HA and global parameters

Dear All,
I have some issue becouse of use of HA rather as scada system.
There is some global parameters not coccected with any entity like hours, numbers etc needed to set up in my PLC via modbus. It is needed for automation on PLC site.
How can I do that/ It is possible with input_number ie?

Dear All,
Maybe from other site.
Suppose that I will put all global paramaters in particular components and combine with.
Let’s take Modbus switch. How can I set default and membered value for slider not from input_number component but from other modbus register?
I would like to make modbus light with slider and remember default value also in modbus register.
How can I do that? Should I make some custom component?
