1. After you choose AI as input mode, select the channel by the
Channel combo box.
2. In the Operation area, you can define the input condition opera-
tion. Select the analog input type by the Type combo box. There
are two input types you can choose for analog input: If you select
ChannelValue, the current value of the selected analog input chan-
nel is used as input for condition. If you select Deviation, the devi-
ation (Dividing difference between present sample value and
previous sample value by the total range value) of the selected ana-
log input channel is used as input for condition.
3. Select the appropriate condition for that input channel by the Con-
dition combo box and the Value text box. Refer to the examples in
the table below to see how to define analog input condition:
The analog input will read voltage (or current) from the channel we spec-
ified. Usually, the voltage (or current) value can represent the real-world
Channel Type Condition Value Description
0 Channel-
Value >= 5 If the value of analog channel
0 is more than or equal to 5,
the condition result is logic
True. Otherwise, the condition
result is logic False.
2 Channel-
Value = 3.2 If the value of analog channel
2 equals to 3.2, the condition
result is logic True. Other-
wise, the condition result is
logic False.
3 Channel-
Value <= 1.7 If the value of analog channel
3 is less than or equal to 1.7,
the condition result is logic
True. Otherwise, the condition
result is logic False.
5 Deviation N/A 20 If the deviation of analog chan-
nel 5 is greater than 20%, the
condition result is logic True.
Otherwise, the condition result
is logic False.
