Single/Dual
Set the evaluation method to use with the safety input terminals.
Setting Description
Single Channel The safety input terminals are used as independent safety input terminals.
Dual Channel Equivalent The safety input terminals are used as dual-channel-equivalent inputs.
Dual Channel Complementary The safety input terminals are used as dual-channel-complementary inputs.
Safety Mat/Safety Edge The safety input terminals are used as safety mat/safety edge inputs.
l
Discrepancy Time
For two inputs set in a 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. An error occurs if the value of the other input does
not change within the set discrepancy time.
The discrepancy time can be set to any of the following eight values between 500 ms and 64,000
ms.
1: 500 [ms], 2: 1000 [ms], 3: 2000 [ms], 4: 4000 [ms], 5: 8000 [ms], 6: 16000 [ms], 7: 32000
[ms], 8: 64000 [ms]
The discrepancy time cannot be set in Single Channel Mode.
l
Relationship between the Single/Dual Setting and Safety Input Data
The signals that are input to safety input terminals are evaluated as shown in the following table.
This safety input data can be used in the safety program in the Safety CPU Unit.
