  1. Hi Everyone,I have a customer that needs a CQM1H (CPU51) replaced. They purchased the processor new-old-stock from a source they found online. It arrived in the original packaging and had the safety label around the top of the unit, so it seems that it is as advertised and no need to suspect that it would have problems. I purchased secondhand, a power supply to attach to it and program it from the bench instead of in the machine. The customer also provided me with an SD card containing the project file(s) for the machine. I am able to load the project in CX-ONE (running on Win 7) just fine. My computer has a native serial port (COM1) and I built a programming cable to work with the DB9 peripheral port according to a diagram I found online.The processor powers up right away with the ERR/ALM continuously on. No other LEDs came on initially, and after a bit of playing around with communications settings, I finally landed the right protocol and my computer seemed to identify the processor correctly. I compiled the source and attempted a transfer to the PLC. I got some failed message (or maybe messages) at the end of the transfer. It did seem to send all of the binary code, it just ended with an error message that I unfortunately didn't write down or grab a screenshot.Anyway, what I have now is a PLC processor with the ERR/ALM LED on always, I've never seen it in RUN mode, and now after the programming attempt, I'm seeing the COMM LED strobing at about a .5sec frequency (with or without a cable attached to the peripheral port), AND I cannot get CX-Programmer to again acknowledge the processor anymore. I'd like to reset this back to the way it arrived to me, but can't figure out how to make that happen offline. The DIP switches don't seem to cause that effect. I should say also that the DIP switch settings are all OFF except 3 and 7.Any help is much appreciated!Thanks,John  
  2. GT Designer - Alarm Screen

    Hello all.. I have a program for my customer.  There is an alarm page.  They want a solution screen for alarms. For example ; if there is an alarm , they will click a button near the alarm. They will see solutions for that alarms in a pop-up page. Is it possible with GT Designer  3 ? Thanks
  3. Alarm History on GT1275

    I'm using a GT1275 HMI with GTDesigner3 and am trying to add some Alarm Logging capabilities. I've made an alarm page and have it working correctly, but the problem is once the display is full it stops showing current alarms. Is there a way to have it only show the 20 most recent alarms? Make it where the newest alarm deletes the oldest alarm? Or at least make it where I can scroll down to see the latest alarm?   I've attached some screenshots of the current alarm page and settings. I tried the "clear oldest history..." button but I can't set a specified target value. That may not be the right way either so IDK.  Thanks. 
  4. Hi, Is there a way to write an Event Name to a string variable in Sysmac Studio? I'm using a NJ-301. My problem is that I can detect that there is an error and get the Error Code using functions GetECError, GetMCError, GetPLCError, etc, but I want to get the Event Name associated with the code (in a string variable), to display that string on an HMI (not from Omron). Is this possible?
  5. FX1N

    I have a problem with PLC not seeing the input. I am using a FX3S, however, because I still am using GX Developer, it will only recognise it as a FX1N. My problem is I did a small programme for an alarm on a "Blow Down" system for filter cleaning on Silos. Tested it at home with a cyclic timer, everything working fine. Got the controller this afternoon and found I had a problem. It looks like it's not seeing the input to reset the time out timer. Worked for a while, then fell over. Using X0. The switching time I am monitoring is 20msec, which I thought would not be a problem. This is going to be a major setback for me with this project. Eight of these controllers. Any help would be great.
  6. i just got my NX1p2-1140DT controller with a R88D-KN04-ECT. i conneted every thing and directy got the 87 message on the display. i found out dat is becous wrong wiring I dont have the I/o cable incallt with omron they where saying that i don't need it and i can controll the motor controller full via ethercat. i already try to change to pdo mapping. what am i doing wrong? can someone help me? is it indeed true i dont need the i/o cable  thanks in advance for helping.
  7. Good morning Today I have the honor to present you our project, on which we have worked the last months. We have been annoyed for years that when creating software in special machine building, sometimes the same/similar messages are created over and over again and then they are described similarly or the same in the machine documentation. The thought, if the mechanical components are mostly the same/similar, the error description can also be "copied" (at least initially). An Excel table with the error numbers seemed to us here a good beginning, however it would be practical, if with each message text also still the description to the message in a document, including pictures, tables etc., were deposited. This was then the point where we first thought about an online tool. This also solves problems with collaboration and makes it possible to work together. Also additional languages can be added if a machine is to be rolled out to a new market. PLC-Alarm is a young Austrian startup founded by PLC programmers to ease the handling with machine messages and their descriptions. Therefore we tried to solve the following problems besides the creation of an error list: Working together on message lists Hierarchical creation of message lists Inheritance of message texts and message descriptions to lower-level projects Adding additional message lists to make message texts more variable. Adding a description to any message text in any language via Google Docs. (Connection to Microsoft Word-online is in progress) Document template for uniform presentation Combining all message descriptions into one machine document file. Highlighting used messages to avoid having unused message text in the message list. And to shorten the machine document file. Upload a file containing the used message numbers to mark them automatically. Any export options for PLC, SCADA and HMI systems possible. (Currently optimized for TIA Portal only). Suggestions for additional features welcome As mentioned in the last point, currently only exporting for a TIA Portal text list is possible since the first customers are also programming on Siemens. But we are looking forward to extend this according to customer requirements. Do not hesitate contact us via e-mail. We invite you to test our free web applications and leave your feedback. The application is already successfully in use at the first customer and we are looking forward to more users.

