Viewer — Flow statements and measurement reports
- Audit Trail — Configuration change history

Frequently Asked Questions
An application is a software module running on the device that performs a specific function (AGA-3 calculation, PID control, Modbus communication). Each has its own register set configured through PCCU32.
Every data point is addressed by register number. PCCU32 displays registers in organized screens, and SCADA systems access data by register address via DNP3 or Modbus.
