Controlstar Integrates Intrinsic Safe (Ex ib) and Flameproof (Ex d) I/O using Profibus DP-V1

These two I/O systems can coexist with the Controlstar’s® own CAN based I/O. Digital measurements and control variables from Hart instrumentation are also supported through the Turck Banner ‘Excom’ I/O system. The I/O is configured using the ‘Fusion’ tool, a fully integrated control, SCADA and telemetry system to be built using this single tool.
Profibus DP-V1 directly from the Controlstar®, this supports Intrinsically Safe, Explosion proof, and PA equipment.

Personnel with no previous programming experience can develop the control algorithms. When the system is ‘live’ the control algorithm drawings are available via the SCADA showing the real time state of the logic, and the measured and calculated variables. These real time control algorithms together with the standard SCADA trends, events and alarms provide diagnostic support that is unambiguous and easy to understand.

The 10.000 PSI separation process is controlled by a single Controlstar®; with the unit providing flow measurement using AGA8 and an online Gas Chromatograph.

The Controlstar® AGA8 Function block uses the ‘Detailed Characterization Method’; it has been validated against the AGA standard. The operator interface allows either manual entry of the gas fractions, or the unit can collect ‘live’ data directly from a Gas Chromatograph, at present a Modbus RTU interface is available, the system supports the range of Daniel Chromatographs. The AGA3 Function block supports the Rosemount Annubar flow element.
