Parameter batch read
The procedure for parameter batch read is as follows.
1.
Turn on and off 'Parameter batch read command for the slave module' (Un\G27 b9).
At this time, 'Parameter access completion flag' (Un\G28 b9) turns off. When the parameter access is completed, 'Parameter
access completion flag' (Un\G28 b9) automatically turns on.
2.
The read parameters are stored in the following location of each ID.
Device parameter in 'Parameter storage area' (Un\G12288 to Un\G12335)
*1
*1 Buffer memory addresses when one slave module is connected. For details, refer to the following.

Parameter batch write
The operating procedure for parameter batch write is as follows.
1.
Before executing parameter batch write, read parameters of all ID registered slave modules according to the procedure
of "Parameter batch read".
*1
*1 Since all the parameters of the target slave module are updated at the time of writing parameters, all the parameters, including the
parameters of the changed part, must be set correctly.
If writing parameters is executed without reading parameters, it may cause malfunction.
2.
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
*1 Buffer memory addresses when one slave module is connected. For details, refer to the following.

3.
Turn on and off 'Parameter batch write command for the slave module' (Un\G27 b10).
At this time, 'Parameter access completion flag' (Un\G28 b9) turns off. When the parameter access is completed, 'Parameter
access completion flag' (Un\G28 b9) automatically turns on.
4.
After executing parameter batch write, check that the setting have been saved in the slave module by reading
parameters in the slave module according to the procedure of "To read parameters", or "Parameter batch read".
• During the parameter access, parameter batch read, and parameter batch write, 'Parameter access
completion flag' (Un\G28 b9) is off. When 'Parameter access completion flag' (Un\G28 b9) is off, the
parameter access, parameter batch read, and parameter batch write cannot be executed.
• Upon parameter batch read or parameter batch write, the values stored in 'Parameter access setting'
(Un\G10320) and 'Parameter access target module ID specification' (Un\G10321) are ignored.
• The buffer memory areas Un\G10496 to Un\G10751 store the start address of the buffer memory area that
stores parameters of output slave modules with the IDs. The 48 words from the buffer memory start address
is the parameter information of each ID.
• The buffer memory areas Un\G11008 to Un\G11263 store the start address of the buffer memory area that
stores parameters of input slave modules or I/O combined slave modules with the IDs. The 48 words from
the buffer memory start address is the parameter information of each ID.
