PBSE1095 DSQC661 3HAC026253-001 ABB Power module

Description

DSQC661 Communication with engineering tools can be controlled by the isolation key switch on the

local panel and/or by a successful isolation of the safety controller.

2.1.7.3 Override control and reset

DSQC661 The number of simultaneously occurring overrides are controlled by a configuration parameter.

The reset of the overridden signals can be done in several ways:

• The primary reset of overrides is via normal communicated dialog operations (manual

entry).

• A hard wired input to the Safeguard 400 Series DSQC661 is the secondary possibility for reset of all

overrides in the safety system, independent of communication with any operator stations.

• Automatic reset of all overrides in case of loss of communication with all access granted

operator stations.

• Automatic reset of all overrides in case of maximum allowed time exceeded timed from

the first occurring override.

The number of configured and active overrides are presented on the operator station and it is

also possible to configure any active override in the DSQC661 system as an activation of a dedicated

digital output.

All activation and de-activation of overrides is recorded on the operator station event list.

2.2 Operator Interface Software

2.2.1 General

The basic operator interface software, named AdvaCommand, is available for the HP-UX-based

Advant Station 500 Operator Station and for a Windows NT-based PC. AdvaCommand is a

family of operator control and interaction functions.

It provides functions for presentation of safety and process information, command entry, event

and alarm handling, system status, window handling, process sectioning and status lists.

The AdvaCommand Safeguard Handler is an option which is required for handling of the

Safeguard 400 Series products. All Advant Station 500 Operator Station series can also be

delivered with the AdvaCommand Safeguard Handler option.

All Advant Operator Workplace functions are DSQC661 retained when used with the Safeguard 400

Series. This means that the product can be used as a common operator station for safety and

process control.

With AdvaCommand Safeguard Handler the following functions are added to the basic

Operator station:

• A dual system handler that allows both branches of the Safeguard 400 Series to appear as

one object to the operator. This gives:

– Single presentation of alarms in lists and on printer.

– Single presentation of objects.

– Dialogue handler with commands sent to both safety controllers.

NOTE

If the operator workplace is used in a plant network, the node number must be

unique in all the connected control networks. This is due to limitations in the dual

handling function in the operator station.

• Presentation and interaction for safety object types, e.g. detection and protection systems,

required by Safeguard 400 Series is added to the standard operator station functionality.

This consists of Object (Faceplate) displays, group displays and display elements as well

as dialogs. The following safety object types are available in the Safeguard Handler:

– FI (Fire Input), Loop monitored digital inputs

– FD, for addressable Fire Detector signals

– GI, for Gas input signals

– Safety System Status, diagnostic status display for Safeguard 400 Series

– FG, diagnostic status display for Fireguard
