Interrupt factor detection flag [n]
The detection status of the interrupt factor is stored.
Monitor value
0
1
When an interrupt factor occurs, an interrupt request is sent to the CPU module at the same time as 'Interrupt factor detection
flag [n]' (Un\G4 to Un\G19) turns to Interrupt factor (1).
"n" indicates an interrupt setting number. (n = 1 to 16)

Alert output flag (Process alarm upper limit)
The upper limit alarm of the process alarm can be checked for each channel.

Alert output flag (Process alarm upper limit)
■Alert output flag status
• If the limit specified by the process alarm upper upper limit value is 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' (XD) also turns on.
■Clearing Alert output flag
• As the measured temperature value returns to the setting range, the flag is automatically cleared.
• Turning on and off 'Operating condition setting request' (Y9) allows the flag to be cleared.
