4.5 Same ID Used Detection Function
4.5
Same ID Used Detection Function
This function checks whether the same ID is used for multiple slave modules through automatic address detection or same
address used check. The LEDs of the relevant slave modules are forcibly turned on.
• ID duplications are detected through automatic address detection or same address used check. If the CPU
module is reset or the power is turned off after ID duplication detection, the same ID used status cannot be
checked until automatic address detection or same address used check is executed again.
• Even if an ID is assigned to multiple modules, a single ID is stored in 'Number of the alarm IDs' (Un\G9984)
and 'Alarm ID information storage area' (Un\G9985 to Un\G10112). For example, even when multiple
modules have an ID 10, "1" is stored in 'Number of the alarm IDs' (Un\G9984) and "10" is stored in 'Alarm ID
information storage area' (Un\G9985 to Un\G10112).
How to execute automatic address detection
For details on automatic address detection, refer to the following.
Page 55 Automatic Address Detection Function
How to execute same address used check
Turn off and on 'Overlap address inspection command' (Un\G27 b2). If 'Overlap address inspection flag' (Un\G28 b12) turns
on and off, it indicates that the same address used check is completed.
The same address used check cannot be executed under any of the following conditions.
• 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 system is reset
• 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
How to check the same ID used status
When the AnyWireASLINK system is in the following status, the same ID is used for multiple modules.
Even in the same ID used status, the AnyWireASLINK bit transmission does not stop.
• 'Slave module alarm signal' (Un\G28 b8) turns on.
• Same ID used error (error code: 0D90H) is stored in 'Latest error code storage area' (Un\G10256) and the duplicate ID is
stored in 'Latest error ID storage area' (Un\G10257).
*1
• The relevant ID is stored in 'Alarm ID information storage area' (Un\G9985 to Un\G10112).
*1 If multiple errors occur simultaneously, the latest error is displayed.
