  1. Hi my problem may have a simple solution but i cant work it out. I need to use the Divide function but it wont let me use a decimal point in either Source A or Source B. Is there a way to use a decimal point in Logix 500 Math instructions? Im using an AB Micrologix 1400 PLC. Can you only use math instructions with whole numbers? is there a way around this? Thanks James

  3. How to watch the value in decimal directly in the ladder page ?  Default Hexadecimal The only way I can do it is in Watch Tab and I/O map per example Thank you
  4. Hi. I am new to Allen Bradley PLCs and bumped into the following issue, that I cannot find any solution to. When trying to add a module to the I/O configuration I get the attached error, error code 80131940. This prevents me from adding any hardware configurations in Logix Designer. I have tried to reinstall Logix Designer and uninstall all AOPs. I am running V30.00.00 on a Windows 7 Enterprise SP1 OS. Your feedback is very much appreciated.
  5. I am definitely a newbie in the world of PLC's. So I hope this doesn't sound like a dumb question. I do the electrical design for PLC's and have only done this for a few short months. I am currently working with a Point IO PLC. This is the first one I've seen. Because of the qty. of input and output modules, we had to add 1734-FPD and 1734-EPAC to boost the power. Easy enough, I get that. I bring power to the 1734-AENTR.....then, do I hard wire to the next module, or are the next adjoining input/outs connected view the internal power bus? Same question goes for the 1734-FPD and 1734-EPAC. I understand to bring power to those devices, but do I hard wire to the first module or is it automatically connected via internal power bus? I have done my research before I posted on this site. I think some of the installation manuals for these devices are conflicting., I think that's why I'm so confused. Thoughts? Does anyone know of a good trusted manual for such a question. Thanks in advance

  9. Ethernet/ip to modbus rtu

    HOW TO CONNECT AB 1769-L33ER ETHERNET /IP TO MOD BUS RTU
  10. Hi PLC programmers, I got a problem regarding my installation of Logix Designer/Logix5K. Here's the situation... a) Initially installed Studio 5000 without problem. b) I needed to open a program from Logix v20.1, installed RSLogix5k v20.1. After installing v20.1, RSLogix was corrupted and won't open program. c) Reinstalled entire Logix Software. d) Was able to open and convert program from Logix5k v20.1 to Logix Designer v24 but this annoying error occured on v24 (See attached "EN2T")... "Failed to Create Module Profile". All of a sudden, the module (1756-EN2T) I created with working v24 is no longer usable. Now, even when I create a new project, add a module with "Select Module Type", the list of available modules has been trimmed down to what it normally has (see attached "AB_Modtype"). Kept on re-installing entire Logix 3 times, clearing the registry with CCleaner and even deleted installation folder for Rockwell software but the problem is never gone. I even downloaded AOP for EN2T and installed it but to no avail. Now I'm lost and dumbfounded that uninstalling and reinstalling isn't working. By the way the OS I'm using is "Windows 7 Enterprise". I appreciate all the help I could get. Thank you very much. Sincerely, Andrei K.
  11. Point I/O 1734-AENT to LabvIEW

    Hello, I am new in PLCs, I hope you can help me. We are working to communicate point I/O 1734-AENT Series B to PC (LabVIEW) by Ethernet/IP. We need to read inputs from slots and need to write output to slots and the library we are using in LabVIEW needs class, instance and attribute parameter to comunícate with specific slot. I read those parameters you can configure that in the web page allen bradley (you put the IP point I/O in the browser internet) and then configure those parameters in the tab diagnostic messaging but for my case that tab is not visible, so I could not configure this part. Can anybody help for that? and help me to give me more information about class, instance and attribute CIP (Common Industrial Protocol). Best regards Carlos Luevano Test Engineer specialized in Development Software LabVIEW.
  12. Axis Attribute Error

    Hello All, First time working with PLC. Get the hang of it from stuff I researched. Having an issue with an axis setup for a servo motor.  When I try to do an auto tune it gives me an error that axis is not configured.  Source: Config Fault    Condition: MotorDeviceCode- INvalid attribute      ACtion: Immediate Stop Fault Entry: Type 8, code 9 subcode: 1314 stopaction: 4 Statechange: 3   I was wondering what am I doing wrong? Any leads or source information I can use to solve this. 
  13. Hi,  I am writing some routines to decode the data from my Input: data array to User-defined Array Parameters. Is that possible to have a generic routine to decode data coming from more than one module? I have two Module ENode and ENode_1. I have defined User-Defined parameters for the module. Can I make a generic routine to decode the data coming from these two modules and put them in the defined arrays?  the two arrays ENodeData[0] and ENodeData[1] have the Generic User-Defined parameters.
  14. RS Logix Designer Tags

    Hi, Is that possible to define INT data type in EDS file so the Tags for the module in RS Logix Designer would receive INT data type in Input Tags not SINT? As marked in the image, the Logix Designer is receiving data as SINT but I want to have INT data type. Thanks Muhammad Azeem
  15. I have a "paddle wheel" style flow meter that I am trying to wire to my Micrologix 1400. It is a three wire device and there is a tag on it that says it can run at 6-36VDC. So, naturally, I thought to wire this to one of the HSC inputs of the Micrologix directly. I hooked the ( + ) on the meter to 24V, ( - ) on the meter to common, signal to the oscilloscope, and ground on the scope went to common. I see a small 60Hz sine wave @ like 5mv when the wheel is not turning. When the wheel is turning I get a small square wave but in the same mV range. It is not a nice smooth square wave either its all jumbled up with the 60Hz sine wave.  I hooked this thing up to a transmitter and scoped the signal and ( - ) in parallel with the wheel - I get a nice smooth square wave signal when the wheel turns. It is only at 4.5V though. My questions are? Why does't the paddle wheel give me what I am expecting directly? Also, what is the voltage range on the pulse that a micrologix will see? I am assuming that it will not count a wave with a 4.8V amplitude.... Thanks for your help in advanced! neech   
  16. Cimplicity 7,5

