Run subroutines from RAM (extension *.fst).

If the same subroutines are executed repeatedly during execution, it is more efficient to load
them into the RAM memory of the CNC because this way, they may be accessed faster and
execution time may be consequently optimized. This option is valid for OEM as well as for
user subroutines. To load a subroutine into RAM, it must have the extension fst. The reserved
RAM space for subroutines is 5 Mb.
User global variables.
User routines having a fst extension are loaded into RAM memory during block preparation.
The CNC checks whether or not it is loaded into RAM memory; if it is not and there is room
for it, it loads it.
At the end of the program (M30), if no other channel is executing subroutines, the CNC
deletes them from its RAM memory. This way, if a user subroutine having a fst extension
is edited or modified, the CNC assumes the changes the next time it executes it.
OEM subroutines.
• Being the CNC in USER mode, the OEM routines having a fst extension are loaded into
RAM memory when starting up the CNC application.
When the OEM is debugging his subroutines, they must have another extension so the
changes are assumed without having to restart the application. Once they are debugged,
the OEM must change the extension of the subroutines to fst so they are loaded into RAM
memory.
• Being the CNC in SETUP mode, the OEM subroutines whose extension is fst will be
loaded into RAM memory the first time they are executed in the program. This way, the
changes made in the subroutine will be taken into account the next time the program is
executed.
