    Hi guys, I have a PanelView Plus 1000 that I am using to Flash up important alarms from various PLC's. I was wondering if there is a way to set up a Username and password way of acknowledging the alarms. Currently I have a just a button that acknowledges the alarms. The PanelView is in a common area and there have been a number of instances where an alarm has been silienced and the operator for that area was not informed of the alarm. I would be most grateful of any help, Thanks, Conor

    Hi guys, Yesterday in work we has a power "blip". A lot of the plant went down. One of these was a SLC. This SLC has Digital Input and Output card. It also has an Analogue Input card, 1746-NI8. When this piece of plant came back online, none of the Analogues were working. I checked out everything and found the power led was on but the channel led's were blank. I then went online and checked, no Analogues working. So I went off-line and checked the Channel configuration. I found that all the channels were set totally differently than what was originally programmed into them, the enable check box was even unchecked. I changed them all back to the correct settings and downloaded the code. Machine back online everything was ok. Has anyone seen this before or know of any issues that may have caused this to happen. The program was at the correct stage of the process where it had stopped at when the power blipped, so I don't think it was the battery in the processor. Conor

    Hi guys, I was just talking to Zebra tech suport. I have explained what I want to do and sent on info to them, and they are looking into this. He told me that their printers use the langauges EPL and ZPL. Does anyone know if I can send this kind of info out of my L35E or my MVI69-GEC? If I get any solutions or idea's from Zebra I will post them here too. Thanks Conor

    Hi guys, I was wondering if anyone is printing via a CompactLogix. I need to get a printer to print out dockets for me. I need to be able to send the info out from my L35E processor. I will have a managed switch on the other end where the prnter will be installed. On the print out I would like to have a basic template and my PLC sending out the info to fill in the blanks (for want of a better word) on the printed out sheet. Conor I may have the answer already. I have a Prosoft MVI69-GEC. Would I be able to use this to send info out to a printer, and if so would any printer do here?

    Hi Guys, I am using an L35E as a centralized data collection point for my site. I have about 12 PLC's that I need to Read/Write info to. With the exception of two of the PLC's I only have a cuople of tags in most of these. The PLC's that I am Read/Writing to are PLC5's, SLC's and CompactLogix, mainly L35E's. I have structured a messaging counter to trigger each Read or Write in sequence with a timer doing the addition and resettingat a specific number. My timer runs at 100 ms per count. I have each seperate Message at a different count. I was wondering what is the best way of checking how my PLC is performing with all of these messages running, or is it going to be ok as I have the messages running at seperate times (counts). Is there a GSV that I can run to see my system performance. Also, what would the optimal time for the timer be? I.E. is 100 ms too fast or slow? Thanks, Conor

    Hi guys, I am trying to implement an RFID system that will read a tag on a truck. I would need the reader to be about 1.5 to 2 meters away from the tag. I will be able to connect to a managed switch very close by to the reader. I looked up the Bradley stuff, but the tag readers seem to be very small distances, probably better for a production line. Any help would be most grateful Thanks, Conor

    In reply to Cookie Monsters reply: A while back someone told me about Netset man. http://www.netsetman.com. I have used it ever since for setting my IP address on my Engineering Laptop. It is very handy as you can set up to 6 different IP configurations. I think that I have 5 set up. It speeds up the process great.

    Hi guys, I have looked up the documentation and could find a Hart module for the 1734 Point I/O. I was wondering if anyone has done anything like this before. I have some new instruments that I am taking Analogue inputs to my Point I/O. These instruments are Hart enabled and I have been told by the instrument manufacturer that I will be able to take more process values if I was utilizing the Hart on the instrument. He has suggested using a Hart Multiplexer. This Multiplexer would then give me up to 4 Analogue outputs. I was wondering if there is another way of doing this? My Point I/O is connected to my PLC over Ethernet Thanks , Conor

    I have to agree with the guys here. I am able to buy my AB stuff off two different suppliers, and the price differences can be significant. For me it comes down to which one is giving me the best customer support. I will buy most of my stuff off one supplier, but always keep the other in the loop, as this way if I need a part quickly I can get off both. Also the cheaper one does not always have the stock.

    Hi Bob, We have a good bit of ControlNet here on site. I was lookng into re-scheduling before and I came across some good Powerpoint presentations on AB tech support. I downloaded them all from there. I am not sure if you have Tech support contract, but there is a tech note 46577 that shows your exact error. If you dont have tech support I can re-word tech note 46577 ( I think I can do that according to the rules of this site??). Conor

    Hi, If you are online (or offline as well) with RSNetworx, click on the Scanner card, normally Node 0. Then Click on Scanlist. Select the Node that your E3Plus is, the Click on Inputs. You should see where the Inputs are being mapped. You will see the same on Outputs. There is a parameter set around parameter 60 (I think) for inputs, that will let you read current or any other values available. These are set up again by the parameters. So if you Have a look at this link http://literature.rockwellautomation.com/idc/groups/literature/documents/um/193-um002_-en-p.pdf It takes a bit of reading, but is all in this manual. I have setup E3Plus overloads on Logix and PLC5's using this manual Conor]]PS. Sorry, I would go online with Networx to change these parameters.

    Hi again, I have tried out a few of these instructions but I am not getting the outcome that I expect. I have attached a screendump from the code. The data is being read by the PLC, but each Sint has '' around the values. i.e. GEC.Clients[0].ReadData[14] is 'A' My question is how do I read the whole message from the unit in to a format without the '' As far as I can see from the message the end of message comes in on GEC.Clients[0].ReadData[68]. This contains '$7F'. I take it that this is the end of message. I would be very grateful with any help you guys may be able to give me on this Thanks, Conor gec_ascii.bmp

    Hi guys, I am doing a new project were I am connecting an L35E to a Siemens controller. I have the Profibus connected and working, but I have found that there is byte swapping when sending INT data from Siemens to L35E. I have been able to use the SWPB instruction to reverse the byte swap, but this instruction only is for a length of one INT. I have an Array of data coming over, about 100 INT's. Can someone tell me the best way of un-swapping the complete Array Thanks, Conor

    Hi guys, I try and read most posts that come up here as sometime maybe I will come across an issue or maybe I can give someone some help. One thing that comes up now and again is guys talking about their library of AOI's or UDT's. I am only just starting to use these and would like to start my own library. I don't mind having to create the AOI's as I think that it is good experience. In your opinions what do you think that I should be including in my library. Should I just go through some of the code in my plant and start creating as per well used code snippets? Any input would be great, Thanks, Conor
