Monitoring Motion Program Execution Information
The execution information for motion programs can be monitored using the S registers (SW03200 to
SW05119 and SW08192 to SW09125).
The execution information is monitored differently, depending on whether the motion program is called
from a ladder program with an MSEE instruction, or the motion program is registered in the M-EXECU-
TOR program execution definitions.
This section describes these two monitoring methods.
• When the Motion Program Is Called from the Ladder Program with an MSEE Instruction
When a motion program is called from the ladder program with an MSEE instruction, the monitoring
method depends on the setting of bit D (System Work Number Setting) in the Motion Program Control
Signals.
• When the Motion Program Is Registered in the M-EXECUTOR Program Execution Definitions:
When the motion program is registered in the M-EXECUTOR program execution definitions, the system
work number used will be the same as the program execution registration number in the M-EXECUTOR.
For example, if the motion program is registered for execution as number 3, system work number 3 is
used. You can therefore monitor the execution information of the motion program with the Work 3 Pro-
gram Information registers (SW03380 to SW03437).
When using MSEE instructions in ladder programs along with the M-EXECUTOR, do not specify the
system work numbers that are for the M-EXECUTOR in the MSEE instructions in the ladder programs.
If you specify one, a No System Work Error will occur.
System work numbers for the M-EXECUTOR: 0 to the set value of the number of program definitions
You cannot set the system work numbers when you use the M-EXECUTOR. The system will use
system work numbers that are the same as the definition numbers.

Monitoring
ON
The execution information is reported in the Work n Program Information
registers (SW03264 to SW05119 and SW08192 to SW09125).
For example, if the system work number is 1, you can monitor the execution
information of the motion program with the Work 1 Program Information
registers (SW03264 to SW03321).
OFF
The system automatically determines the system work number to use.
You can check the work numbers that are in use in the Active Program Num-
bers registers (SW03200 to SW03231).
For example, if MPM001 is the motion program to be monitored and
SW03202 contains a 1, the system work number is 3. You can therefore mon-
itor the execution information of the motion program with the Work 3 Pro-
gram Information registers (SW03380 to SW03437).
