  1. Hello Everyone I have a problem to connect FX5U with Inverter Mitsubishi D700. ( no  respond from inverter) . I did read and following the manual. Could any one can help me?
  2. Hello, Back in December 2017, we replaced a customer's PLC-5 control system with a CompactLogix.  Everything was working fine until about a month ago, when they started having an I/O fault, Code 16 - I/O module connection failed on required module.  At first it was showing up on multiple modules, and also the end cap.  However, after a few more faults, it was only showing up on module 2.  We replaced that module and the faults stopped for about a week and then returned.  The module we replaced is a 1769-IA16. Any idea what may be causing this?  The customer insists nothing was done to the panel since the initial installation.  
  3. I am using NB Designer for last one year without problems. But from last week i am getting new error Background PLC control recorder 0 error! while compiling and not able to update the HMI. Please help.
  4. Hello, I am quite a newbie in PLC programming. I am trying to add a PID control function into a ladder program of FX3U PLC that was made by the person before me who used GX developer. I have read the manual, but still not sure if I understand it correctly or not. Please help me with questions below: 1. For parameters [S3]+1, how do I set the bit value? My understanding is that I need to align the bits I want, and then convert to Decimal number to set it, is this correct? i.e. If I need bit to be 0100001, do I set the parameter to 33? 2. How do I know if I am doing backward or forward operation? I think what I am doing is feedback control loop, does this mean it is a backward operation? 3. If I set auto tuning bit (parameter [S3]+1 bit#4) to 1, will this make the the program to run auto tune everytime I start the PID? 4. For parameter [S3]+22, [S3]+23 and [S3]+24, the manual said it will be occupied. Does this mean it will be preset by the program which I shouldn't mess with them? But how do I set the output upper and lower limit in [S3]+22 and [S3]+23? Also, I couldn't find any example of PID parameter setting in the manual. Not sure if I missed any important section in the manual. So please point out to me if there is any example. I also attached the manual on the PID page just for a quick reference. Thank you in advance for the help. FX3U Programming PID.pdf
  5. Hi guys, I am trying to connect AB compactlogix 1769-L30ER through Ethernet cable to my laptop. I use Rslinx version 3.9 When I enter IP address it can find the CPU without any problem but it does not show the I/O. When I check the driver diagnostic, it says: Can't set port type to 288: no harmony object for this Ethernet I should mention that my OS is windows 7 and I turned off firewall as well. So, what does it mean and how I can get rid of this message? Thanks
  6. Good morning all, does anyone have any experience communicating to an OMNI Flow Computer through a MNET card, Im getting data back but it is not what i expected.  Should I be using Enron/Daniels? Byte Swapping? Thanks
  7. Hi,  I'm new to TwinCAT 2 and i'm upgrading a long time design (hence the TwinCAT 2 reference), to read a more sensitive torque signal.  I'm using a Beckhoff CX1030 as my PLC Controller.  I needed to add 'homing' to my motor sequence and confirmed with Maxon, im using the function blocks correctly and in the correct sequence to establish my 'absolute zero'/'home' position.  The motor has an output to write to:  ControlWord, which tells the motor that the position it is sitting in is '0.'  My program compiles, it runs, it writes each function block, but it's not seeming to get back to the test run opMode, even though i tell it to and the function block performs the 'Write' function.  it's stuck at zero and not reading an analog input signal from my torque sensor.  so im getting an artificial torque reading through every test.   i think this is related to my tare motion.  I start the program, home the motor, get into profile velocity mode, tare my sensor, enter profile position mode, go back to position 0, then back to profile velocity mode, run a test, sample data, go back to 'home' or '0.'  I wonder 1st, is my variable not linked properly through the system manager?  2nd, i set a boolean variable to set the 4th bit to 1 in my control word write (setting the 4th bit high will set my current position to absolute zero), but did i not connect the program to the main sequence properly?  looking to read a valid signal again and see that my motor moves back to 'home' each time.  Do i not need to home the motor after the tare, since the tare nulls out the torque value after the tare? after this i need to program my sample period, instead of it being fixed, as it is currently written and then use my home position as my trigger to start sampling.... Beckhoff applications department is overloaded, currently and can't help and this is all beyond the knowledge of the general support line.  I've gotten fairly far, on my own, but of course, the project is under a time crunch.   Does anyone know twincat well enough to help guide me?
  8. Hi Guys! I have a problem with Motion axis move (MAM) command. There is an Allen bradley servo motor what is working well. But I need to add a new program section, wich is in  a specified moment, the axis should move a certain distance. I think I need to use the mam command, just I dont know how can I configure the motion control part. I need to make a new tag ? or what ? I need to use a user define ? PLS help me.   
  9. HOW TO CONNECT AB 1769-L33ER ETHERNET /IP TO MOD BUS RTU
  10. We have an auto-clave unit purchased at auction roughly 4 years ago.   CompactLogix L32e and PanelView Plus 1000.  All has been working for us until last week.  Suddenly, the program seems to freeze up after around 30 seconds.  I can still touch the panelview and the touches are registered, (the mouse icon moves) but the program does not respond and I can tell the program is frozen because the clock which displays seconds stops counting. When i boot into safe mode (clicking white box on boot) the system does not seem to freeze at all.  I am able to navigate those menus w/o issue.  We don't have any of the software to connect to the PLC.  I understand this is a somewhat broad issue, but does anyone have any idease where i can start in troubleshooting this? or is their any further info i can provide which would be helpful?
  11. Anyone have any suggestions on the best way to pass a little bit of data between a SLC 5/03 controller and a compactlogix? The current problem I'm working through is the SLC 5/03 does not support Ethernet (only RS232 and DH485). So now I'm trying to find a solution.   Thanks,
  12. 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.
  13. I am fairly new on this forum & PLC's, usually i read and get tips from here.I use a RsLogix 5000 PLC software. I am currently working on a project at home that requires me to read from a Access DB. What type of Instruction or method do i go about, initially reading from Access? I know Excel is possible It's an existing system. Add on functionality/feature. I am using a barcode scanner that will link up to a Access DB to verify the barcode is legit and send this info to a different system via PLC/EthernetThe access DB is used because its a older system, it uses that. So it is possible? and guessing from what your stating, its is more involved to get the system working eventually?PLC = A&B 1769-L23-QB1 CompactLogix Controller I am using FactoryTalk View Studio as HMI, do not have SCADA.I have a control logix chassis. Thank you in advance...

