Hello agian, Trying to write a program for water tank levels, problem is the tanks have over 37000 gallons of water in each but I can only get sums up to 32767 before I get a math overflow fault. Could somone please explain how to get values greater than 32767. ( floats??? double integers???? something else???) and if so how to set it up and make it work. I realize that I can scale it down to smaller #s for the math in the program its self but eventually I will need to be able to set a value of almost 38000 onto the HMI. Need to be able to go higher than 32767 or need a way to work with decimal. ( K 37.725 ) Also tried to install a reset instruction with S:5/0 for math overflow trap and get ERROR " Invalid Data Type?????????? Any thoughts on this one also. Using ML1400. Thanks in advance for you help. Charles

I am a little late to the show (Have not stopped by this site in a while)  this thread is a few days old, so you probably have figured this out by now. But.....That drive has a Copy Cat feature, you will see it in the parameter section kaiser_will mentioned.  You can Upload the parameters from the drive to the HMI.....Then put that HMI into the new drive and Download the parameters into the new drive. It is very easy to do. Also you should remove the HMI first before trying to remove the cover of that drive. (Push the black tab that sicks out of the top of the drive and slide the HMI UP. Forgive me but it sounds like you don't have much experience with VFD's......be very careful they can bite you even after you remove mains power from them. Good luck and be careful. BCS

What is the exact model # of your Panelview and what type of communication are you planning on using between your Micrologix and the Panelview. (Serial-RS232, Ethernet, other?) (Not so sure about the indirect addressing mode for comms between a 1400 and a PV???????????????) Someone can tell you more once you provide the model #.   BCS

Here is a cheat sheet for connecting a Micrologix 1500 and Panelview + 2711P-B10C4B2. These will not match your equipment but it will give you a very good idea of how it is done. (As long as you are not using an old panelview standard, then it will be different) Post your model # and someone will be able to set you on the correct path.   BCS PV_TO MICROLOGIX.pdf

Maybe I am missing something and please tell me if I am but...... the way you have this drawn out wont all the inputs go true when any 1 input is true since you are tying them all together at terminal #2? Seems like if this is 24VDC that you would need diodes to keep from back-feeding every input at the same time. BCS

I have been having the same problem for at least a week now if not longer. Cant paste links to websites, have to type it out. I know this worked before but not sure at what point it stopped working. BCS

Check out the link to this class, and see if he is offering a PLC 5 class anytime soon. http://www.ronbeaufort.com/ Best time and money you can spend, if you are serious about needing to learn your way around a PLC. BCS EDIT: Looks like Oct 5th - Oct 9th is the next PLC5 class scheduled, and only a few available weeks left in the year. Better Hurry!!!

Do you own any Allen Bradley Programing Software already? If you do what software do you own? This may be your deciding factor as to which controller you want to use. The only free version of Allen Bradley Software you could use only supports the MicroLogix 1000 and 1100 controllers. Unfortunately with your I/O count you will not be able to use either of these. So if you don't own the software already then you are looking at having to purchase software also. Now you might want to ask yourself " If I have to purchase software, which version will I use the most in the future". The MicroLogix controller that would fit the description you are looking for would be the 1400 Model. It has Ethernet and is expandable to accommodate your I/O needs. This programs with RSLogix500 software. (Older defined data table type software) (This is also the same software that the SLC you mentioned is programed with) The ControlLogix and CompactLogix type of controllers are the newer generation. They program with RSLogix5000 now known as Studio5000. (Newer Tag based software) Just something to think about when making your decision. If you happen to already have one version or the other, but not both of them, then the decision might be very easy. Regards, BCS

If you are not looking for anything fancy, then why not use the Embedded Web Server in the ML1100 to manipulate the binary data table. That way you don't have to purchase anything else, you already have it all. BCS

