Automatic Address Detection Function
Automatic address detection refers to a function that stores the IDs (addresses) of the connected slave modules in the non-
volatile memory of the NZ2AW1GNAL.
When Automatic address detection command (RY1) is operated or the SET switch on the NZ2AW1GNAL is pressed, the
NZ2AW1GNAL detects and stores the ID (address) of the connected slave module.
The ID (address) information stored in the non-volatile memory is held even when the module is powered off. However, the
parameter information of the same ID information is not held.
Whenever starting the system or changing the system configuration, set the correct addresses to all the slave modules and
perform the automatic address detection.
Performing the automatic address detection mode
Automatic address detection has two modes of operation: normal mode and high-speed mode.
The operation mode is automatically selected by the NZ2AW1GNAL.
To see which operation mode the automatic address detection is in, check Automatic address detection operation mode
(RX18).
Normal mode
In this mode, automatic address detection is executed without stopping AnyWireASLINK bit data transmission and word data
transmission. Automatic address detection can be executed even while the system is running, but the process takes longer to
complete.
High-speed mode
In this mode, AnyWireASLINK bit data transmission and word data transmission are stopped before automatic address
detection is executed. There is a need to stop the system at the time execution, but automatic address detection is executed
at high speed.
■
High-speed mode execution conditions
The system will automatically change to high-speed mode when all of the following conditions are met.
• If either the CPU is in the STOP state, CC-Link IE TSN is disconnected, or cyclic transmission is stopped for CC-Link IE
TSN
• If the "Output data hold/clear setting" setting in "Network Configuration Settings" of "Basic Settings" of the master station is
set to "0: CLEAR"
Once the automatic address detection function starts in high-speed mode, that state will be maintained even when one of the
conditions above becomes invalid during execution. AnyWireASLINK bit data transmission and word data transmission will
also remain stopped. After the automatic address detection is completed, bit data transmission and word data transmission
will restart.
