H41q/H51q Safety Systems

... the safe decision. 1 (MM 9912)H41qH51q_9912_e.ppt



• Technology characterized by double

processors on each central unit.

• Safety related single channel systems up to

AK6/SIL3 without any restrictions.

• Communication with the second central unit by

a fast Dual Port RAM (DPR).

• Realisation of a 2oo4/QMR architecture

(Quadruple Modular Redundant)

• Maximum availability and fault tolerance with a

redundant system.

HIQuad Technology - The new dimension of Safety



The new central module

• Double processor and hardware comparator

on each central unit. (HIQuad Technology)

• certified up to AK6/SIL3

• Optimum diagnostic coverage factor and

diagnosis.

• ELOP II programming in conformance with

IEC 61131-3.



Technics of the Central Module



Configuration of Availability

• H41q - System: Single-rack-system suitable up to 192 I/O points.

• H51q - System: Modular extendable system



MS-System: Safety and Availability



HS-System: Safety and high Availability



HRS-System: Safety and highest Availability



Scalable Availability



Scalable Availability - Advantages

• Individual configuration of CPU-level

and I/O-level.

• any scalable availability is possible.

• Building up reliable and cost-effective

solutions.



Availability and Safety with less cost

H41q/H51q TMR



Cost effective Availability and Safety

• H41q/H51q - solution needs less

hardware:

high potential to reduce costs.

• H41q/H51q - solution is easy

structured and has a better MTTF:

high reliability.

• The 2out of4/QMR-architecture of

H41q/H51q is insensitive to

"common cause" failure.



Operation under fault conditions

• Single reconfiguration of CPU-level and I/O-level

• High fault tolerance and high process availability

Reduction of life cycle cost

• tailor made system configuration

• System AK6 inherently.• Simple and flexible configuration.• Wide range of communication.• Programming with ELOPII-NT.

• Pre-fabricated standard components.• Complete diagnosis of the system.• Offline-simulation with ELOP II-NT.

• tried and tested components.• easy to extend.• all components are hot replaceable.• remote diagnosis.• High fault tolerance, therefore no plant

stop.
