Thanks for the reply Dave. I just tried the Use run idle check boxes without a different result. As far as the Configuration Assembly instance #, I had in there 1 originally. I have tried some different numbers for the heck of it, but still no connection that stays. I got my instance values from a project I recently did, but in studio 5k (AB/Rockwell). Do you know why it would be different? I realize now how spoiled I am with being able to upload the EDS files....

Hello,
I am looking for help with ethernet/ip on a unistream 7". I am intermittently connecting to a Mettler Toledo scale. It will connect very quickly and immediately disconnect. I have attached pictures of the eip scanner node struct tags for both scenarios. I have also attached my program. I have looked at multiple scanner eip samples and followed the unitronics ethernet/ip video on youtube. I have still not had any luck keeping a connection. I am not getting any error on the scale controller either. Any help would be greatly appreciated. Thank you in advance.

I'm sorry for not replying. I usually get an email letting me know someone responded. I did not receive any this time. If you anyone is still out there..:\
I tried compile and it had no errors. I also tried initialize & reset to no avail. I could not post my program because it was too big even when compressed. I have messed with it and found that in my main routine I was calling sub 1, sub 2, ret. In Sub 1 I was calling sub 2, ret. In Sub 2 I was calling sub 1, ret. I removed the calls in sub 1 and sub 2 but left RET. It now works. I am guessing this put it into a continuous loop and then error..? Any insights would be great.
Thanks for the help.

I am having an error that when I add a call subroutine in my main ladder the program does not load on the PLC. It is giving a Status: Idle on the black and white startup screen and stays on the screen. When I take the Call subroutine out. The main ladder and HMI shows on the PLC. Has anyone had a problem like this before?
I have Updated the OS, Loaded a blank program and then downloaded my new program, but its still not working.
Thanks Scott

I believe I fixed one of the problems. I had 2 direct coils with the same address. I changed some code also for the other problem.
I will let you know how I make out.
Thanks, Scott

Hello everyone,
Looking for some help. My program keeps getting hung up when I am storing #40 and #60 into MI 1. Can anybody take a look at this and see what I'm missing?
I could only attach the subroutine as it was too big.
Thank you so much,
Scott

Hello,
I have been struggling on this project for work. It is an automated assembly station. I am still very green when it comes to programming. I went through what I had tonight and tried to make it work. Would anybody be kind enough to look thru my code and give me some pointers? Maybe tell me what I am doing wrong. I haven't had any formal training so I would like advice from some pros.
I have attached the subroutine. Thank you in advance.

Thanks Joe,
I failed to mention that the "Manual" subroutine was for troubleshooting; to make sure I wired my valve stack correctly. That will be eliminated. Thanks for the state machine example. I looked through it and followed a lot of it, but I am just having a hard time thinking of how it would look in an application like mine. It may just be that I am getting use to this type of programming, though. I will definitely be looking into it more.
Like I said this is my second PLC to program (both are unitronics) and I am enjoying it a lot. Do you have any advice on learning programming? Classes or tutorials? I would eventually like to get into Allen Bradley, as that is what is used the most in my neck of the woods, but I don't want to be held to one product as many programmers are. Any advice is much appreciated.
I will give an updated on this project in the next few days.
Thanks again,
Scott

Thank you Joe,
In reference to your list.
#1. Got it. Is this only more efficient or will a regular contact cause potential issues?
#2. This would explain why it was acting erratic when trying the program.
#3. Got it.
#4. I would like the outputs O1 and O3 to stay on or SET during the cycles, but only when holding the anti-tiedown when the reset button has been hit. I added reset coils in rung 8 and 9. Please let me know if I'm out in Left field. Code attached.
#5. Got it.
#6. I read through transitions under help. It is making sense.
Thanks,
Scott

It is in rung 6 and 7, in the same code I put in my first post. Hmi screen is main screen.
-
I have a reset button on the main hmi screen (mb9). When the machine needs to be reset the operator hits the reset button. Then hits the anti-tiedowns which then retracts the cylinders (O3 and O1) and resets mb11 (reset hit) coil.
Thanks,
Scott

Thanks for the reply Joe.
I was testing the reset rung (pic below) and I could not get my coils O3 and O1 to come on until I took out Reset coil MB 11. I was thinking that MB 11 was Resetting before O3 and O1 could energize.. Does that look possible or am I dealing with something else? Do you see anything else that is not "Best Practice" programming in this sketch? I appreciate your help and knowledge.
Thanks again,
Scott

Hi Everyone,
This is my second PLC, it is a Samba. I am having an issue with my set coils. When a set coil is energized or ON, my corresponding RESET for that coil gets energized also. This has me stumped as I believe all my reset coils are isolated until I want them to come on. This is happening to a few coils in the sketch named Machine Logic. Any help would be appreciated. I posted the sketch.
Thank you,
Scott

I was able to communicate to my components. It took a lot of playing. Things that helped me are,:
Hope this helps someone else.
