I want to stop charging if Soc is 80% and restart charging im Soc is less than 40%.
I have a Quattro, CCGX und an Ve.Bus BMS (REC-A)
Where can I set this parameter ?

There is no direct way to achieve this, but it should still be possible without too much trouble...
You could use the CCGX generator start/stop functionality with SOC% set as the only trigger condition.

Then physically wire the CCGX relay to one of the 'Aux In' terminals on Quattro unit and use the '2 signal BMS' assistant to enable/disable the charger totally or even force it into float phase >80% SOC.
Also see my answer to your other related question for more information on using assistants.
Perfect...I think it is really easy with the Generator start/stop functionality to programm the SoC (via Aux-In 1 and CCGX relais).
And for start/stop charging I can use the current control assistant with the option to disable the charger at 0A charge current enabled and both trigger voltages set to ~2v.
(via Aux In 2 , 12V on /off via a Push Button)
The generator start/stop relay logic cannot be inverted, so with a CCGX you need to work with the logic of Genset on = relay closed / Genset off = relay open. If using a Venus GX you have the open to use the NC relay contacts (instead of NO) to invert the operation.
To setup the generator start/stop logic;
1- Set the relay function to 'generator start/stop'
2- Enable 'Auto start functionality'
3- Under settings > Conditions select the desired trigger condition(s)
4- Enable the desired condition(s) and set the desired thresholds
To setup the 2 signal BMS assistant logic (to disable/enable the charger);
1- In the 'VEConfigure battery type selection' screen select the 1st option - 'Do not change battery type'
2- In the 'BMS options' screen select the 2nd option - 'The BMS has one contact which switches only on a high-cell condition'
3- In the ' Battery state input' screen select 'The battery is full when Auxiliary input 1 is open'
4- In the Action' screen select 'Disable charger (or force to float if desired) and do not adapt SOC when battery full'
5- Review the 'Information' summary screen to ensure the assistant is setup correctly
