Address Inspection Function - Mitsubishi Electric AnyWire ASLINK User Manual

Address Inspection Function

This function executes an address inspection to detect a slave module having no ID or a slave module having a duplicate ID.
• If the NZ2AW1GNAL is reset or the power supply is turned off after the no ID setting status and ID
duplication are detected, the no ID number setting status and ID duplication status cannot be checked until
automatic address detection and address inspection are performed again. Execute the address automatic
detection and the address inspection command operations again.
• If the same ID is set for multiple slave modules, a single ID is stored in Number of the alarm IDs (RWr8) and
Alarm ID information storage area (5500H to 55FFH). For example, even when multiple modules have an ID
000AH, "1" is stored in Number of the alarm IDs (RWr8) and "000AH" is stored in Alarm ID information
storage area (5500H to 55FFH).
• Even if no ID number is set or the ID is duplicated, bit transmission and word transmission do not stop.
However, the operation of the NZ2AW1GNAL and slave modules is not guaranteed in the ID duplication
state.
How to execute the address inspection
1.
Turn on Address inspection command (RY2). Address inspection will start.
2.
Confirm that Address inspection flag (RX15) turns on, and turn off Address inspection command (RY2).
3.
When Address inspection flag (RX15) turns off, the address inspection is completed.

• Remote READY (RX0) is off.
• Adjustment mode flag (RXF) is on.
• Parameter access completion flag (RX11) is off.
• Automatic address detection is in progress. (Automatic address detection flag (RX14) is on.)
