Language scope for SAFE.SPF

In order that no NC alarms are output when the SINUMERIK control boots, which
prevent a started SAFE.SPF being completely executed, it is necessary to define a
restricted language scope for SAFE.SPF. It is not permissible that commands are
programmed which access the PLC or drives.
If a SAFE.SPF is tested or commissioned with a restricted language scope, then
every Alarm 15189 "Channel %1 Block %2 Error when executing SAFE.SPF"
requires a power on. MD10095: $MN_SAFE_MODE_MASK, bit 2 can be set to 1
in order to prevent this.
Now, the restricted language scope is active each time that SAFE.SPF is called
using the command CALL<path name>. For instance, the call can be made from
MDI or PROG_EVENT.SPF at reset. For commands, which are not included in the
language scope, only Alarm 15420 "Channel %1 Channel %2 Instruction in current
mode not allowed" is output and not Alarm 15189. Alarm 15420 can be cleared
with a reset.
In order to change over an existing SAFE.SPF to a restricted language scope, it is
possible to proceed as follows for example:
-- MD20108 $MC_PROG_EVENT_MASK, bit 5=0
-- In the PROG_EVENT.SPF, remove the SAFE.SPF call from the power on
section or the SAFE.SPF call from the ASUB.
-- MD10095 $MN_SAFE_MODE_MASK, bit 2=1
-- SAFE.SPF is not called when the system boots
-- SAFE.SPF is now called with CALL "_N_CMA_DIR_/_N_SAFE_SPF" e.g.
from MDI or PROG_EVENT at RESET. The restricted language scope is
now active, alarms that occur can be cleared with RESET.
