POINT
For modules of hardware version "C" or earlier, excessively large (or small) data
may be temporarily read out when a module reads a digital output value from the
PLC CPU.
To prevent this, refer to Appendix 3 and incorporate a sequence program for
ignoring illegal data into the original program.
For modules of hardware version "D" or later, such excessively large (or small) data
may not be read out.
