Words SR 253 to SR 255 cannot be changed.
Caution Before changing the contents of I/O memory, be sure that the changes will not
cause equipment to operate unexpectedly or dangerously. In particular, take
care when changing the status of output bits. The PC continues to refresh I/O
bits even if the PC is in PROGRAM mode, so devices connected to output points
may operate unexpectedly.
1, 2, 3... 1. Monitor the status of the desired word according to the procedure described
in 4-2-13 Bit, Digit, Word Monitor. If two or more words are being monitored,
