Number of the connected modules
■Number of the connected modules (Un\G8960)
This buffer memory area stores the number of slave modules detected by automatic address detection. (Up to 128 modules)
Number of the IDs of the connected modules
■Number of the IDs of the connected modules (Un\G9216)
This buffer memory area stores the number of IDs of the connected modules through automatic address detection. (Up to 128
IDs)
The number of stored IDs is retained even after the power supply is turned off.
Data update timing
The data are updated at the time of power-on or automatic address detection.
Connected module ID information storage area
■Connected module ID information storage area (Un\G9217 to Un\G9344)
This buffer memory area stores the ID information of all the slave modules connected to the FX5-ASL-M in the ascending
order.
The IDs to be stored are as follows.
• 0000H to 00FFH: ID of an output slave module
• 0200H to 02FFH: ID of an input slave module or I/O combined slave module
Information of a stored ID is retained even after the power supply is turned off.
Data update timing
The data are updated at the time of power-on or automatic address detection.
Number of the alarm IDs
■Number of the alarm IDs (Un\G9984)
When a status error occurs in a slave module or an ID or parameter setting error regarding a slave module occurs, this buffer
memory area stores the number of IDs relevant to alarm occurrence. (Up to 128 IDs)
The stored values are retained until the power is turned off and on or 'Error flag clear command' (Un\G27 b0) 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.
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 00FFH: ID of an output slave module
• 0200H to 02FFH: ID of an input slave module or I/O combined slave module
The stored values are retained until the power is turned off and on or 'Error flag clear command' (Un\G27 b0) 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.
