WARNING
1 You have to pay special attention to use Forced I/O
function to change status of signals. Inappropriate use of
Forced I/O function may cause unexpected reaction of
machine. You have to make it sure that nobody is near
the machine when you use this function.
2 As you use Forcing mode of Forced I/O function to
change status of signal, however, the signal may look
proof against Forced I/O function, because LADDER
program or I/O device writes into the signal repeatedly. In
this case, even if the signal looks unchanged, actual
signal may be changed in very short moment. You
should be careful for the reaction of machine to such
signal changes.
