WARNING
1 If a message data for multi-language display is read
while ladder program is being executed, the ladder
program being executed is automatically stopped.
Take special care when stopping a ladder program.
If a ladder program is stopped at an inadequate
timing or in an inadequate machine state, the
machine can make an unexpected movement.
Moreover, when a ladder program is stopped, the
safety feature and monitoring based on the ladder
program do not function. Before stopping a ladder
program, make sure that the machine state is
normal and that there is no person near the
machine.
2 When an attempt is made to stop the ladder

continue endlessly, depending on the ladder
operation. In such a case, modify the ladder
