  1. Hi all. My experience is using Studio5000 / RSLogix5000 to program CompactLogix PLC's. I need to use a basic (cheap) PLC to get data from a Control Techniques Drive (about 9 DINT's for Speed, Torque, etc) and then display on a PanelView Plus 600. Its a bit extravagant to use even a basic CompactLogix for this, so I believe the most basic AB solution I can go for is the Micro820.In Studio5000, to add in CT Drive comms, I simply just add a Generic Ethernet Module and setup the IP address of the CT Drive and the Connection Parameters and that is pretty much it. I look in the Controller Tags and there is my DINT array that I can interrogate for the information. Very simple.Anybody any clue how to replicate this in Connected Components Workbench for the Micro820? I cant seem to fathom it out at all?Just to clarify, I am not doing any control of the Drive from the HMI or Micro820, merely displaying on the HMI parameters like speed, Torque, etc.Thanks.
  2. Trouble Wiring a Simple LED with a Micro820 Controller

    Hi everyone, Recently, I started working with the Micro820 Controller Embedded I/O. My project is simple : when the output _IO_EM_DO_00 is set to true, an LED light turns on. But, even though it's super simple, I can't make it work. Here's my setup. If you need more information, feel free to ask anything !
  3. Hello,  I am working on a project to connect a PLC (Micro820 by Allen Bradley) to a simple RS-232 alphanumeric OLED display. I am not too familiar with structured text language, but I have worked with micro-controllers that use similar high-level languages (mostly C-based).  My question is: is it possible to use connected components workbench to program my Micro820 to output ASCII commands to an off-the-shelf RS-232 alphanumeric display? Are there libraries that make life easier to do this?  I welcome any recommendations to related reference material or command tutorials, thanks!
  4. Can't connect to Micro820 controller via CCW

    Hi everybody, Recently, I started working on a project. I want to develop a program for a Micro820 controller (2080-LC20-20AWB) using CCW (Connected Components Workbench). I built a little motor circuit for testing purpose. However, after building the program and downloading it to the controller, I tried to connect to my controller via CCW, but I can't. When I click the button "Connect", CWW crashes OR a window saying : "The controller has unnacepted changes" appears and asks me if I want to "Download current project to the controller" (wich I already did) or "Upload the project in the controller to overwrite current project content" (wich is grayed out). When I choose to "Download current project to the controller", CCW starts downloading the resource, but fails. In the "Output" window, there's a line saying : "Download failed for Device:Micro820: An error occured while reading from GETACTIVERESOURCELIST.". The problem is that there's no documentation at all concerning this error. I even tried to reinstall CCW, but it didn't fix the problem. I joined some images so you guys can see what I'm talking about. Don't mind asking for more details !
  5. Printing through a Micro820

    Good morning,   I want to connect my Micro820 to a load cell, read its value and then send it to a printer so I can have a generate a label with the product's weight.   I'm open about the printer model but I really don't know where to start and couldn't find any good articles about  it. Does anybody know where I could find some more information about the subject or even program examples? Thank you  
  6. Hi at all! A little brief to understand my situation... I'm creating a new project with an analog input (4-20mA) to determine the level of a tank. The instrument send me a value that correspond 4mA => 0% and 20mA => 100%. With the AI_Conditioner UDFB from RA i can correctly rescale the mA value to a %.  Then I need to "estimate" the volume of that tank, so with radius and lenght i can calculate it (no problem so far). But after that, the value is too much variable (the 4-20mA is not very stable)... So to resolve I can accept to rounding to the nearest 20... But, how can I do? There is already an UDFB made for it? Thank you at all!
  7. I am currently trying to message from  a micro820 to a SLC 5/03 (via 1761-NET-ENI ser. D).  In the 800 messaging manual ( , there is a CIP generic message example that gathers the CatalogID of the device at a particular I address.   My micro is My 1761-NET-ENI is I can get online with both, and I see both processors in Linx.  However, when I execute the example code in the micro, the CatalogID is not the SLC, but the 1761-NET-ENI. All I need to do is write an ASCII string to the SLC 5/03.   NOTE*** Ultimately, I will not need to speak DIRECTLY from the 820 to the SLC--instead the Micro820 will send a CIP message (...a barcode string) to a server that will then send a bunch of data to the SLC 5/03.  So:   BARCODEà[ASCII]àMicro820à[Ethernet]àServer(gets a bunch of data)à[Ethernet]à1761-NET-ENIà[DF1]àSLC5/04(oldPLC)  
  8. Hi Guys, Hoping someone can help me out.  I have a time variable, which stores the elapsed time of a timer.  I want to convert this to HH:MI:SS format so I can display on a LCD panel.  Couldn't find an easy way to do this. Thanks in advance, Ben.
