Example #3:
This is another method for achieving the same results as example 2.

(Flash "Pallet Ready" light - wait until PALLET READY button pressed to
continue)

Example #1:
Basic pallet change program that loads the next scheduled pallet and runs the correct parts program. The next
pallet and the correct program are determined from the PST. Below is a sample of a Pallet Schedule Table
(Sample Table 1). The table indicates that pallets #2, #3 and #4 are scheduled and that pallet #1 is unsched-
uled (column 3 “Pallet Status”). The pallets will be processed in the order #3, #4 and finally #2 (column 2 “Load
Order”) with the program indicated in column 5, “Program Number”. The “Program Comment” is captured from
the program listed in column 5.

M49 Q12
Set current pallet status to 12 actual string defined by operator, in this case
status number 12 is defined as “LAST PALLET”
M99
(Return from subroutine)
Description: The first loop through program O00001 will load pallet #3 (M50) and run program O04990 (G188
selects program from PST for pallet #3). The PST will then resemble Sample Table 2. The asterisk for pallet #3
in the “Load Order” column indicates that this pallet is in the mill.
