8-3-7 Ladder Program for Debugging
The CX-Simulator can run a ladder program for debugging on the program
area for debugging (UM2) besides the program area for applications (UM1),
dynamically creating input data for virtual external inputs.
The program area for debugging is independent of that for applications,
sharing the I/O memory area with for applications. Thus the outputs from the
program area for debugging can be used as inputs to that for applications.
Note
Refer to
9 CPU Unit Operation
for the operation of the program areas for
applications/debugging.
Restrictions when Using Program Area for Debugging
Not possible to overlap with
the program area for
applications.
Do not overlap the task number with that of ladder program for applications. If
the task number overlaps, the task in the UM2 will not be executed. Besides, if
the following items overlap, a program error will occur.
•
The jump number of JMP
•
The subroutine number of subroutine/macro instructions
•
The block number of block programming instructions
Not possible to use interrupt
tasks
Do not use interrupt tasks in the program area for debugging (UM2). The
interrupt tasks in the UM2 will not be executed.
Program Area for Debugging
and I/O Break Condition
Setting
The program area for debugging is not displayed on the [Step Run] window. If
the I/O break condition holds whole executing a ladder program on the pro-
gram area for debugging, the [Step Run] window displays as if an I/O break
occurred at the end of the ladder program for applications (END).
