I am new to this stuff sorry about the lack of info. I can say I am using a 5000 series software from RS Logix, and I will try your suggestion tomorrow. Thanks for the help I wonder if its a programming issue instead of communciation I was disucussing this with a colleague who seems to think its...

I currently have RS Logix set up with a ladder logic program, when I force inputs from RS Logix I can get it to update the Red Lion G310 HMI. However, I cannot press a button, that I have made via crimson 3.0 on the G310 HMI and have it send to RS Logix. For example if I press a button that I...

So should this be simplified further?

Posted this with my phone sorry if it is hard to read

Is my answer improved at all?

Sorry if the post is a bit confusing and my slow responses.

What did you use for u? I guess you did a u substitution to do this then so if I find u I can do the derivative.

Find the optimum frame length nf that maximizes transmission efficiency for a channel with random bit erros by taking the derivative and setting it to zero for the following protocols: (a) Stop-and-Wait ARQ (b) Go-Back-N ARQ (c) Selective Repeat ARQ My work has been uploaded I am a bit rusty on...

Sorry was my question out of line? If so we can go back to the original, I just figured this was a better starting point.

Ok so I found a question in my book that may be a better example to start with. I UPLOADED WORK. It states: This problem provides a numerical example of encryption using a one-round version of DES. We start with the same bit pattern for the key K and the plaintext, namely: Hexadecimal...

Is there no way to do this by hand? If not I would have to guess Excel?

I don't think I am using the correct tables because I looked up a table on Wikipedia that had the stuff in binary. But I am still unsure of what the outer and inner bits are?

Homework Statement example: S(18 09 12 3d 11 17 38 39) = 5fd25e03 Homework Equations The Attempt at a Solution So I know about DES that you split a 64 bit block into left and right halves 32 bits each. Where even bits are on the left and odd are on the right. Perform the round...

Ok thanks this clears it up
