9. WRITING TO/READING OF/VERIFICATION OF POSITIONING
MODULE DATA
9.1 Write to Module/Read from Module/Verify Module Data
PURPOS
E
Write, read and verify the data set in the project (parameters, servo parameters,
positioning data, block start data) on an axis by axis basis.
• Write to module executes a write to the QD75/LD75/LD77 which is set in the active
project. When performing batch write to multiple QD75/LD75/LD77s, use the multi-
module batch write function. (Refer to Section 11.1.4)
Note that data cannot be batch-written simultaneously to the positioning module of
MELSEC-Q series and that of MELSEC-L series on the same route.
• Whether write to module may be performed or not is determined by the PLC state
check setting in Option setting. (Refer to Section 11.5)
• When trying operation while simultaneously changing the positioning data, you can
use the positioning data test edit function to write only the positioning data during a
test. (Refer to Section 11.7.2)
BASIC OPERATIO
N
1. Place the QCPU/LCPU in the STOP status.
When performing write to QD75/LD75/LD77 without putting the QCPU/LCPU in
the STOP status, change the PLC state check setting in Option setting.
2. As an active project, set the project used for write to QD75/LD75/LD77/read
from QD75/LD75/LD77/verify QD75/LD75/LD77 data. Refer to Section 5.2 for
the active project setting.
3. Click the [Online]
[Write to module] (
)/[Read from module] (
)/Verify
module data] (
) menu.
4. Set the data type and range in the Write to module/ Read from module/Verify
module data dialog box.
5. Click the "OK" button to start operation.
6. For module data verify, the verify result appears.
