■To write parameters
1.
Read the parameters referring to the procedure in "To read parameters" or "Parameter batch read".
Before executing parameter write, read the parameters of all slave modules of which IDs have been registered.
*1 Because parameter write updates all parameters of target slave modules, all parameters to which no changes are made need to be set
correctly.
Executing parameter write without executing parameter read will result in a malfunction.
2.
Set the access method.
Store 0001H (write) in 'Parameter access setting' (Un\G10320).
3.
Set the access target ID.
Store the access target ID in 'Parameter access target module ID specification' (Un\G10321).
ID
0000H to 00FEH
0200H to 02FEH
0400H to 05FEH
0600H to 07FEH
4.
Store the parameters to be written in the following location.
Device parameter read/write areas in 'Parameter storage area' (Un\G12288 to Un\G12335)
*1 Buffer memory addresses when one slave module is connected. For details, refer to the following.

5.
Turn off and on 'Parameter access request command for the slave module' (Y10).
At this time, 'Parameter access completion flag' (X11) turns off. In addition, 'Parameter accessing flag (with handshake)' (XB)
turns on.
6.
When the parameter access is completed, 'Parameter access completion flag' (X11) automatically turns on.
7.
Turn on and off 'Parameter access request command for the slave module' (Y10).
8.
When 'Parameter access completion flag' (X11) turns on and the following signals are turned off, 'Parameter accessing
flag (with handshake)' (XB) turns off.
• 'Parameter access request command for the slave module' (Y10)
• 'Parameter batch read command for the slave module' (Y11)
• 'Parameter batch write command for the slave module' (Y12)
9.
After executing parameter write, read the parameters of the slave module referring to the procedure in "To read
parameters" or "Parameter batch read" to check that the parameters have been correctly applied to the slave modules.
Description
