Initializing the last execution if the ladder at online ladder block change has an FB call
• If a subroutine type FB is called in a FB definition, the execution information of the previous time in the FB definition of the
subroutine type FB is not initialized.
• If a macro type FB is called in the FB definition of a subroutine type, the execution information of the previous time in the
part equivalent to the macro type FB is not initialized either.

DSZR/DDSZR instruction, DVIT/DDVIT instruction, TBL instruction, DRVTBL instruction, PLSV/DPLSV instruction, DRVI/
DDRVI instruction, DRVA/DDRVA instruction, DRVMUL instruction, PLSY/DPLSV instruction, PWM/DPWM instruction, SPD/

The cautions at the time of repeatedly performing online change
When online change is performed repeatedly, RUN writing may not be able to be carried out due to insufficient memory in the
CPU module. Please set the CPU module to STOP and write the program.
The size of the target data at online change
When the size of the target data of online change exceeds 192 K bytes, online change fails and an error message is displayed
on the engineering tool. The target data size may exceed 192 K bytes in the following cases:
• When the capacity of the edited program file exceeds 192 K byte
• When the total capacity of multiple edited program files exceeds 192 K byte
In the above mentioned cases, divide the program file in advance to reduce each file size, avoid performing online change to
multiple program files at once (divide the files and perform online change several times), or take other actions.
*1 Usually, online change is performed to only edited files. However, in the following cases, online change is performed to a file other than
the edited file.
⋅ When a global label or structure is changed, the program using the changed global label and structure is a target of online change.
⋅ When FB or FUN is changed, the program using the changed FB and FUN is a target of online change.
For confirmation of the target file for online change and the file capacity, refer to the following.
