[ b ] Executing H Drawings by MSEE Command
Motion programs are always called from H drawings using the MSEE command (motion program call command).
Motion programs can be called from any parent, child, or grandchild drawing in an H drawing.
The following figure shows an example of motion program execution.
H drawing ladder commands are executed in hierarchical order i.e., parent drawings, child drawings, then grandchild
drawings each high-speed scan cycle.
The above method is a preparation for running a motion program. When a MSEE command is built in, the motion pro-
gram does not start up. To start up the motion program, after the MSEE command is incorporated, use a control signal
to turn on the request for the program operation startup.
Motion programs are also called each scan cycle, but unlike ladder programs, all motion programs cannot be executed
in one scan. For this reason, motion programs are executed and controlled by special system’s motion management
function.
Caution
When running a motion program, pay attention to the followings:
• The motion program registered in M-EXECUTOR cannot be executed using a MSEE command.
• Multiple motion programs with the same number cannot be executed using a MSEE command.
• A subroutine (MPS
) cannot be executed from a MSEE command in a ladder.
It can only be referenced from a motion program (MPM
, MPS ).
• A sequence program (SPM
, SPS ) cannot be executed from a MSEE command in a ladder.
• The same subroutine cannot be referenced at the same time.
