Our company buy a new machine. It used the LOGO! controller. I'd like to learn the program for our maintenance or troubleshtrooting.  Because I don't have connect cable, so I take the screen picture one by one. 

I'm new for LOGO! controller, therefore I cannot understand some input connector. For example,

1. in picture 163 (see attached picture) ,  the first connector is 107, I don't know what is mean?

continues from the topic.

2. in picture 173 (see attached picture), what is the difference between the first connector "I4" an4d the last connector "In4"? are them same thing?

can somebody help me for these questions?  I will appreciate it!

I have the logo never programmed via the display, only through the software.

But I guess that this is B107.
Inputs only 1-24
Outputs only 1-16

Because the display only allows 3 characters for the display of a block in this view, it is my opinion to B107. It lacks only the "B".

Hello,

Perhaps the following topic might help:

Learn how to use LOGO! 

2. in the picture 173 (see attached picture), what is the difference between the first input "I4" and the last input "In4" ? are them same meaning? 

Can somebody help me for these questions kindly ? I will appreciate it!

Thanks for ixo65, about the first question 107, I think your explanation is make sence.  

How about the "I4" and "In4", are them same?

I look at my logo , it's an 0BA8.

In(x) is the number of the input connector.
In your example is a positive edge with 4 inputs.
Of the 4 inputs of this block, only the first is connected.
In1 is connected with I4.
In2 is not connected.
In3 is not connected.
In4 is not connected.

The "n" after the I said that the input is not connected.

Thank you very much ixo65! 

I think your answer is perfect  to solve my questions. now I can continue my job again.

thanks again to you!
