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, 24VDC external power supply voltage drop)
• Within approximately five seconds after the AnyWireASLINK system is powered on or system reset recovery
• While 'Adjustment mode executing flag' (XF) is on
• While 'Parameter access completion flag' (X11) is off
• When automatic address detection is in progress (While 'Automatic address detection flag' (X14) is on)
• When the same address used check is in progress (While 'Overlap address inspection flag' (X15) is on)
• When the easy replacement setting for one slave module is in progress (While One slave module changing flag' (X16) is
off)
• When the parameter access is in progress (While 'Parameter access request command for the slave module' (Y10),
'Parameter batch read command for the slave module' (Y11), or 'Parameter batch write command for the slave module'
(Y12) is on)
• When any of the following errors has occurred

■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
• When enabling easy replacement setting for one slave module
• When changing device parameters of a slave module or restoring data with the data backup/restoration after enabling easy
replacement setting for one slave module
■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 RJ51AW12AL, 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.
■Word slave modules
When the automatic address detection function is executed with a word slave module connected, set the number of word data
points in the parameter setting to 2 words (1 input word/1 output word) or larger. (Page 51 Word data point setting)
If the number of word data points is not set, the address is not stored in the EEPROM of the RJ51AW12AL even when the
automatic address detection function is executed.
