Safety Inputs
Section 5-2
IMPORTANT
Both input ON delays and OFF delays must be added to the I/O response per-
formance. This will affect the safety distance calculation.
For further details, refer to
Section 9 Remote I/O Communications Perfor-
mance and Local I/O Response Time
.

Dual Channel Mode Setting
An NE1A-series Controller’s local safety input terminals can be set to Dual
Channel Mode. Setting Dual Channel Mode enables the following.
• The status of the two inputs can be evaluated and reflected in I/O tags .
• The discrepancy time between changes in the status of the two inputs can
be evaluated.
Reflecting Input Status in Input I/O Tags
The status input to the safety input terminals is reflected in the I/O tags
according to the channel mode as shown in the following tables.
X = 0 to 15 (NE1A-SCPU01(-V1))
X = 0 to 39 (NE1A-SCPU02)
n = Even number
Input Discrepancy Time Evaluation
For two inputs set in Dual Channel Mode, the time is monitored from a change
in the value of one input to a change in the value of the other input (discrep-
ancy time ). When the value of the other input does not change within the set
discrepancy, it is regarded as an error. The set discrepancy time can be set in
increments of 10 ms between 0 (invalid) and 65,530 ms.
The discrepancy time cannot be set in Single Channel Mode.
