8.2 Function Details
Transmission cable short detection function
This function protects the system by detecting an overcurrent out of the specifications of the AnyWireASLINK and stopping
the transmission.
Transmission cable short status
When the following occurs, the AnyWireASLINK system is in the transmission cable short status.
• The LINK LED turns off and the ALM LED flashes repeatedly at 1 second intervals.
*1
• DP/DN short error (RXn1) turns on.
• 00C9H is stored in Latest error code storage area (RWrn+16).
*1*2
• 0FFFH is stored in Latest error ID storage area (RWrn+17).
*1*2
• The AnyWireASLINK bit transmission stops.
*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 the transmission cable short status
How to recover from the transmission cable short status is as follows.
1.
Eliminate the short-circuit in the AnyWireASLINK system.
When the short-circuit is eliminated, AnyWireASLINK bit transmission is resumed automatically.
If the status does not change, the short-circuit has not been eliminated. Therefore, check the system again.
The following status is maintained:
• ON state of DP/DN short error (RXn1)
• Flashing of the ALM LED
• Data in Latest error code storage area (RWrn+16) and Latest error ID storage area (RWrn+17)
*1
*1 If multiple errors occur simultaneously, the latest error is displayed.
2.
Power off and on the bridge module or turn 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).
The following status is resulted:
• DP/DN short error (RXn1) turns off.
• The ALM LED turns off.
• The data in Latest error code storage area (RWrn+16) and Latest error ID storage area (RWrn+17) is cleared.
