4-2-24 Unsigned Decimal Data Modification
This operation is used to change the decimal value of a word being moni-
tored as unsigned decimal data. A change into hexadecimal data is made
automatically.
Words SR 253 to SR 255 cannot be changed.
RUN MONITOR PROGRAM
No OK OK
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 (unsigned decimal) the status of the word for which the present val-
ue is to be changed.
