S7-1500R/H redundant system
Basic knowledge required
WARNING
Personal injury and damage to property may occur.
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.
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.
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
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.

Security information
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
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
1.2 Structure and task of the example
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
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 S71500H redundant system with two redundant H-CPUs is used to ensure fan availability.
Three fans ventilate 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.
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.

1.2 Structure and task of the example
The configuration consists of:
● When a CPU fails in redundant operation, the other CPU maintains control over the
tunnel operation.
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.
The Comfort Panels are used by operators as a control center for monitoring tunnel
operation.

1.2 Structure and task of the example
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
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.
in the CPU specifies limits and controls the input and output modules of
the ET 200SP.

S7-1500H versus S7-1500R
Advantages and benefits of the solution
1.2 Structure and task of the example
As an alternative to S7-1500H, you can use an S7-1500R redundant system for the solution
to the automation task. In this example, the S7-1500H redundant system is used as it offers
the following advantages for tunnel automation:
● much higher performance than S7-1500R with:
– separate redundancy connections over fiber-optic cable
– high computing power
– a higher number of PROFINET devices can be used
● distance between the two H CPUs up to 10 km
● High availability of the system: If an H-CPU fails or is being maintained, the lighting and
fan control continues to function. The tunnel does not need to be blocked.
● Reliable monitoring and control of the tunnel facilities over large distances, up to 10 km
between the two H-CPUs
● Monitoring of the system and targeted information of the operating engineers in real time
● Signals are recorded and output directly in the ET 200SP distributed I/O systems in the
tunnel. There are no long cable runs.

Configuring H CPUs
Introduction
2.2 Configuring H CPUs
You create two redundancy connections between the H-CPUs via fiber-optic cables using a
total of four synchronization modules (two in each H-CPU). You replace the synchronization
modules (for cables up to 10 km in length) in STEP 7.
STEP 7 automatically assigns an IP address to each PROFINET interface of a CPU. You
can also assign the IP addresses manually. For PROFINET interface X1 of the CPUs, the IP
addresses must be located in the same subnet. In the example you accept the preset IP
addresses.
STEP 7 assigns default values for the minimum and maximum cycle times. Select the
minimum scan cycle time so that the cyclic program does not have to be executed more
frequently than your process requires.

2.4 Configuring HMI devices
Assign names for the two HMI devices.
Connect the HMI devices to the redundant system as follows:
● Network the HMI devices with an H-CPU in each case.
● Configure two HMI connections.
● Assign the system IP address of a PROFINET interface of the H-CPU or
● Use the device IP address of the respective PROFINET interface of the two H-CPUs
Recommendation: Configure the HMI devices with the HMI Device Wizard. The HMI device
wizard will guide you through each dialog step by step and help you set up an HMI device.
The HMI device wizard will automatically start when you create a new HMI device in your
project via the project navigation.
When connecting via the device IP address, the HMI device always communicates with the
connected CPU. Communication is independent of the system state. The connected CPU
then synchronizes the data with the other CPU.
Requirements: Each HMI device is connected to a CPU via a separate subnet.
In the example, the TP1900 Comforts communicate in each case via the devices IP address
of the PROFINET interface with the directly connected CPU.
1. Select the left-hand TP1900 Comfort in the network view.
2. Change to the device view.

Introduction
The example consists of three parts:
● The air quality measurement and fan control in the tunnel
● The traffic light and barrier control
● The lighting control in the tunnel
The following section explains, based on flow diagrams, how the user program works.
Using an HMI screen, you can switch the fans and the lighting in the tunnel from automatic to
manual mode and, if necessary, change limit values.
The user program runs on a CPU 1517H-3 PN with SIMATIC STEP 7 Professional, Version
V15.1.
The executable user program for the example can be found in the annex to the entry on the
Internet (https://support.industry.siemens.com/cs/us/en/view/109757712).

The user program implements 3 states in the tunnel:
● The traffic lights are green.
● The barriers are open.
● The motors for ventilation are in Stop mode, only the flow of air moves the fans.
● The fans immediately run at low level (slow) for at least 30 seconds. The direction of
rotation of the fans depends on the extent of the load in the tunnel section and the
distance to the exit.
● The traffic lights are still green.
● The barriers are still open.
● The fans run immediately at the highest level (fast) for at least 30 seconds. The direction
of rotation of the fans depends on the affected tunnel section and the distance to the exit.
● If the fans did not provide sufficient air within 2 minutes, the tunnel will be blocked:
– The traffic lights are first yellow, then red.
– The barriers close.
The standard tag table contains the PLC tags for the 3 parts of the user program.
