Parameter access error detection function
Detects errors that occur during reading or writing of the parameters of a slave module. The following parameter access errors
are detected.
• Slave module hardware error (Error code: 012CH, 012DH)
• Parameter access target module ID error (Error code: 012EH)
• Parameter value error (Error code: 012FH)
• Parameter access error (Error code: 0130H)
• Slave module status error (Error code: 0131H)
• Same ID used error (Error code: 0190H)
• No ID setting error (Error code: 0191H)
How to check the parameter access error status
The following table lists parameter access error statuses.
*1 If multiple errors occur simultaneously, the latest error is displayed.
How to recover from the parameter access error status
How to recover from the parameter access error status is as follows.

How to recover from a slave module hardware error
1.
Eliminate the error cause by taking measures such as noise prevention.
Even when Slave module hardware error is cleared, the following status is maintained.
• ON state of Slave module alarm signal (RX(n+1)0)
• The error code stored in Latest error code storage area (RWrn+16)
*1*2
• The error ID stored in Latest error ID storage area (RWrn+17)
*1*2
• The unset ID (02FFH or 00FFH) stored in Latest error ID simple information (RXn6 to RXnF)
*1
• The alarm information 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.
2.
Power off and on the AnyWireASLINK system or turn on and off Error reset request flag (RY(n+D)A).
The following status is resulted:
• Slave module alarm signal (RX(n+1)0) turns off.
• The value in Latest error code storage area (RWrn+16) is cleared.
• The value in Latest error ID storage area (RWrn+17) is cleared.
• The value in Latest error ID simple information (RXn6 to RXnF) is cleared.
• The alarm information that was notified to the device of the CPU module is cleared.
