Programming Console Operations Section 7-3
7-3-22 Unsigned Decimal Data Modification
This operation is used to change the decimal value of a data area word being
monitored as unsigned decimal data, within a range of 0 to 65,535 (0 to
4,294,967,295 for double-length data). A change into hexadecimal data is
made automatically.
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 on the Output Units may operate unexpectedly.
1,2,3... 1. Monitor (unsigned decimal) the status of the word for which the present
value is to be changed.
(Unsigned decimal monitor)
2. Press the CHG Key to begin decimal data modification.
3. Input the new PV and press the WRITE Key to change the PV. The opera-
tion will end and the decimal-without-sign monitoring display will return
when the WRITE Key is pressed.
The PV can be set within a range of 0 to 65,535 (0 to 4,294,967,295 for
double-length data).
If an error is made, press the CLR Key to restore the status prior to the in-
put. Then enter the correct input.
Note The buzzer will sound if the input value is not within range.
7-3-23 Three-word Data Modification
This operation is used to change the contents of one or more of the 3 consec-
utive words displayed in the Three-word Monitor operation. It is possible in
MONITOR or PROGRAM mode only.
!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 on the Output Units may operate unexpectedly.
