Error Handling
Behavior on Error Detection
Behavior in Single Channel Mode
The following operations are performed if an error is detected during self-diag-
nosis.
• I/O tags corresponding to safety input terminals for which errors have
been
detected are made inactive.
• The LED indicator of the safety input terminal with the error lights red.
• The error appears in the error history.
• The NE1A-series Controller continues to operate.
Behavior in Dual Channel Mode
The following operations are performed if a discrepancy error is detected.
• I/O tags corresponding to safety input terminal pairs for which errors have
been detected are made inactive.
• Both LED indicators of the safety input terminals with the error light red.
• The errors appear in the error history.
• The NE1A-series Controller continues to operate.
The following operations are performed if an error is detected in one of the
two inputs.
• I/O tags corresponding to safety input terminal pairs for which errors have
been detected are made inactive.
• The LED indicator of the safety input with the error lights red, and the LED
indicator of the other input flashes red.
• The errors appear in the error history.
• The NE1A-series Controller continues to operate.
Error Latch Time Setting
The time to latch the error state when an error occurs in a safety input circuit
can be set. The error state will continue until the error latch time passes even
if the cause of the error is momentarily removed. When monitoring errors from
a monitoring system, take the monitoring interval into account when setting
the error latch time.
The error latch time can be set in increments of 10 ms between 0 and 65,530
ms. The default is 1,000 ms.
Resetting Errors
All conditions below are necessary to recover from an error that has occurred
in a safety input.
• The cause of the error must be removed.
• The error latch time must have passed.
• The input signal must return to an inactive state and there must be no
error condition detected. (e.g., by pressing the emergency stop button or
opening a door).