Hmmm....well I have personally not tried that, but I don't see why it would not work. I may be dead wrong about that though as I do not find any examples of doing this for a PV only, I do see examples using it to interface 1 controller though. But if its all you got, then light it up and give it a try. From your PC to AIC use a USB - Serial Converter and a 1747-CP3 cable. From the AIC to the PV use a 1761-CBL-PM02 Cable Supply your AIC with 24vdc Try your baud in auto first. Now create a NEW DF1 driver in RSLinx and see if it will Auto Configure. (Don't forget to look at your PC settings to see what Comm port you are using, and set this same comm port in your RSLinx Driver before hitting Auto Configure.) If it works then great, if not you may have to do some more experimenting or wait and see if some who has use this device in this fashion comes along with better advice. Also if you are going to be working with this kind of thing often I would suggest investing in a 1747-UIC, it will save you a lot of hassle in the future. Good luck and let us know if it works. BCS

My friend, The first thing we will need is the correct model # of the Panelview you are using. If it is a 2711-T6C2L1 as Mickey pointed in an above post, then it has no RS232 port, and only has DH485 communication capability. You will need to acquire a converter such as the 1747-UIC to interface between your PC and a Panelview that has only this type of communication. If you would please confirm your model # and someone will be able to better assist you. Regards, BCS

If you have a Sub D comm port sticking out the side of your processor then you have a 1764-LRP. If you do not then you have a 1764-LSP. See Below.

Ok then I owe you a Dollar, I should have stuck with my first hunch. LOL The MINI version only supports Compactlogix and not Controllogix processors. You will need to get a Bigger version of RSLogix5000 to work with this processor. Sorry for the bad news. BCS (I see I said Micro version in my first post, I should have said Mini. My bad)

Yep, I will bet a dollar that's it. The release notes for V21 do not mention the 1756-L61 processor, but they are supported by version 20 and downward through at least V13. (I did not bother to look any further back than this) (Please excuse my shotgun answers, I have not worked with this controller so I have to look for the answer myself) Revision 21.pdf

What version of RSLogix5000 are you using? It would not happen to be the micro version would it? (Just taking a stab in the dark here) Edit: Or possibly using a version of RSLogix5000 that is greater than V20. I just read this in another tread that is down just a bit on this page titled PLC Version Upgrade. Look down and read that one, for more info. BCS

ROTFLMAO If all you need is the IP Address then you were probably right with your first assumption in this case. Just connect to the PV via the Ethernet Port and use something like Angry IP Scanner to get the IP Address? Wait....Here is a good one, I checked the manual for the PV+ and it says that the Ethernet Port on them DOES support Ethernet/IP communication. So...would you not be able to just create a new ETHIP Driver in RSLinx and plug your laptop directly into the Ethernet port of the PV+......I am wondering if the driver would not just automatically populate the IP address of the PV+ just as it would on any logix controller that uses the Ethernet/IP protocol. That would be just too easy. I will pull out one of my spare PV+ tomorrow and try it out but...you would think that would work if you are only wanting to get to the Config Screen to get the IP of the Device and nothing more. BCS

I just happened to be making some changes to a 5/04 myself and had the program open. Here is a screen shot of where you add the card part # and descriptions. This is found under IO CONFIGURATION in the project tree to the left. I am pretty sure you can just push the Read IO Config button if you have the cards in place. You will have to do this in program mode, as I think the processor will fault if the I/O config in your program does not match exactly what is in your rack when you go to run mode. I also think it is recommended to power down the PLC before adding the cards. BCS

In his other tread on another forum, he says they will not supply a PC to run the software on either. Why didn't I think of this when I was running my contracting business. Yes you are hired, but you will drive your own van to the job, supply all the tools and materials you need to do the job, and I will collect the check at the end. If you could pick up your own Workman's Comp policy that would excellent also! LOL When I first read this I had to look at the calendar and see if it was April 1st again.

