  1. Control Logix 5561

    Hello  We have just purchased some equipment with a Control Logix 5561 (1756-L61/B Rev 13.40). The compact flash card is missing from the unit but the seller says the unit was running in his facility prior to shipping. Does the 5561 have internal memory where a program is stored? Is the Compact Flash used only for recipes and persistent data? Thank you
  2. I'm wanting to get upload the program from a CompactLogix L31 Controller.  I'm using a generic (non Allen Bradley) "C2G brand" usb -->rs232 cable coming directly off of my laptop because I don't have a serial port out.  The rs232 side of the C2G cable is a "pin out" or male end, and as you can see in the picture, the serial port at Channel 1 on the controller is also male.  I'm using a generic (non-Allen Bradley) null modem (female-->female) cable to complete the connection.  Ultimately, I'm not seeing the controller on linx.  But that's a result of me not being able to configure the driver.  When I try to auto configure this driver, Linx gives me an error saying, "Unable to verify settings due to a NAK!" btw, the rs232 cable going into channel 0 is for the HMI on the machine. A pv600 1. How do I get online and upload the program from the controller? 2. What does NAK mean?

  4. logix 5000 array

    Hi Guys! I have a problem with array filling. I use rslogix 5000 software. I have to save the timestamp sometimes. I can save it with GET instruciton. Its a dint array which have 7 elements (year, month, day....and so on),  But my problem is I dont know, how can I solve that, they are in a bigger array. So like an array within the array. Idk it is possible ? I hope you know how I mean.  So I have 7 dint value in one array, and I want 1000 array for this. How can increase the position of the array number ?  Can anybody help me with that ?  Thank you in advance.

    How could I find ON State duration of an Input/Output, in Compact Logix PLC? So it would help me to show in HMI that how long the I/O is ON.Kindly assist me.Thanks in advance
  6. Insert existing attachment A lot of automation cells we get done are made outside of shop so we don't typically have any current acd files for the plc. I am trying to make changes to the program but uploading seems to be giving me some problems. The initial upload seems to work fine I can select a file to save to and I begin to see the file being upload, the problem comes after about two minutes near the end of the upload. Attached is the error I see after the upload stops. Has anyone seen this problem before and know of a solution? Any help would be appreciated. Current controller Studio 5000 Logix Designer 28.03.00 1756-L71S
  7. 1734 IA4 confusion

    Hello All, I will first state that I am very new to the world of PLC's. I do the control drawings where I work. I'm trying to figure out the 1734 Point IO, specifically the 1734-IA4. The manual states "Module power is supplied from the internal power bus". Does this mean I do not need to run ANY power wires to the modules? The installation manual shows points 4,5,6 and 7 as "L1" wires?? The system I am designing, from left to right has the following: 1794-PS13, 1734-AENT, 1734-FPD, Followed by Qty. 11 1734-IA4's. I'm bringing 120VAC and 24VDC to the 1794-PS13. From the 120VAC terminals, I run wires to the FPD. From the 24VDC terminals, I run wires to the 1734-AENT. On the first 1734-IA4, I would think I should bring any power there, because its already back plane fed...….correct? Or DO I run power wires there? Thanks in advance
  8. Device point error between Parameter and PLC

    Hello all, I am a beginner with PLCs programming. I have an issue on GX Developer programming software from Melsoft trying to program my Mitsubishi Q-series PLC. CPU is Q03UDCPU. When the program is written and I try to upload it to the PLC, with the write to PLC window, I check -Program -- MAIN and -Prameter -- PLC/Network/Remote, click EXECUTE and a message appears : "Device point that is set in parameter is not match the device point in PLC". I can't fix it. In Parameter - PLC Parameter - Q parameter setting (window) - I/O assignment tab : I have (see image). Whe I use CHECK button it says there is no error. The X41 input device is plugged on slot 1/00. I am making this folowing the instructions a PDF I found on the Mitsubishi electric's wesite : Q-series basic course (for GX Developer). Thanks for the help, A. S.
  9. MAOC Instruction Help

    I'm using a 1732e-ob8m8sr scheduled output block and the MAOC instruction to create a punching task. I'm already somewhat familiar with the instruction but I'm not sure if you're able to have two different MAOC instruction scheduling to the same armorblock. The first five outputs I want to make an output cam using position and duration as the condition for a punching task, but the last three outputs are cutter blades that need to be enabled at specific start and end position. I would also like to be able to phase shift (compensate) these features separately. Can I use two MAOC instructions as long as they don't try to overwrite the same output?
  10. 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

  12. 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
  13. 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.
  14. 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

  18. Ethernet/ip to modbus rtu

    HOW TO CONNECT AB 1769-L33ER ETHERNET /IP TO MOD BUS RTU
  19. 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.
  20. 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.
  21. 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. 
  22. 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.
  23. 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
  24. 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   
  25. 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?
