4.10 Address setting (reference)
The
“Address setting” of a slave unit is
determined by which number bit (in order) in the
AnyWireASLINK transmission frame the slave unit is associated with.
Each terminal occupies the location of its own point number (with the set address number placed at
the beginning) from that position.
Addresses can be freely set from
“0 to 254” for both input and output.
Example:
Eight-point terminal: When address is
“0”
Bits
“
0 to 7
”
are occupied in the transmission frame.
Set addresses so as to avoid bit interference.
Example:
The address of a slave unit is processed as a decimal number.
Write the value that you want to set to the slave unit, using a dedicated address writer (ARW-04, ARW-03).
Bit address
“255” or “511,” showing that the address has not been set, is set before shipment.
Address before shipment differs depending on the slave unit.*
Input/output operations are not performed as long as an address before shipment remains
unchanged.
There is no problem if
“255” is included in the occupied numbers.
Example:
Set address
“254” to a two-point occupied terminal, and use “254” and “255.”
It is necessary to be careful that the area which the slave unit occupies does not exceed the setting for the
number of transmission point that is set on the master side.
* For more information, refer to the manual for the slave unit.
