Appendix 4 Buffer Memory
Parameter storage area
This buffer memory area stores parameters for slave modules with IDs.
■
Parameter storage area (Un\G12288 to Un\G18431)
Ex.
When five slave modules are connected, the buffer memory addresses of the parameter storage areas are as follows.
The parameter of the slave module is moved over in order of ID and stored in 'Parameter storage area'
(Un\G12288 to Un\G18431) after the automatic address detection function is executed.
Because of this, the address of the parameter storage area for the slave module later than the ID where the
slave module is added or deleted in the AnyWireASLINK system is changed. (The parameter of a non-existing
ID is deleted and displayed.)
Therefore, the address of the slave module later than the ID where the slave module is added or deleted must
be changed when a program is created with buffer memory addresses directly specified. (This also applies if
the ID is changed and sorting order is switched.)
With 'Parameter storage location memory number (output)' (Un\G10496 to Un\G10751) or 'Parameter storage
location memory number (input)' (Un\G11008 to Un\G11263), a program that reads/writes the parameter can
be created without considering the addition or deletion of slave modules.
Address Description Details
Un\G12288 to Un\G12335 Parameter storage area 1 (48 words) • The parameter storage area of each ID has 48 words.
• Information of up to 128 parameters can be stored.
• The ID is stored in the start address of each parameter area.
• A single storage area has 48 words and the data are sorted in the
ascending order of IDs.
• When adding a slave module or changing the ID of a slave module,
execute automatic address detection again.
