Introduction to the example
1.2 Structure and task of the example
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
