Safety Outputs
Section 5-4
Reflecting Output Data from Output I/O Tags to Safety Output Terminals
Output I/O tag data is reflected in the safety output terminals according to the
channel mode, as shown in the following tables.
X = 0-7
n = even numbers

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.
• The safety output which the error was detected becomes inactive without
depending on the user program.
• The LED indicator of the safety output 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 an error is detected in one of the
two outputs.
• Both outputs to the external device become inactive without depending on
a user program.
• The LED indicator of the safety output terminal with the error lights red,
and LED indicator of the other output flashes red.
• The error appears in the error history.
• The NE1A-series Controller continues to operate.
The following operations are performed if the two outputs from the user pro-
gram to output I/O tags are equivalent.
• Both outputs to the external device become inactive without depending on
a user program.
• The LED indicators of the paired safety output terminals light red.
• The error appears in the error history.
• The NE1A-series Controller continues to operate.