Tried a couple of more times but it is not letting me cut and paste to this forum. I even cut from one forum and paste to a word doc, then cut from word doc and try to paste here and no luck. Below is a word file with the cut text saved and the 2 zip files. I would recommend you google and read the entire thread like I said above though before trying this. Good luck BCS Edit: Had to zip the word file also, it would not let me attach it otherwise. Hopefully there is something in these files, the way it is going so far I would not bet on it. You can google and get there if not. The file PV_400_to_1500_Reset is the word file. The files that start with PVP are the files I got from the thread. Obviously you will need the 700_1500 for you PV1000 but I gave you both so you have them. Have a good one. PV_400_to_1500_Reset.zip PVP400_600_ResetMEStartup.zip PVP700_1500ResetMEStartup.zip

Hmm...that's odd the link did not work, I copied it right from the thread. I tried to cut and paste directly from one forum to another also and that did not work either. Strange, I do this a lot and it usually works. Try to google this: plcs go to config exe panelview The very first hit that should come up will say "How to go to the terminal config screen on PanelView Plus 60...... Double click on these exact words I list above (not the actual threads listed below it) and it should take you to the thread that will explain how to do this and give you the files to do it with. If not let me know and I will try and get it for you again. BCS

Ok, I got a moment to look for this and found it pretty quick. Like I said I personally have not tried this method but read through this thread and see if anything in here will help you out. http://www.plctalk.net/quanda/showthread.php?t=48497 This comes out of the Archives I think, so you may have to select "View full version" when it comes up so you can see the links to the zip files you need. Good Luck BCS

Don't give up just yet there are still other ways. You are not a big bad intellectual property thief trying to skirt the security password of a PV at British Intelligence or something are you???? Just kidding, give me a bit, I am busy right now but will look for some info for you when I get back, I haven't ever done what I will send you but I did read of another way to get where you are trying to go. Not sure if the fact that the PV is password protected will be a factor in getting there using this method but at this point sounds like you have nothing to loose. Talk again in an hour or so. BCS

On boot up there should be a small white square that will appear in one corner of the PV+ if you push this square it should take you to config screen. I have heard that some versions did not include this white square, so if you are lucky enough to have one of these versions then try: Plug a keyboard into the USB slot on the back of the PV. Then press CTRL, Shift, ALT and the Windoze Key all at the same time. BCS EDIT: Just a thought, you have scrolled through all of the screens on this PV to see if there is a "GO TO CONFIG" button already written into the application, haven't you?

Its a small world, so you never know, you might make it this way one day. BCS

Porteno Suenos, Do what you have to do to make it all work out in your head for the moment, but I assure you that once you get your head wrapped around using RSLogix5000 Tag Data Base you will never want to see another B3, N7, T4, etc. Not that there is anything wrong with those but once you get the hang of using Tags that you are in control of naming instead of being tied down to a predetermined set of data files it is very liberating. I mean think about it, you put B3:0/0 in your Logix500 program and what is the next thing you do.......you put a instruction description on top of it and call it something that you can relate too like "Fan_Forward. (so you know what the heck B3:0/0 is) With Logix5000 you just forget about having to go and select the B3:0/0.....you can skip that step and just make a bit and name it "Fan_Forward" or anything you want that makes since to you. It has been a while since I looked at the tutorial I sent you, this is what I used to help me write my first program in Logix5000 but I think it tries to get you to make it look like the old data file in 500 also. I don't do that, I make my tag names something that makes since to the project I am working on, to someone who might come behind me and need to understand what is going on with just a glance, and most of all something that makes since to me. After all if you look at an instruction and it says B3:0/0.....?????....you say what the hell does that do. But if you look at a instruction and it says "Fan_Forward" and you are working on an application that has a fan, well....you get the picture. It gets a bit more involved than this for sure and I still have much to learn myself, just getting started good with Logix5000. But after playing around trying to teach myself for some time, I did the best thing I have done since I put a ring on my wife's finger. I went to a class here in the USA for 5 days (and not just any class, I went to PLC BOOTCAMP). (Google it and check it out) Let me tell you it opened my eyes right up and now I see clearer than ever and it has built my confidence greatly. If you have the means I would highly recommend you do the same, it will put you light years ahead of the game in only 5 days. Take care and program on, BCS (Also just so you are aware....not every programmer "Maps" their I/O so you will not always see this in all programs. A lot of times the "Local"X:X.Data.X" will simply have an "Alias" but we will leave that for another thread)
