Online Edit
Before starting the online edit using WindLDR, download a user program to the CPU module or upload a user program
from the CPU module using the ordinary program download or upload. If user programs do not match between WindLDR
and the CPU module, the online edit cannot be used.
Online edit can not change Function Area Settings and Expansion Data Register values. Only ladder diagrams can be
edited.
When TIM/CNT preset values have been changed as a result of advanced instructions or through communication, con-
firm or clear the changes before starting the online edit. See page 7-18.
If you do not want to clear the new preset values during the run-time program download or test program download, you
can import the new preset values to the user program. Access the PLC Status dialog box from the Online menu in the
monitoring mode. Then click the
Confirm
button in the TIM/CNT Change Status field. (The displayed status will switch
from
Changed
to
Unchanged
.) Upload the user program, which has new preset values in place of the original preset val-
ues. Make changes to the uploaded user program, then perform the run-time program download or test program down-
load. Note that the
Confirm
button has effect on both timer and counter preset values.
Note:
When “Enable D10000 to D49999” has been selected in the Function Area Settings for the slim type CPU module, the online edit
cannot be used. To use the online edit, deselect the use of extra data registers D10000 to D49999. See page 6-2.
