There is no such block, you must combine the existing blocks to achieve this.

Is there also a function block that if the input is high it will bring the analog output to 100% if it is still high then counts back to 0% and if it is still high it will go back to 100%?

see this example project: 0203-03 Built-in functions

As for switching string signals, use the SELSOCT block. For 20 strings, you'll need 3 of them. Did you miss it in the list of functions blocks for processing string signals in REXYGEN?

Hope this helps, let me know.

But can I also switch between string that I get, for example, string 1 when input 1 goes high and string 2 when input goes high and so on until string 20

Hi Martijn,

REXLANG:
you can create substring in REXLANG using function

string strsub(str,idx,len)

Returns a substring of length len starting at index idx

For more details on String functions in REXLANG see docs: https://www.rexygen.com/doc/PDF/ENGLISH/BRef_ENG.pdf#page=442

Function blocks:
It is also possible to create substring using function block called MID.
For more details on String Function blocks see docs:

Regards, Tomas
