Alarm ID information storage area
■Alarm ID information storage area (Un\G9985 to Un\G10112)
This buffer memory area stores the ID information of all the slave modules where an alarm has occurred in the ascending
order.
The IDs to be stored are as follows.
• 0000H to 00FEH: ID of a bit output slave module
• 0200H to 02FEH: ID of a bit input slave module or bit I/O combined slave module
• 0400H to 05FEH: ID of a word output slave module
• 0600H to 07FEH: ID of a word input slave module or word I/O combined slave module
• 00FFH: Unset IDs of bit output slave modules and word output slave modules
• 02FFH: Unset IDs of bit input slave modules and word input slave modules
The stored values are retained until the power is turned off and on or 'Error flag clear command' (Y0) is turned off and on after
the error is cleared.
Data update timing
The data are updated when the power is turned on or when an alarm has occurred after automatic address detection.
Latest error code storage area
■Latest error code storage area (Un\G10256)
This buffer memory area stores the latest error code detected in the RJ51AW12AL. For details on the error codes, refer to the
following.
