Did you loose power to something? Is their any type of screen lit up at all when you say colors are you talking colors of graphs or buttons?

What would you like to do Read and Write stuff to the DCS? I just started with a new company that has alot of DeltaV and I have seen a serial card in the DeltaV chasis to talk to a SLC com port. What a difference from AB PLC's to DeltaV.

I am thinking about implementing an HMI, but don't know which way to go and thought maybe you guys would shed some light on what you use. I have a couple of SLC 5/05's running on ethernet and want to display some graphics and stuff in a control room. I didn't really want to go with a panelview, but something on a PC and the only thing I can think of is RSView with RSLinx, but wanted maybe something different. Got any suggestions?

If you are going to use this router alot and have not bought it yet I would recommend one for a little more money. I also use this router for doing some programming and I have to have the panel door open for the router to get any type of signal and it kicks me off every once in awhile and the signal stregth changes all the time and I am only about 30 ft. away from the darn thing. Just my .02.

I say this on Ebay today and thought it was quite interesting. Has anyone ever tried it out? I emailed the person and they said you can use DLL in VB or EXCEL. Don't know what DLL is yet, but I might be finding out. Ebay

From what I understand is the 3150 is an older model, don't know if you can even purchase it anymore. I am sure you could use a serial port to do the same thing, but for the hassle its easier to use the Prosoft card I just put 4 of them in and wasn't bad at all.

I have taken a 5/03 with a basic module and used that to communicate to Danfoss' 2800 series drives, they to use the FC protocol, the reason I used a basic module is my channel 0 was tied up to a pc. It's totally different then a modbus protocol. From what I understand its Danfoss' protocol nothing standard about it. If you call Danfoss' and ask them for their VLT 5000 series serial communication doc. it has everything in their about their FC protocol. Or if I can find my file I can email it to you. Good luck it took me about 2 weeks to finally get everything going I had like 84 drives on my network and couple of inverters in between to handle that many nodes.

Does anybody know if you can use an expression for a indirect address'. For example ADD(Test[whocares-1],1,test2);

That would explain why I couldn't find the darn thing in the tag database. The new things that you learn about these Logix controllers. Thanks again.

Can you use BCC its alittle bit easier to compute?

I noticed that also. I have two of those cards into a rack in slot 5 and 6 and I have the same processor. I noticed it only happens to me when I go and try to put it and run mode. I clear the major fault and try it again sometimes it may take two or three times to get it to go. The other thing that I noticed is that my online communications with my laptop really slows down with the setup that I have. Having that many copies is really tying up my scan rates. I am hooked up with 100mps and man is it slow. I would hate to be using another type of processor with a different network. Hope to see if someone can answer your topic!

Anyone know how to take a DINT and convert it to a binary value? I am trying to take a Dint and convert it to binary and then put it into excel so I can see each bit that is on.

For number 2 I thought I could do that, but when I goto RSLinx and find the address to copy and paste the link it does not go down to bit level. I only get the whole word. Whats up with that?

I have always had bad luck with thermocouples being linear. When I redid our boilers I switched them over to RTD's and never looked back. When you do your PID loops make sure you scale your input from 3277 to 16384 and 0 to 16383 and when you setup your PID set your Smin and Smax to your engineering units, then of course you have to scale your control variable coming back out. Hope that helps!

I am new to this control logix stuff so bare with me. I am trying to use a BSL instruction to test some outputs, but my problem is that this instruction HAS to use a double integer. So what I used to do in the old SLC and PLC would be set a bit in a integer and use a timer to keep shifting it left, and just use a MOV instruction to move the integer to the output word. It was easy to move a 16 bit integer word to a 16 bit output word. But now with this 32 bit stuff it gets a little more complicated. I started off using the MOV instruction to the output word then after the 16 bit I had to put in a xic to ote 16 more times to get the higher part of the word. Anybody got any good suggestions?

Thanks TW that is what I was looking for. Instead of a MOV using a BTD. Thanks again guys!

Let me try this out. How do you do a screen capture? help.ACD

I know you have to put a DINT in the BSL or when you compile it it will error out. But every time the timer gets done the BSL rung goes true which would shift the bit over one. So the next rung has the MOV which moves the entire BSL destination word right to the Local output word which is only a INT. So after bit 15 in the BSL dest. word is bit 16 but the local output word only goes to 15. Its a 16 bit output card. Make anymore sense or did I do even worse?

Let me know how you make out because that is my next project. We just purchase 210 Yaskawa drives and I am going to run those with I think the Prosoft modbus module and have never done that before. From what I have been told is the module does alot of the leg work for you, which when I did the last project with the Danfoss FC protocol I had to it all. Good Luck

Hey Phil, I did a project last year that involved a SLC 5/04 and 180 Danfoss VLT 2800 series drives. I don't know about the 6000 series but I know that the 5000 and 2800 series don't use Modbus they use Danfoss's protocol. And I took a basic module to send and receive the strings to each drive, had to use a basic module because channel 0 was used for a pc. Hope this helps you out. B.J.

I agree with swimmy, I have been burned to many times by letting people tell me that they have all the backups and that they are the most recent. Bottom line go online and get a recent copy before you do anything.

I agree with the above, using a high speed counter. If you try to do it in the program you may miss a couple of counts due to scans, where as the module does not care about the scans and still keeps track of the counts and it will do everything you said you need to do.

Very good explanation. You then break down even farther. For example if you had a digital input card in slot 2 of your rack and in the program you see I:2/0, which means in the Input image file, word 2, bit 0. Same goes for the outputs. If you had a digital output card in slot 3 of your rack then O:3/0 would mean Output image file, word 3, bit 0. Most of the other files, except the B file you USUALLY use the whole word, but it all depends on the programmer.

But make sure you try to get one with a full blown com port. My previous on did not and it became a real pain somethings would work with a usb to db9 converter and some would not.

How about using a BSL/BSR and if the part is bad put a one in the array and use your timer to shift it.
