call #v10A1

enable :="valveDB".v10A1.Enable DB24.Dbx0.0
Interlock :=
open_feedback := "mapped-do".D0_1.V10A1 DB104.DBx0.0
close_feedback := "valve DB".V10A1.Valve_off

Reset_valve_fault := "valve DB".V10A1.Reset_valve_fault DB24.0DBx0.4
valve_fail_time:= "valve DB".v10A1.valve_fail_time DB24.DbW2
Flash_trip:=

valve_on :="mapped-do".D0_1.v10A1 DB104.Dbx0.0
valve_off:=

open_ind:=
close_ind:=
time_out:=

mode := "valve DB".V10A1.mode DB24.DBw8
status:="valve DB".v10A1.status

valve_fail_count:= "valve DB".V10A1.Valve_fail_count
 
Have a look in the declaration(Top) area of the block you copied this code from, I would say #v10A1 is a FB/FC called in the STAT area.

If you right click on #v10A1 and select CALLED BLOCK/OPEN you will see the code from this call (if im correct :p)
