8.2 Function Details
Same ID number used detection function
ID duplication in all the connected slave modules is detected by performing the automatic address detection.
• If the AnyWireASLINK system is powered off after ID duplication is detected, the ID duplication status
cannot be checked until the automatic address detection is performed again.
• Only one ID is stored in the alarm information that is notified to the device of the CPU module due to ID
duplication. For example, if "000AH" is set to multiple IDs, the value stored in the ID information is "1" and
"000AH" is stored in the alarm ID.
Same ID number used status
When the system is in the following status, the same ID is used for multiple modules.
Even in the same ID number used status, the AnyWireASLINK bit transmission is not stopped.
• Slave module alarm signal (RX(n+1)0) turns on.
• 0190H is stored in Latest error code storage area (RWrn+16).
*1*2
• The duplicated ID is stored in Latest error ID storage area (RWrn+17).
*1*2
• The duplicated ID is stored in Latest error ID simple information (RXn6 to RXnF).
*1
• The duplicated ID is stored in the alarm information notified from the bridge module.
*1*2
• The duplicated ID is notified from the bridge module to the device of the CPU module.
*2
*1 If multiple errors occur simultaneously, the latest error is displayed.
*2 This applies only when the CC-Link operation mode is Ver.2.00.
How to recover from Same ID number used status
How to recover from Same ID number used status is as follows.
1.
Locate the error ID by checking the alarm information that was notified to the device of the CPU module.
2.
Check the ID (address) setting of the slave module and set a unique address in the slave module.
3.
Execute the automatic address detection function of the bridge module.
While an ID (address) is used for multiple slave modules, executing either of the following can eliminate the
same ID used error. However, the address is still used for the multiple slave modules.
• Powering off and on the AnyWireASLINK system
• Turning on and off Error reset request flag (RY(n+1)A, RY(n+3)A, RY(n+5)A, RY(n+7)A, RY(n+D)A)
