Modbus TCP / multiple variables and data formats

Hi,
This is very good Project! I started to work with this programm. As an begginer I cannot find two data formats that I need for my Modbus variables'definition:
— u64 — unsigned 64-bit (4 registers)
— s64 — signed 64-bit (4 registers)
How can I set this type of data?

Also I have another question. Can I define reading schema for reading of one device with multiple variables in text redactor or in excel and after this to import the parametrization data into the programm? Can I save parametrization and copy/paste for multiple devices?

Good luck with project!

ADDING TWO OR MORE MODBUS VARIABLES.

Hello,

I would like to create an «AnalogueTextValue» the will show the sum of four (4) MODBUS variables.
I have already tried to use the Simulation Settings and create a new variable_1, but I am not very familiar with the Python Syntax to do it correctly.
Can someone help me?

Thanx,
Dimitris
