Figure 1. Industrial server iROBO

At the facility offered to install five identical interchangeable servers with pre-installed software. Such an arrangement allows the system in emergencies quickly recover the system by combining two servers into one. Also it is convenient when ordering components for those servers as they are unified within the system.

Each server has its own functionality.

The first server – IO server WinCC.

The second server – dubbed IO server WinCC.

The first two servers receive signals from automation objects and on the operator output information screens.

The third server is an archive (Historian) and provides up to three years of continuous accumulation of all possible historical data.

The fourth server – video surveillance and video archive.

Fifth – a reserve.

These servers are inserted into racks with transparent door (see. Fig. 2).

Figure 3. Monitor 19 ”

Means of visual control are assumed to placement on the operating point, which will be located in the 1st ABA.

Each screen is interchangeable and allows you to distribute objects so that the operator was convenient to carry out the monitoring. For example:

1st monitor: overall view;

2nd monitor: the approach to the place where the violation occurred.

To ensure the object of life is only three operators working in three shifts.

The task will be to alert the operator of operating personnel (electrical, automation specialist, engineer, chief engineer) of the contingency situation at the site, if necessary, intervention in the situation – security.

For the convenience of the control circuit hardware maintenance facility will be created “prompter” in a pop-up dialog box on the screen with buttons confirm the acceptance of the message.

All warnings and alarms issued by the operator, will be a sign of the priority from 1 to 999. Each message priority is divided by the degree of importance of a past event. This breakdown of events by priority allows the operator to more efficiently influence the process from the point of the importance of the event, as well as reduce the human impact on the management of the facility.

1.5.4 SIEMENS Automation

As a basic means of automation offered by SIEMENS controllers. The equipment of the firm selected by the Customer of the tender.
