4-2-23 Signed Decimal Data Modification
This operation is used to change the decimal value of a word being moni-
tored as signed decimal data. The contents of the specified word are con-
verted automatically to signed hexadecimal (two’s complement format).
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.

is to be changed.
