5Functions set with parameters
(6) Switching to the RAM operation
Use the following procedure (steps [1] to [3]) to switch to the RAM operation.
[1] Prepare to write the information in the ROM area back to the RAM area.
Write the programs and parameters written into the ROM area
when the RAM operation was switched to the ROM operation
back into the RAM area.
At this point, after the information (programs, parameters, val-
ues of common variables, and error logs) in the RAM area is
cleared once, restore processing is performed from the ROM
area.
1) Display the parameter setting screen from the menu
screen.
2) Enter "RESTORE" in the parameter name field, and
press the [EXE] key.
3) When "FLROM->SRAM" is displayed in the data
field, press the [EXE] key again as is.
* Do not change the content of the data field.
Prepare to restore the information back into the
RAM area. At this point, the ALWAYS program does
not stop. When the preparation is complete, the
cursor moves to the parameter name field.
[Cancel Operation]
When the function key corresponding to the
"CLOSE" is pressed then data is not changed.
4) in the data field, press the [EXE] key again. The
cursor moves to the parameter name field.
5) Be sure to shut off the power here. Also, be sure to
shut off the power during [Cancel Operation] in step
3) above. Copy to the RAM area is performed the
next time the power is turned on. If the power is not
shut off after the operation in step 3), data will not be
properly copied into the RAM area.
6) Turn on the power to the controller.
After the power is turned on, "OK" is displayed in
"STATUS NUMBER" on the operation panel. After
verifying that "OK" is displayed, press the [START]
button on the operation panel. (The following page
describes the detail of this operation.)
If the information in the RAM area is restored into the ROM area, all the
contents of the parameters changed during the ROM operation, the values of
common variables, and logs of errors occurred are discarded. If any parameter
was changed during the ROM operation, change the parameter again after
switching to the RAM operation is complete.
