DEBUGGING FUNCTION
To write from the GPP function peripheral devices during RUN, the following two methods
are available:
(1) After a ladder is created in the ladder mode, write during RUN is performed by
pressing
+
keys for conversion of the ladder.
(2) With "4. Write/conversion setting" in "8/ Option" menu of the ladder mode, "4. Write
setting during RUN" and "7. Write method during RUN" are set.
When the
key is pressed for conversion of the ladder after the ladder is
created, write during RUN is performed.
The following shows the setting examples:
(a) In "4. Write setting during RUN," "1. ( ) After conversion, PLC is written during
RUN" is set.
(b) In "7. Write method during RUN," "1. ( ) Write during normal RUN" or "2. ( ) Write
during relative RUN with pointer" is selected.
NOTE
The following shows the precautions relating to write during RUN.
(1) The only memory that can be used for write during RUN is the built-in RAM. If write
during RUN is performed during a boot operation, also write the program to the
memory card at STOP.
When the boot operation is started again without write on the memory card, the
program before write during RUN is transferred from the memory card to the built-in
RAM for execution.
(2) The maximum number of steps that can be handled in one write during RUN
operation is 512.
The number can be changed according to how many steps of write during RUN
saved using a peripheral device capable of GPP function. The saved steps of write
during RUN can be set during the CPU module OFF. Note that the saved steps of
write during RUN decrease every time write during RUN is performed.