    Good Day There is a SCADA Cimplicity and controller Control logix 5561 AB. Communication between them is organized via Ethernet IP. It is necessary to transfer some tags from the Cimplicity to the controller Control Logix. How to do it better? Through Rslinx DDE OPC or write scripts in the Cimplicity? 
  17. 1.Can anyone say how can i communicate control logix plc with ethernet to serial converter. here i am not having any eds file.
  18. Fatek PID gap

    Hello, I need to build a project with PID function. The main objective is to work with pressure (sensor is 0-16bar 4-20mA). If pressure is between 5 and 7bar (7 is set point), I want PID to give scaled values at my analog output. Pressure <= 5bar = 100% Pressure > 5bar and < 7bar = scaled values Pressure >= 7bar = 0% So actually as I understand, I need need a second set point. The HIGH set point is 7. The LOW set point is 5. How am I going to give the low set point?   Thanks in advance!!!
  19. Could someone please generate PDF report for the ACD files on the attached .ZIP file? They are all RSLogix 5000 v20 files, I needed them for a university report which the deadline is today, but I don't have access to a computer with RSLogix 5000 :S Thanks!  ACD_files.zip
  20. Has anybody tried communicating Allen Bradley 5069 Compact logix PLC with Red Lion HMI ?  I am unable to communicate them in spite of adding AB tags via L5K file which gives me no error. I am able to see all the tags in Crimsion 3.0 software in development mode.  However, PLC & HMI are not communicating with each other. I am able to ping to both, using the same program in PLC of which I generated L5K file.  I think it may have something to do with the driver as 5069 is a new line of PLC Rockwell come out with only in 2016.   
  21. To Infinity

    Hello.  This is my first post and I hope someone has a solution. I have a program calculating Gal/sec adding to a running total and have up to the end.  Using REAL I can accumulate up to 16,777,216 (2^24) and using DINT up to 2,147,483,648 (2^31), but I need to have my registers continue past these limits.  I've read through many topics here and have tried the Rockwell Knowledge Base but can't seem to find a solution that truly works.  I have gone so far as to transfer the DINT to a string, cut the string into pieces and reassemble them in an Odometer type concatenation. If anyone has a suggestion, I would appreciate it.  I know I'm not the only one with this problem. PS & BTW - I'm using Studio 5000 v24 with a 1769 L33ER
  22. Thanks for your time.  We have purchased from auction a Getinge Autoclave (sterilizer) with Allen-Bradley controls (CompactLogix L32E).  The machine has a PanelView Plus 1000 installed.  A CD came with the machine w/ the following files.. HMI Project - (.apa file) Runtime (.mer file) Their is also a compact flash card installed in the CompactLogix L32E.  On the Panel View, their is an external Compact Flash slot, but no card, and on the inside of the panel view (if i remove the back cover) their is a compact flash card slot with a card installed.  I haven't checked what is on either of those cards yet.. We cannot get the program to load on the panel view. When the machine is powered on, the panel view goes through a quick dos setup screen and then the screen turns blue and we are stuck with an hour glass icon.  The icon will move depending upon where you touch on the screen.  I can boot the panel view in safe mode (by hitting the default button, then reset) at which point I get a message stating that the machines files may be corrupted and leaves me the options to Download new Firmware, or Continue.  Hitting Continue nothing happens, and choosing Download gives me Ethernet, or Serial options.  The Panel View is connected to the PLC via ethernet so I choose this option and it  gets stuck at this point. We do not want to make any changes to the program, but just to get it to run on the machine.  We do not have ANY of the software. Any advise is greatly appreciated. Craig
  23. RS Logix 5 Compare Tool

    Hi, Could someone explain or direct me to better understand the RS Logix 5 comparison tool? I'm comparing multiple PLC codes and having a little bit of trouble understanding what the concept of "deletion", "insertion" etc are portraying. Since, some rungs are labelled 'deleted' and 'inserted' in the comparison, however,  the rung labelled deleted seems to exist in the actual code?
  24. Hi, I'm a long time lurker and would like to start by saying thanks for all the help over the years, much appreciated!  This is my first post, please be gentle. I'm working through a large project with an L83 (V28) including 75 EIP nodes & 5 servos.  We have a need for quick real-time response of 2 cameras during a quick servo move (taking several pictures).  I've broken my program up into a few event driven tasks (allowing me to chose the execution time interval (5 to 8 ms for more important tasks and 20 ms for less important tasks, etc.)), along with these I have 2 periodic tasks: 1 for my HMIs & faults running every 30ms and 1 for this quick real-time response camera situation running at .5ms which contains my camera and servo logic.  Everything is running well and seems responsive and repeatable enough, but I am now adding the second half of the logic which will essentially double everything (2 up system).  This has made me consider the best structure approach: Is it better to have a few larger routines within a few larger tasks or better to have more smaller tasks containing an abundance of smaller routines or some other different mix? Thanks, JD43
