TotalFlow Application Suite (TAS) — Custom Programming on ABB Totalflow XRC
Key Takeaway
How to use TAS to create custom control programs on ABB Totalflow XRC and G5 — function block diagram, ladder logic, PID control, and field automation.
Quick Answer
TAS is ABB's programming environment for adding custom control logic to Totalflow XRC and G5 devices. TAS programs can automate field equipment, implement PID control, and coordinate multi-device operations — all running locally on the Totalflow hardware alongside flow measurement.
TAS vs PCCU32
PCCU32 configures built-in applications (AGA calculations, communications). TAS creates custom applications using function block and ladder logic programming for automation beyond standard measurement functions.
Programming
- Function Block Diagram — visual block-based programming
- Ladder Logic — relay-style discrete control
- Built-in blocks: PID, timers, counters, math, logic, communication
Examples
- Compressor station control logic with interlock and staging
- Separator level control with PID and pump-off controller
- Multi-well pad valve sequencing
TAS is supported on XRC and G5 only — XFC is a dedicated flow computer without TAS capability. For cross-platform comparison, see Allen-Bradley FBD and SCADAPack structured text.
Frequently Asked Questions
TAS adds custom control logic to Totalflow XRC and G5 for field equipment automation, PID control, and multi-device coordination beyond standard flow measurement.
No. TAS is for XRC and G5 platforms. XFC is a dedicated flow computer without custom programming capability.
