(2) Automatic update
No special operation is required because data are automatically updated.
To check the parameter information, refer to the corresponding buffer memory address.
(3) Parameter access
The procedure for parameter access is as follows.
(a) To read parameters
1.
Set the access method.
Store 0000
2.
Set the access target module ID.
Store the access target module ID in Parameter access target module ID specification (Un\G10321).
0000 to 00FF
H
0200 to 02FF
H
3.
Turn on and off Parameter access request command for the slave module (Y(n+1)0).
At this time, Parameter access completion flag (X(n+1)1) turns off. When the parameter access is
completed, Parameter access completion flag (X(n+1)1) automatically turns on.
4.
The read parameters are stored in the following location of each ID.
Device parameter in Parameter storage area 1 (Un\G12288 to Un\G12335)
*1 Buffer memory addresses when one slave module is connected. For details, refer to Page 109, Appendix 2 (15).
(b) To write parameters
1.
Set the access method.
Store 0001
2.
Set the access target module ID.
Store the access target module ID in Parameter access target module ID specification (Un\G10321).
0000 to 00FF
H
0200 to 02FF
H
3.
The written parameters are stored in the following location.
Device parameter read/write areas in Parameter storage area 1 (Un\G12288 to Un\G12335)
*1 Buffer memory address when one slave module is connected. For details, refer to Page 109, Appendix 2 (15).
4.
Turn on and off Parameter access request command for the slave module (Y(n+1)0).
At this time, Parameter access completion flag (X(n+1)1) turns off. When the parameter access is
completed, Parameter access completion flag (X(n+1)1) automatically turns on.
5.
Turn on Parameter access request command for the slave module (Y(n+1)0) or Parameter batch
read command for the slave module (Y(n+1)1) to check that the settings have been saved in the
slave module.
