Introduction to the example

Redundant automation systems are used in practice to achieve greater availability. In

redundantly operated systems, failure or malfunction of individual automation components

must not impede the operation of the plant.

S7-1500R/H redundant system

For the S7-1500R/H redundant system, the CPUs are duplicated, in other words redundant.

The two CPUs process the same project data and the same user program in parallel. The

two CPUs are synchronized over redundancy connections. If one CPU fails, the other CPU

maintains control of the process.

Basic knowledge required

The Getting Started guides you through the configuration and programming of an S7-1500H

redundant system using a concrete example. The following knowledge is required in order to

understand the Getting Started:

●General knowledge of automation technology

●Knowledge of requirements for high availability of automation systems

●Knowledge of the engineering system STEP 7 V15.1

WARNING

Personal injury and damage to property may occur.

The S7-1500 as a component of plants or systems is governed by specific standards and

regulations, based on the relevant field of application. Please observe the applicable safety

and accident prevention regulations such as IEC 60204-1 (general machine safety

requirements).

The example in this Getting Started serves as an introduction to the configuration and

programming of an S7-1500H redundant system. It cannot always and in every case be

transferred to effective live operations. Before you do this, you are urgently advised to

consult the current version of the system manual "SIMATIC S7-1500R/H redundant

system" and the device manuals of the modules used. The warnings and other information

there must be observed, even if they are not repeated in this Getting Started.

Failure to observe these regulations can result in serious injuries and damages to

machinery and facilities.

1.1

Security information

Siemens provides products and solutions with industrial security functions that support the

secure operation of plants, systems, machines and networks.

In order to protect plants, systems, machines and networks against cyber threats, it is

necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial

security concept. Siemens' products and solutions constitute one element of such a concept.

Customers are responsible for preventing unauthorized access to their plants, systems,

machines and networks. Such systems, machines and components should only be

connected to an enterprise network or the internet if and to the extent such a connection is

necessary and only when appropriate security measures (e.g. firewalls and/or network

segmentation) are in place.

For additional information on industrial security measures that may be implemented, please

visit (https://www.siemens.com/industrialsecurity).

Siemens' products and solutions undergo continuous development to make them more

secure. Siemens strongly recommends that product updates are applied as soon as they are

available and that the latest product versions are used. Use of product versions that are no

longer supported, and failure to apply the latest updates may increase customers' exposure

to cyber threats.

Structure and task of the example

Automation task light and fan control in a tunnel

The continuing increase in traffic volumes coupled with growing safety requirements demand

state-of-the-art tunnel systems. At the same time, equipment requirements for these

constructions are rising, especially when it comes to maximum safety and availability.

The example below comprises three subtasks:

●Control of the safety ventilation as a function of the air pollution level in the tunnel

●Control of the traffic lights and the barriers as a function of the air pollution level in the

tunnel

●Control of the lighting in the tunnel as a function of the illuminance of the outdoor light

Figure 1-1 Example Light and fan control tunnel

Control of the safety ventilation as a function of the air pollution level in the tunnel

Fans are used in the tunnel to extract harmful exhaust gases and supply fresh air.

Uninterrupted operation of the ventilation system is required to keep the concentration of

pollutants below a set level. Constant availability must be ensured for the event that

individual automation components fail, for example because of a fire in the tunnel. The S7-

1500H redundant system with two redundant H-CPUs is used to ensure fan availability.

Three fans ventilate the tunnel.

Control of the traffic lights and the barriers as a function of the air pollution level in the tunnel

The tunnel entries are controlled via two traffic lights. The traffic light control also requires

higher availability for safety reasons.

If the pollutant concentration exceeds a maximum limit for more than 2 minutes in a tunnel

section, then the tunnel is blocked.

Control of the lighting in the tunnel as a function of the illuminance of the outdoor light

The abrupt transition between light and dark at the entry to the tunnel is compensated for by

tunnel lighting in the various tunnel sections. Two light sensors measure the light intensity

outside the tunnel. The light intensity of the entry lights in the tunnel is controlled accordingly.

The interior lights in the tunnel are controlled by the prevailing daytime / nighttime.

Automation components of the example

The configuration consists of:

2 S7-1500 H-CPUs

●When a CPU fails in redundant operation, the other CPU maintains control over the

tunnel operation.

3 ET 200SP as IO devices in the PROFINET ring

An ET 200SP (IO device) distributed I/O system is found in every tunnel section (1 to 3).

Sensors and actuators are connected to each IO device for the following tasks:

●Measurement of the pollutant concentration and as a function thereof:

–Control of the fan speed and air flow

–Control of the traffic lights and barriers

●Measurement of the light outside the tunnel:

–Control of the entry lights

●Control of the interior lights in the tunnel, depending on the day / night time.

2 Comfort Panels

The Comfort Panels are used by operators as a control center for monitoring tunnel

operation.

S7-1500R/H redundant system

Getting Started, 10/2018, A5E44910930-AA 9

Principle of operation

Controlling the speed of the fans and controlling the traffic lights and barriers

Every fan:

●has two speeds (stages), which are switched on or off depending on the measured

pollutant concentration.

●has 2 directions of rotation. Depending on whether pollution is measured, the fan must

blow or suck.

The H-CPU measures the pollutant concentrations in the tunnel via analog input modules

and air-quality sensors.

If the pollutant concentration exceeds the maximum limit, the H-CPU responds in ET 200SP

via digital output modules as follows:

●It increases the speed of the fan motors

●It switches the traffic light system to red after two minutes

●It closes the barriers after two minutes

If the pollutant concentration falls below an average limit, the H-CPU responds in ET 200SP

via digital output modules as follows:

●It switches the ventilation motors to stop

●It switches the traffic lights to green

●It opens the barriers

Controlling the lighting in the tunnel

The H-CPU measures the light intensity outside and inside the tunnel using analog input

modules. Depending on the outdoor light, digital output modules adjust the brightness of the

entry lights in the tunnel to the optimum vision conditions. The digital output modules also

control the interior lights in the tunnel, depending on the day / night time.

The user program

in the CPU specifies limits and controls the input and output modules of

the ET 200SP.

The Comfort Panels

visualize the S7-1500H redundant system in an HMI screen. If required,

the operator can switch to manual operation via the HMI screen and change limit values.
