Precautions
■Situations in which automatic address detection cannot be executed
Automatic address detection cannot be executed in the following cases.
• When an error occurs in the AnyWireASLINK system (Example: Short circuit, 24 V DC external power supply voltage drop)
• Within approximately five seconds after the AnyWireASLINK system is powered on or CPU module reset recovery
• When automatic address detection is in progress (While 'Automatic address detection flag' (Un\G28 b11) is on)
• When the same address used check is in progress (While 'Overlap address inspection flag' (Un\G28 b12) is on)
• When the parameter access is in progress (While 'Parameter access request command for the slave module' (Un\G27 b8),
'Parameter batch read command for the slave module' (Un\G27 b9), or 'Parameter batch write command for the slave
module' (Un\G27 b10) is on)
• When any of the following errors has occurred

0CC8H
0CC9H

1867H
3064H
3065H
3066H
■Situations in which automatic address detection is required
Execute automatic address detection in the following cases.
• When starting the system operation (when all of the slave modules are connected and operating normally)
• When adding a slave module after starting the system operation
• When removing a slave module after starting the system operation
• When changing the address of a slave module after starting the system operation
■Check after execution of automatic address detection
After executing automatic address detection, check that there is no inconsistency between the actual system configuration
and the IDs registered in the FX5-ASL-M, referring to the value stored in 'Number of the IDs of the connected modules'
(Un\G9216) and values stored in 'Connected module ID information storage area' (Un\G9217 to Un\G9344).
■Executing automatic address detection again
Use an address writer to set the ID (address) in a slave module that has the same ID as other slave modules or where an ID
is not set. Then execute automatic address detection again.
■When non-processing is executed even after automatic address detection is executed
Do not execute automatic address detection in any of the following cases. Automatic address detection is not processed if
executed.
• When 'Parameter access completion flag' (Un\G28 b9) is off
• When 'Automatic address detection flag' (Un\G28 b11) is on
Create an interlock program to ensure proper execution of automatic address detection.
For the interlock program of automatic address detection, refer to the following.
