Overview
1
The guide is to be used with the accompanying sample TIA Portal project (LT500 TIA PBPN
V1_00) and video tutorial. The guide and video demonstrate how the SITRANS LT500 with
PROFIBUS and PROFINET communication modules are configured in TIA Portal.
The sample project demonstrates how to:
1. Install a GSD or GSDML file.
2. Set the PROFINET device name for the SITRANS LT500.
3. Configure the hardware and process values.
4. Create a PLC tag table.
5. Create a watch table to read/write the process values.

Objective
3
The objective of this application guide is to become familiar with the configuring the SITRANS
LT500 in Siemens TIA Portal V16. Configure a PROFIBUS and PROFINET LT500 and read and
write process data.

Hardware setup
4
The user should be familiar with TIA Portal.
With the relevant communication module inserted in to the SITRANS LT500 and wiring
completed as per the instruction manual, you are ready to start configuration with TIA Portal.
Reminder
If you are connecting the SITRANS LT500 on a PROFIBUS DP network, ensure the termination
switches are “ON” or “OFF”. If the SITRANS LT500 is at the end of the PROFIBUS DP network,
you must set the termination switches to “ON” on the communication module.
If you are connecting the SITRANS LT500 on PROFINET, you will need to connect your
ethernet cable to your ethernet switch or spare port on your CPU.

Step 1: Installing the GSD or GSDML file
5
First, install the GSD and GSDML files into TIA Portal. In this step, we demonstrate how to
install the GSDML file for the PROFINET communication module. The procedure is the same
for the PROFIBUS DP GSD file.
1. On the SITRANS LT500 product page, go to the “Support” tab and then select “Downloads”.
Choose the PROFINET GSDML link for the PROFINET Communication module and download
the XML file and BMP picture file.
2. Open TIA Portal and select “Manage general station descriptions files” from the “Settings”
menu.
3. Browse to where you saved the GSDML file and select the folder.

Step 1: Installing the GSD or GSDML file

4. Select the GSDML file and click “Install”.
5. Once the GSDML file has been installed, you can "close". TIA Portal will now update its
hardware catalog with the new GSDML file.

Step 2: Setting the device name
6
Start TIA Portal and open the sample project, “LT500 TIA PBPN V1.00”
The first step in setting up our SITRANS LT500 on a PROFINET network is to assign it a device
name.
In TIA Portal the is a function to scan the PROFINET network for devices.
1. Using the “Online access”, select the network card you are using to connect to your network
and click on the “Update accessible devices”.

Step 2: Setting the device name

Application examples, 04/2022, AG022322 11
2. Select the device on your network which only shows a MAC address, confirm this is the
SITRANS LT500 by looking at the HMI and going to the “Communications” menu to view the
MAC address.
3. Select “Online & Diagnostics” and go online to the SITRANS LT500.
4. Enter the PROFINET device name and select “Assign name” to set the device name, and close
the online window.

Step 2: Setting the device name

5. Once again, select “Update accessible nodes” to rescan the network.
6. The LT500 now has a device name.

Step 3: Setting up the device modules and process
values
7
1. Expand the project tree and double-click “Devices and Networks”. In the “Devices and
Networks” window, double-click on the SITRANS LT500 connected to the PROFINET network
to open the device and show the device module configuration.

Step 3: Setting up the device modules and process values

14 Application examples, 04/2022, AG022322
2. In the sample project, we have already added some modules. You can change the module
configuration if you require other process variables.

Step 3: Setting up the device modules and process values
SITRANS LT500 with PROFIBUS and PROFINET in TIA Portal V16
Application examples, 04/2022, AG022322 15
3. We have inserted:
- Level module PT1
- Volume Flow PT1
- Sensor temperature PT1
- Totalizer Volume with control (32 bit)
- Totalizer volume with control high precision (64 bit)
- Relay status
Notice we have assigned addresses to the I and Q addresses for each module. These will
be used in our TAG table.
Note
To add or change the modules, you can select a different module from the Module list.
Drag the module in to the relevant slot and enter the I or Q address depending if the
module is an input or output.
4. Double-click on the SITRANS LT500 to show the properties of the device.
5. In the properties window, enter the device name (in our example “LT500” and the IP
address, in our example “192.168.1.77”) however your IP address may be different due to
your local subnet settings.
6. Click on the “network view” so we can look at the PROFIBUS DP setup.

Step 3: Setting up the device modules and process values

16 Application examples, 04/2022, AG022322
7. From the network view, double-click on the SITRANS LT500 connected to the PROFIBUS DP
network.
8. Just like the PROFINET module configuration, we have I and Q address assigned to the
various module process values. In our example we have inserted:
- Level module PT1
- Volume module PT1
- Sensor temperature PT1
- Relay status module
Note
To add or
change the modules, you can select a different module from the Module list.
Before adding a new module, you need to delete the original module from the slot. If no
module was originally there, you delete the
“No cyclic data transfer” module and then
drag the new module in from the module list into the slot.

Step 3: Setting up the device modules and process values

9. Double-click on the SITRANS LT500 to open the properties. In the properties window, enter
the PROFIBUS slave address for the SITRANS LT500. This is the address that you enter in to
the HMI under “Communications” “Slave address”.
Note
If you want to add additional SITRANS LT500s to the network, you can do so by adding
them from the device catalo
g.
In the
“network view”, drag the SITRANS LT500 from the catalog for either PROFIBUS or
PROFINET.
Click on the blue writing “Not assigned” on the SITRANS LT500 to connect it to a PROFINET
network.

For PROFIBUS DP, click on the blue writing “Not Assigned” on the SITRANS LT500 to
connect it to the DP bus.

Step 4: Setting up the PLC TAG table
8
1. We now need to assign TAG names to the I and Q memory addresses that we assigned in
our hardware configuration.
2. Navigate to the “PLC Tag” list under the “S7-1500” PLC and double-click on it to open the tag
list.
3. In our sample project, we have assigned TAG names and data types to the I and Q addresses
for the PROFINET modules. The TAG list will be used by the PLC program or Watch table to
read and write data to the SITRANS LT500.

Step 4: Setting up the PLC TAG table

4. Highlight the S7-1500 from the main project tree and then select “Download to device” from
the “Online” menu.