  8. serial input string

    Hi  I'm quite new to plc but very new to mitsubishi.   I have an input string eg G+002.7 which represents a weight. I wish to take in the input string then move/convert to int omitting first char,   On other plc's i have been able to use a modifier like d200[2] then the no of chars. How do i achieve this in gx works3   Any feedback gratefully recieved   Paul  
  9. Hi,I want to read transducer signal on PLC.I am using 7kg60008ab/nn transducer and it's analog (4-20mA) output is connected with analog meter.Can I connect the transducer current output (4-20mA) signal to PLC analog input in series with analog meter display???So that I can read the value on PLC simultaneously with analog meter?
  10. Output polarity selection

    Hello to everyone. Nice to meet you all. How are you? I hope you are doing well. I’m developing a program with the purpose of make something similar to a pulse train in the output. However, sometimes I need the output to be a “positive” pulse and sometimes a “negative” one. By positive and negative I mean the polarity in relation to the pulse train source. I’m trying to use a pair of bits in order to switch between the two choices of polarities. I attach a simplified version of the ladder diagram I’ve made. When I thought about the logic, it seemed logical to me, however, it isn’t working as supposed. SM0.4 is a pulse train source. According to the software manual, it is a pulse train with 50% duty cycle and a cycle time of 2 s. That it to say it says at TRUE for one second and return to FALSE for another second. I assign the value of that variable bit to the M0.0 memory bit. I get the negative version of the pulse train logically negating it in the Network #2.                 I assign the value of two inputs, I0.0 and I0.1, to other two memory bits, M0.1 and M0.2. ·         When both inputs are in a FALSE state, the output stays FALSE, disregarding the state of SM0.4. (Case #1) ·         When I0.0 is TRUE, M0.1 is TRUE. However, Q0.0 stays at FALSE no matter SM0.4 is TRUE or FALSE. I attach a pair of pictures. (Case #2) ·         On the other side, when I0.1 is TRUE, M0.2 is TRUE. In this case, the output shows the correct behavior. It is the negated version of the pulse train source. (Case #3)                 Has any of you experienced something similar? Is there a better way to execute my purpose?                 I’m not executing the program, just simulating it with KincoBuilder from Kinco. However, it has always worked fine for me. Thanks for you attention. I look forward for your responses. Kind regards!

  12. unit of time in D8284

    Hello PLCmaniaccccssss, What is the unit of time in 'average time for the channel -1' (D8284) while programming for analog inputs? I have moved k10 to D8284 in my program in gxworks 2, does that mean the time average will be taken for 1Sec or 10msec or any other time unit??? I require this to eliminate the flickering of the input from the load cell transmitter. Thanks and God bless!!!
  13. Hello all,  I have a temperature sensor with a reading range of 10F to 212 . The input card I am using is an Allen Bradley 1734 IE8C 8 Channel Analog current input. The current input values are 4-20 mA. Currently I have my raw low at 4000 and raw high at 20000. Can anyone explain how do we go about selection of this values ? I found these values in the configuration tag of the input card properties.  Thank You

  16. I currently have a Rosemount 87 series flow meter connected to a 1756-IF8H analog input module.. We are not receiving flow from the device, and the channel is showing a diagnostic code of 009... I can not find a diagnostic code list anywhere explaining what this means, has anyone had any experience with the diagnostic codes for HART Devices?
  17. Q68ADG - Abnormal Analog Input

