Register Types
This section describes global and local registers.
 Global Registers
Global registers are shared by ladder programs, user functions, motion programs, and
sequence programs. In other words, the operation results of a ladder program can be used by
other user functions, motion programs, or sequence programs.

4.1 User Program Types and Execution Timing
Description
These registers are prepared by the system.
They report the status of the Machine Con-
troller and other information.
The system clears the registers from
SW00000 to SW00049 to 0 at startup.
They have a battery backup.
These registers are used as interfaces
between programs.
They have a battery backup.
These registers are used as interfaces
between programs.
They do not have a battery backup.
These registers are used for input data.
These registers store the motion monitor
parameters.
These registers are used for Motion Mod-
ules.
These registers are used for CPU interface
input data.
These registers are used for output data.
These store the motion setting parameters.
These registers are used for Motion Mod-
ules.
These registers are used for CPU interface
output data.
These registers can be read in programs but
they cannot be written.
The values are set from the MPE720.
