2.1.1 Cautions for editing ladder programs
The maximum number of editable lines is 9,999.
The maximum number of lines that can be edited for one ladder program window by
the Ladder Builder for KV is 9,999. The maximum size of one block is 100 lines.
Keep in mind that a ladder program exceeding 9,999 lines cannot be created.
When the program is running slowly
When many applications are simultaneously running on a personal computer with
low memory capacity, the memory and the source become insufficient. As a result,
the swap file is frequently accessed and operating speed deteriorates. If this occurs,
close other applications to decrease the load on the system.
It is also effective to increase the memory.
