how to calculate ABI to call some variable in contract?
for example
contract X
uint data;
function Y(uint a)
How to calculate signature to call variable "data" ?
I know to call function we should do something like that keccak256("Y(uint)") but if we want to call variable ?

All public variables generate a getter with the same name as the variable. So a variable with name data will result in a function with signature function data().
Therefore, if you want, you can calculate the call signature with the formula you provided.

solc will generate the ABI for you (as will remix and truffle)
Just run solc --abi yourfile.sol.
You can see a list of compiler options here.
