configuration and processing data will not be drop-out in one month.

State Diagnosis

Controllers real-time examine hardware errors and software faults and

obtain information on internal temperatures of control cabinets, operating

states of fans, failure states of power supplies, etc. When errors or faults

occur, in the system supervision software, system alarms will be triggered

and prompt operators by sounds and glinting diagrams, which are all

recorded in log files and can be queried.

Fault Safety

According to different technical requirements, AO/DO modules enter into

fault safe state after breaking communications with controllers, and then

the system can choose Output holding or Output preset safe value

according to predictive configurations.

After I/O modules enter into fault safe state, the system will prompt user to

perform corresponding maintenances via Fault safe state in the System

Supervision Software; and after the recovery of faults, the system will

prompt user to confirm the tags that had failure via Fault recovery list,

ensuring the safety of the system during the period of failure and at the

time of failure recovery.

Event Record


20/41

Control Station

16

The controller records key events such as initialization, configuration

downloading, system upgrading, redundancy switching, etc.

Redundancy

A pair of redundant controllers executes a same application program. The

work one is responsible for data acquisition, process control, exchanging

information on Process Control Network, etc. The standby one is used to

diagnose and monitor the state of the work one, and real-time backup the

information needed by control.

The work controller can switch to the standby one with no disturbance

when it gets out of order. The failure one can be overhauled after thecompletion of switching successfully, which will have no bad influence on

the control function. The key features of redundancy include:

Automat ic synchronization The redundancy function make

you do nothing about configuration. The controller can check

redundant configuration and implement redundant processing

automatically.

Real-time synchronization Between redundant controllers,

one complete data synchronization is fulfilled during a

scanning cycle.

Bumpless transfer The operation of controllers will not be

interrupted and the output channels will not be disturbed during

the transferring process.

Real-time mutual diagnosis Two redundant controllers

real-time diagnose mutually. When the work one gets out of

order, the standby one will switch to the work one in a control

cycle.

On-line replacementThe failure controller can be replaced

on-line and do not affect the control function of the work one.
