(1) 0: Normal, 1: Alarm ON
(2) The values of b4 to b15 are fixed to 0.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
Warning output flag (Process alarm upper limit)
■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 returns within the setting range, the flag is automatically cleared.
• Turning offonoff 'Operating condition setting request' (Un\G70, b9) allows the flag to be cleared.
Warning output flag (Process alarm lower limit)
The lower limit alarm of the process alarm can be checked for each channel.

■Alert output flag status
• If the limit specified by the process alarm lower lower limit value is equal to or exceeded, Alarm ON (1) is stored in 'Alert