  14. WeinTek to AB PLC Issues

    YoungNDumb posted a topic in HMI & SCADA

    I am connecting a WeinTek eMT3105P to a CompactLogix L2 series PLC via the WeinTek Rockwell PLC (CompactLogix) - Free Tags driver and I cannot for the life of me get the thing to connect. I have all my tags imported and have played around with all the settings in the manuals I can find. Any help/advice would be greatly appreciated. I know my IP addresses are correct and if I connect my cable directly from the HMI to the PLC I still get the "PLC no response" message 

  15. CAM Control Data

    Omarrn posted a topic in Mitsubishi

    Hi everyone, I'm trying to use the cam control data by using an MR-J4-A-RJ and MR Configurator 2. When I switch the input "CAMC" to ON, I see that the output "CAMS" is switched to ON which means that the cam mode is activated. When I switch CI0 to ON to choose the Cam Data No.1 and switch ST1 to ON...nothing is happening like if there is no Cam Data. Please, have you any issue or idea ?? Thank you in advance Omar
  16. 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.
  17. 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
  18. Hello, I was hoping for some help in trying to read/write to a handful of bits in a CJ1M-CPU13 controller from a Compact GuardLogix. The CJ1M rack has a CJ1W-ETN21 card that is already communicating to a handful of Yaskawa drives. Is it possible for me to communicate with this controller from a CLX unit over ethernet? I don't believe an ETN21 card uses EIP but is there a way around this? Right now, I'm struggling to even find the IP address of the ETN21 card as the CX-Programmer file provided to me by the customer does not have the card in the IO configuration and I've never worked with Omron PLCs before. I found a CJ2M to CLX guide but it assumes communication over Ethernet IP and the ethernet port is native to the controller. Any help at all would be appreciated. Thanks!
  19. Hello everyone! Im hoping someone could shed some light on a issue im having. Im having issues with a 1794 ow8 output module. This module is used to control 8 hydraulic cylinders that push biomass into a burner. The overall problem is that roughly once every couple months a output will short in the on state and force a coil on, activating the vavle full time and burning out the coil. Each seperate output is fused on the module with a 2a fuse and each modules incoming power is also fused at 2a. The output that is shorted did not blow its fuse. The 'ON' light is not activated but 120v still runs through it. Since each valve has 2 coils and one is forced 'on' the main fuse will blow once the second half of the valve is activated because the valve is fighting itself. It is not just this one module, this happens on other modules that serve the same funtion as well. This is a contractor installed system but they have been no help so im left trying to figure it out. Could my seperate inputs be fused too high at 2a for this type of card. These are parker valves 120v 60hz with a max 1500psi pushing wet hog/chips. Any suggestions would be really appreciated!
  20. 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   

  21. Cimplicity 7,5

    KAZ posted a topic in GE

    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? 
  22. 1.Can anyone say how can i communicate control logix plc with ethernet to serial converter. here i am not having any eds file.
  23. Hi everybody: I'm writing here because I have an Etherhet problem with my compactlogix 1769-L32E. I connect a crossover cable between my pC and the controller, then I run the BOOTDHCP server program . The BOOT DHCP window only shows the MAC of the PC, the controller´s MAC doesn't show even if i wait for more than 10 minutes I hope you can´t hel  
  24. Does anyone here use this? Control Draw If so how useful do find it? Worth spending the time on learning or better off with another product? If so what? My application is going to be for in-house management and design of control systems for a food manufacturing plant.   Thanks.
  25. Hello, I am currently working on programming my first sortation system.  Attached is a blue print of the in feed conveyors and their loadout lines.  As boxes merge together they will be scanned by the barcode scanner.  From there we will be told which lane each box must go down, from the WCS.   My question is, without encoders, what would be the best way to control this system? Counting the packages as they pass through the photoeye? Or setting timers?   Thanks, James Sorting Conveyor Layout.pdf
