4.10 Address setting (reference)
The
“Address setting” of a slave unit
determines from what number of bit in AnyWireASLINK
transmission frame each slave unit is associated.
Each terminal occupies its own number of points from that position (starting from a preset
address No.).
The address number can be freely set in a range of 0 to 254 for input and output each.
Example)
8 point terminal: When address is
“0”
“0 to 7 bits” are occupied in transmission frame.
Set address so as to avoid bit interference.
Example)
Address of slave unit is handled by decimal number.
The value to be set shall be written in the slave unit by using a dedicated address writer (ARW-04 or
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 2 point occupied terminal and use “254” and “255.”
It is necessary to take into consideration so that the area which the slave unit occupies does not
exceed the transmission I/O setting set on the master side.
* For more information, refer to the manual for the slave unit.
