■
Buffer memory address
The following shows the buffer memory address of this area.
Module information [FX2N Allocation Mode]
The FX5-8AD module information in FX2N allocation mode function is stored. For model information, 61E4H (fixed
hexadecimal value) is stored.
■
Buffer memory address
The following shows the buffer memory address of this area.

■
Buffer memory address
The following shows the buffer memory address of this area.
Warning output flag (Process alarm upper limit)
The upper limit alarm of the process alarm can be checked for each channel.
■
Buffer memory address
The following shows the buffer memory address of this area.
■
Alert output flag status
• If the limit specified by the process alarm upper upper limit value is equal to or exceeded, Alarm ON (1) is stored in 'Alert
output flag (Process alarm upper limit)' (Un\G36) of the corresponding channel.
• If an alert is detected even in one channel, of the channels where conversion is enabled and the alert output setting
(Process alarm) is enabled, 'Alert output signal' (Un\G69, b8) also turns on.
■
Clearing Alert output flag
• When the digital operation value becomes smaller than the process alarm upper lower limit value, the flag is automatically
cleared.
• Turning off → on → off 'Operating condition setting request' (Un\G70, b9) allows the flag to be cleared.
