s7-1500 and tank level meter modbus RTU

[bentec]

I use an S7-1500, an MTP1200 Comfort Unified, and a WinCC V8 station. The S7-1500 communicates with a tank level meter via Modbus RTU (RS-485).

At the operator's request, I must read a tank profile composed of 250 points, each point containing the position, temperature, and density.

What is the recommended method for:

- storing these 100 samples;

- displaying the three curves (Position, Temperature, and Density) on the MTP1000 Unified and WinCC V8;

- recalling and displaying an recorded profile?

Thank you for your help.
