(15)Parameter storage areas (Un\G12288 to Un\G18431)
The parameter of each ID is stored.

When five slave modules are connected, the buffer memory addresses of the parameter storage areas
Ex.
are as follows.
Module
First slave module
Second slave module
Third slave module
Fourth slave module
Fifth slave module
The parameter of the slave module is moved over in order of ID and stored in Parameter storage areas (Un\G12288 to
Un\G18431) after executing the automatic address detection function.
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 slave module later than the ID where the slave module is added or deleted must be changed when
the program is created by directly specifying the buffer memory address. (This also applies if the ID is changed and sorting
order is switched.)
If Parameter storage location memory number (Un\G10496 to Un\G10751, Un\G11008 to Un\G11263) is used, the program
that reads/writes the parameter can be created without considering the addition or deletion of the slave module. ( Page

Description
• 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,
perform the automatic address detection.
