MODBUS RTU TIA V 13 Logging Pressure from Pressure sensor

I have siemenns S7-1200 cpu and TIA V13
i have to create a apparatus which will be used to monitor pressure inside some test enclosures

it should monitor the pressure and transfer it to a data block
every 15 seconds it should record the presure and save it as a chart
i also have to select a pressure sensor i found one on the web which speaks Modbus RTU

i want to communicate with this sensor and record the log of pressure , if there is leakage the test is failed , if the pressure is stable and there is no leakage the enclosure will pass

This will show the modbus addresses of the sensor:

Thank you very Much Garry .

There is a datalog function in TIA as well.

Hello
Is it possible to Make a modbus program on PLC and then connect this PLC to my laptop via an ethernet cable and try to simulate the Logging by using some application on the laptop which will send data like the sensor does .

There are a couple of ways to simulate a Modbus TCP Server.
You could use a PLC simulator like the Do-More Designer software.
https://www.automationdirect.com/do-more/brx/software/simulator
This is a free programming and simulation package that includes drivers for Modbus RTU and TCP both Client and Server (Master and Slave)
Here is the download link:

The other option is to use EasyModbus.
https://sourceforge.net/projects/easymodbustcp/
This free package can be used to set up a Modbus TCP Server. I believe a sample program is already included in the package.

Here is a thread that combines both of these packages together.

Regards,

I have created the program in Siemens PLC , however the status keeps changing from 7001>7002>80C4
basically it tries to connect and then gets this error message 80C4
