Write the above procedures, enter 2 of the input can not read, but the input 2 changed to enter 3, you can read. Please guide.

Can you put a ladder diagram on it?

What do you mean by enter 2 and enter 3? Analog acquisition is not normal acquisition it?
Are the 3 and 4 channels placed in the program, DM0 and DM1 collected, and are the analog inputs laid out for the passage?

Analog acquisition can not be normal acquisition, but the input of two analog signals, changed to the input after 3 can be collected, of course, the channel settings are also required to enter 2, change 3. As long as you can collect procedures, you can perform
