Customer Situations

“Our DCS/BPCS System is currently being

used to show both control and safety-

related alarms. We’d like to isolate our

safety system process alarms from the

DCS control system alarms.”

“We’d like to implement a better bypass

control strategy for our safety-layer field

instrumentation devices when we have to

do maintenance. We need a better way of

tracking when bypasses are enabled and

removed.”


Customer Situations

“Our hardwired annunciator panels are

aging and becoming unreliable. We’d like

to move to an HMI-style of interface, but

need for it to be easy to maintain and

change as necessary.”

• A real-time situational awareness

solution based on software tools

developed for use with Triconex Logic

Solvers for Operators and

Maintenance Engineers to monitor

and respond to critical process

alarms.

• Provide Clients with a means to

perform and manage SIF Bypass

Management for critical situations and

plant maintenance activities.

Solution Detail: Small Application Example


Solution Detail: Large Application Example

• A TÜV approved SIL3 flexible & customizable HMI-based solution designed to meet the ANSI/ISA-18.1

Annunciator Sequence and Specifications Standard to display the status of critical process alarms.

(normal, alarm, acknowledged alarm, return to normal, & acknowledged return to normal)

• Independent solution to the DCS/BPCS thus providing isolation from general process operation alarms and

maintenance actions.

– reducing potential Human error situations that could impact Plant profitability.

• Embedded automatic audit trail maintains a log of all User actions. (Log On/Off, Alarm actions, Bypass

actions, First Out actions, Entering Comments/Notes)

• Replacement for costly traditional hard-wired alarm annunciator panels which are difficult to maintain and

modify as the Plant operational requirements change. Lower overall cost of ownership.

• Reduction in the Logic Solver System Architecture and potential energy savings. (elimination of external

lamps & annunciators)


Value Delivered


Summary

• World’s First TÜV certified software based Alarm & Bypass

Management Operator Interface system.

• Approved by TÜV Rheinland for use in IEC 61511 SIL1-SIL3

applications.

• Designed to meet the ANSI/ISA-18.1 Annunciator Sequence and

Specifications Standard.

• Flexible and less costly than traditional process alarm

annunciator panels (less hardware, energy efficient, reduced

annual maintenance expenditures, easily modified).

• Engineered to work with Version 10.x and 11.x Tricon, Version

2.x and 3.x Trident, and Version 2.x and 3.x Tri-GP Logic

Solvers.
