| 7. In the "Connection partner" list, select the CPU "PLC_2". | |
| Result: You have set up the HMI connections from the HMI devices TP1900 Comfort to the | |
| CPUsChange the addresses of the PROFINET interfaces of the HMI devices and the CPUs for the PROFINET subnets 2 and 3 (PN/IE_2/3). |
Select the respective PROFINET interface of the device in the network view.
2. Change the address into a valid one in the subnet in the properties in the "Ethernet
addresses" area.
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 The user program implements 3 states in the tunnel:
Everything is OK: The air quality sensors measure values within the permissible range:
● 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 air quality sensors measure an increased concentration of pollutants between mean and
maximum value:
● 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 air quality sensors measure a pollutant concentration above the maximum value:
● 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.
Default tag table
The standard tag table contains the PLC tags for the 3 parts of the user program.The OB30 contains the user program of the tunnel application with three function blocks for:
● The fan control in the tunnel (FB10)
● The traffic light and barrier control (FB20)
● The lighting control in the tunnel (FB30)
● DB1 contains the HMI tags for the HMI screen.FB10 calls FB11. FB11 reports:
● The status of the air pollution level
● A pollutant concentration above the maximum value, which lasts longer than 2 minutes, to
block the tunnel
FB20 calls FB21. Depending on the status of the air pollution level (FB13) in the tunnel
sections, both traffic lights are set to green, yellow or red and the barriers are opened or
closed.Control of the entry and interior lights in the tunnel sections.
FB30 calls FB31. The user program controls the turn-on light according to the status of the
outdoor light sensor.
The user program controls the interior lights according to the respective time of day or
enables manual mode:
