Chapter 9 Monitoring Function; Automatic Address Detection; Performing The Automatic Address Detection - Mitsubishi Electric CC-Link-AnyWire Bitty Bridge User Manual

CHAPTER 9
The slave module of AnyWire Bitty has a specific ID (address). When the NZ2AW1C1BY sends an ID (address), the
disconnection and the existence of slave modules are detected by receiving a reply from the slave module having the
corresponding ID (address).
The NZ2AW1C1BY uses the automatic address detection operation to store the addresses of the currently connected
slave modules in the EEPROM.
This information is stored even when the power is turned off.
Then registered IDs (addresses) are sent in order. If the slave module does not reply, the LINK LED notifies of the
disconnection.
9.1

Automatic Address Detection

Automatic address detection is a function to store the ID (address) of the connected slave module in the EEPROM of
the NZ2AW1C1BY.
Perform the automatic address detection in the following cases.
• When starting system operation with all the slave modules connected to the bridge module
• When adding a slave module
• When deleting a slave module
• When changing the address of a slave module
9.1.1

Performing the automatic address detection

Use the SET switch to perform the automatic address detection.
Procedure
1.
Check that all of the slave modules are operating normally.
2.
Keep pressing the SET switch until the SET LED (orange) turns on.
3.
When the SET LED turns on, flashes, and turns off, the ID (address)
has been stored.
● During automatic address detection, input or output may not be accepted. Perform automatic address detection in the
status that does not affect the operation of the equipment, such as while the program execution of the programmable
controller is being stopped.
● When an error such as a short circuit occurs in the AnyWire Bitty bridge module, or for approximately five seconds after
the module is turned on or reset, the automatic address detection cannot be performed.
● Do not perform the automatic address detection when a disconnection error has occurred while in operation. Otherwise,
disconnection information may be lost.
