Program Structure of DVP-PM
Explanations on the program design:
1.
The compiling sequence is from (1) to (5), but there is not a rule for the sequence of how and where you
place them.
2.
There can only be one O100 main program (2), and it cannot be called by other programs. O100 can call
OX motion subroutines and Pn subroutines.
3.
OX motion subroutine can be called by O100 main program and Pn subroutine, and it can also call a Pn
subroutine.
4.
Pn subroutine can be called by O100 main program and OX motion subroutine, and it can also call a OX
motion subroutine.
Note:
1.
More then two OX motion subroutines cannot be executed at the same time. Therefore, when OX0
motion subroutine is executed, OX3 will not be able to work, and vice versa.
2.
Once O100 main program or Pn subroutine enables an OX motion subroutine, it will continue to execute
the next row of the program without paying attention to the OX motion subroutine.
3.
The enabled OX motion subroutine will only execute once. If you want it to execute again, you have to
re-enable it.

Called by OX motion
subroutine; therefore,
motion instructions
and G-Code
instructions are
supported.
Called by O100 main
program; therefore,
motion instructions
and G-Code
instructions are not
supported.