    Hi guys, So I found that CH2 on Q68ADG is abnormal. Whenever I short the termination, the digital value goes max to 4096. Input is set to 4-20mA with normal resolution. I tried to simulate 4mA-20mA but still same result. Does this mean the CH2 is damaged? Equipment at site is normal and give 5mA signal. Thanks!
  18. Hi, guys.I am struggling to develop a solution for a costumer in a Historical Alarm Viewer screen, I am new to Cimplicity and to database supervisory interface. Among other things, the customer is asking to:- Change the "A"; "R"; "G"; "N" notations under "log_action" column to somenthing more intuitive for the users (operation). Please have a look at the image "image.jpg";-Change the point manager process "MASTER_PTMR0_RP" log under "logged_by" column to the user that is currently logged in. Specificaly saying, when I send a command (changing a setpoint or issue a reset command, for example), although it is the user acting, the historical alarm viewer logs the action as "MASTER_PTMR_RP". I Imagine that is because this process is reponsable for exchange point data to/from the IHM points database, but it is still essential to the system administrator to know which user sent that reset command or changed the variable setpoint.The log inputs at the image "image.jpg" has boolean and integer commands (".CXX" sufix);-Log into the historical alarm viewer if the user logs out and what user logged in.It is valid to mention that I am using the ALARM_LOG table (apparently it is the only table working with the application, DATA_LOG, EM_LOG and the others simply do not work, they don't show any column at all, honestly I don't know why).I tried to use Microsoft SQL Server Management Studio to edit the table information, but, somehow, it seems to be blocked to edition.I imagine they are some specific configurations, but I have no idea on how to acomplish them. Maybe if I could use other tables would fulfill the requirements, but , like I said, they are not working (right now I am trying to re-configure the Database Logger from the beggingin to see if it works with other tables).If you could give me some inisights on how to change these settings I would be very grateful. I will be happy to give more information if needed.Thanks in advance.
  19. Has anyone found a way to put the UserAlarmViewer messages into a Label? I use 3 different alarm levels and would like to have a single line alarm banner. In NJ, I use an Array of Bool for triggers. In Siemens, I made a message banner that cycles through each message every 3 seconds from a text file and displays the string in a label. Logic is much different in Omron so rewriting is not possible, nor does Omron use VBA.
  20. Hi all, I am using alarms to generate reports through sql . But sometimes my alarms are getting missed and due to that my reports are not getting proper expected output. My alarm bit is almost high for 3 to 6 seconds , however i have observed that its getting missed . I dont know why . In below image after @22.41.03 the next snap should have been captured around @22.41.33 Instead of that it captured @22.42.03 have anyone faced issue with alarm missing issue? Any suggestions would be very helpful.   Thank you.
  21. MITSUBISHI A2SH-S1 CPU

    Hey i want to know that in mitsubishi A2SH-S1 CPU how can i determine that battery voltage is what and if battery voltage is low then i want to on an output so that i can change the battery with the new one so that my program does not gets erased. 
  22. This is a 1756-IF8 rev 1.5 Analog Input module. This has happened a couple times where the Module Input Data, (not mapped), goes to the high limit and freezes (Data Monitor data is static).  Plant operators pointed out the trending wasn't accurate. There is no fault on the module, no yellow triangle on the system tree for the module.  The Module properties show no faults, and RUNNING. I have done a "Reset Module" both times, (Module Properties - Module Info tab), while monitoring the module data.  As soon as it resets, instantly the Data Monitor starts showing live data. I'm going to try and replace the module at first, but I have some concerns. Has anyone run into this before? I can't seem to find any information on the "Reset Module" animation, and what it actually does.  Any information, (or where to look), would be appreciated. I don't like to hot swap, but I believe I will need to in this case, (utility).  Will the current properties, e.g. scaling transfer to the new module? Thanks Dave Redman

  24. Hello Sirs! I have a problem with PF527. I get alarms 'control sync alarm' and 'module sync alarm' occasionally. I suppose this meaning that PLC is missing some data from the PF527 device. How to confirm this or what should I do with the problem? Any ideas? Motion group update period is 8ms. Also this device is the last device in the ethernet line. I am thinking to pull the cable directly to the switch near PLC. I am not sure does it help?
