Z7128 HIMA cable plug DCS/PLC automation series

Description

Z7128 To improve availability, all parts of the system including active components can be set up

redundantly and, if necessary, replaced while the system is operating.

The component redundancy does not impair Z7128 the system safety. Safety integrity level 3 (SIL 3) is

guaranteed.

Redundancy affects the PFD and PFH values of the HIQuad X system, see Chapter 3.1.1.

Z7128 Structuring Safety Systems in Accordance with the Energize to Trip Principle

Safety systems operating in accordance with the energize to trip principle have the following

function:

1. The safe state of a module is the de-energized state. Z7128 This state is adopted, for instance, if a

fault has occurred in the module.

2. The controller can trigger the safety function on demand by switching on an actuator.

3.1.5.1

Detection of Failed System Components

Z7128 Thanks to the automatic diagnostic function, the safety system is able to detect that modules

have failed.

3.1.5.2

Safety Function in Accordance with the Energize to Trip Principle

The safety function is performed when the safety system energizes one or several actuators.

The user must plan the following actions:

 Include and configure a redundant module for Z7128 every I/O module.

 Every I/O module must be provided with short-circuit and open-circuit monitoring. The short

circuit and open-circuit monitoring must be configured for each channel.

 The operation of the actuators can be monitored through a position feedback.

3.1.5.3

Redundancy of Components

It may be necessary to redundantly structure the following components:

Power supply of the controller.

HIQuad X modules.

Sensors and actuators.

If redundancy is lost, Z7128 the controller must be repaired as soon as possible.

For details on component redundancy, refer to the system manual (HI 803 211 E).

It is not required to design the safety system modules redundantly if, in the event of a safety

system failure, the required safety level can otherwise be achieved, e.g., by implementing

organizational measures.
