3.5 Operation Processing during Momentary Power Failure

SEQUENCE PROGRAM EXECUTION

3.5 Operation Processing during Momentary Power Failure

When the input voltage supplied to the power supply module drops below the specified
range, the CPU module detects a momentary power failure and performs the following
operation.

(1) When momentary power failure occurs for a period shorter than the

permitted power failure time

The output is maintained when the momentary power failure occurs, and error history
are logged. Then the system interrupts the operation processing.
(The timer clock continues.)

(a) When recovered from momentary power failure

When a momentary power failure ends, the operation processing is resumed.

(b) Watchdog timer (WDT) measurement during momentary power failure

Even if the operation is interrupted due to momentary power failure, the watchdog
timer (WDT) measurement continues. For example, if the GX Developer PLC
parameter mode WDT setting is set at 200 ms, when a momentary power failure
of 15 ms occurs at scan time 190 ms, the watchdog timer error is set.

(2) When momentary power failure occurs for a period longer than the

permitted power failure time

CPU module starts initially.
The same operation processing as that after the following operation occurs.

• Power ON
• Resetting using RUN/STOP/RESET switch.
• Remote setting using GX Developer
