(3) Precautions
(a) The automatic address detection cannot be performed in the following cases.
• Upon an error 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
• Automatic address detection or parameter access by Y(n+1)0 to Y(n+1)2 is in progress.
• When any of the following errors has occurred
0064H
0065H
0067H
00C8H
00C9H
(b) Perform the 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
(c) After performing the automatic address detection, check that there is no
inconsistency between the actual system configuration and the IDs registered in the
master module, 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
areas (Un\G9217 to Un\G9344).
(d) 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.
(e) Do not perform the automatic address detection in any of the following cases. If
executed, the automatic address detection is not processed.
• When Parameter access completion flag (X(n+1)1) is off
• When Automatic address detection flag (X(n+1)4) is on
