  1. Hi. This regards ventilation. A room has two air inlet dampers (pretty much like a big air valve in a ventilation duct). Only one is used at a time to regulate temperature in the room, and the other is then closed. When switching the inlet of air from one damper to another; i have not decided what method to use yet. I consider splitting the regulator output in two and let the one damper ramp down to this value, and the other ramp up.  When these values are reached one ramps up to the full regulator output and the other to zero. Not quite sure this is the best solution, and the code is not written yet :) Anyone done anything similar or has suggestions? Cheers!
  2. New to OMRON

    Hi group. I am trying to improve on an existing program however I am not very familiar with OMRON. I am programming an OMRON CP1H using CX Programmer V.9.6 I would like to display an alphanumeric display on a Proface HMI.  I would like the display to show different text based on a user input.   In the screen shots below a user would load a battery into a specific row/column, I will call it a "slot".  The way the program is now the FIFO would load for example the number value 2009, which illogically represents "Row 2, Column 4, which would be slot 9. How can I program a text display to say "Row **, Column **, Slot ** ?  Seeing 2009 in the FIFO stack makes no sense. The images below: 1 - Current Logic that generates the 2009 based on row and column selected.  In this case Row 2, Column 4 would equate to slot 9. 2 - User input screen 3 - FIFO stack based on how the battery was entered.  In this case 2009 would go into the FIFO.  If the operator then loaded Row 1, Column 1, the next number generated would be 1001 (Row 1, column 1.  
  3. Hello:   I need to link  a lot of variables, pointing to CIO address, like "AT" field, but is a large volume of tags to create, so, I have a chance to assign a memory location to a variable in ST like:  my_tag := %100;  (trying to assign tag address to CIO 100) ? If not, there is a method to import tags from a Excel ?   Thanks.    
  4. Hi, I am searching for a  Possibility to Set bits in Set or Reset State. How can i do that? in Example the Code in LD: and in ST EQ_E( Merker79 AND Referenzfahrt_TP_Ein_Aus = TRUE , bDummy , P_Achse_Istpos_pulse , 0 ); PLS( bDummy , Drehrichtung_P_Achse AND M8140 AND Loeschen_Positionszaehler_Achsen AND Startpos_anfahren_nach_Referenzi AND P_Achse_Referenziert = TRUE );

  6. Hi, Many Programms we have are written in Codesys and in ST Language  and now we have a FX5U and I'm trying to Convert some of them. But the both Systems are different, I miss the Librarys like util.lib and FB like RAMP_REAL, BLINK, LIMITERROR which are in Util.lib. Are there Librarys like util.lib for GX Works 3 ? Is it possible to convert Ladder to ST? (I dont have any Idea from Ladder and I'm new in Programming)  Have someone Sample Programms for me for Training?
  7. Howdy, So the program I have has linked up and I've downloaded to the Omron NS-10 just fine... other than when I go to certain screens the text from all the descriptor labels are gone. I can't figure out if its a setting or if its just getting lost in transmission somewhere. Halp. Thanks,
  8. KEEP in ST

    Hi, I have a fairly easy assignment for a school project that has the following components:  -1 impuls start switch  -1 impuls stop switch  -2 El-motors When you push start one motor is suppose to run. Then you push stop and it stops. The next time you start the other should run. Only one motor shoud run at the time.  I solved this using a KEEP function in ladder logic. But I want to be abel to do the same thing in structured text. So my problem is that I cant fint anything to replace the KEEP function. Any help would be much appriciated.  
  9. Send text messages via Omron PLC

    Hello,I'm trying to use the CJ2W-CPU32, westermo MRD 315 to send messages in case of problems to the operators.Where should I configure the text messages, configure the phone number, etc? I need to configure a complete system.Thanks for the support,Regards,Hugo Tavares
  10. 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!
  11. Converting UINT to DINT

    Good afternoon,   I need to convert a UINT (16-bit unsigned integer) to a DINT ( 32-bit signed integer).   Apparently we can't directly assign a UINT variable's value to a DINT's or vice versa. I also couldn't find a way of casting UINT as DINT.   The reason why I need to do it is because I'm receiving data from a socket. The RXLength is a UINT but in order to scroll through  the data array (USINT[1..1])  I need to use a DINT as the array's index, but I can't compare the array index to the array's length because they are incompatible types.   Is there a cast statement similar to:       myDINTvar := (DINT) myUINTvar;   I also tried the following but it didn't work:       myDINTvar :=  (myUINTvar * 1);   Any help will be deeply appreciated.   
  12. I am very knowledgeable with RSLogix5 and RSLogix500, but want to become well-versed with RSLogix5000 advanced algorithms, strategies, and program types—(Ladder, Sequential Function Charts, Function Block Diag, Structured Text), and motion control, such as servo-controllers. . . mostly interested in structured text. I’m also interested in the nuances of RSLogix5000, ControlLogix & CompactLogix regarding design, on-line programming, and off-line programming, etc. Can anyone recommend a course or courses that cover this subject matter? Thanks!
  13. In Part One of the Question: "Can the Omron NJ CPU make the Random Sea?"     There were some fine opinions about that.   This example is what it looks like using Red Lion, Delta Motion RMC75E and LinMot:  https://www.youtube.com/watch?v=SQd6YzBWVvI Recent edit:  The "Big Trycky Omron Question was asked many, many times not shown on this Forum.   I had a very difficult time getting a straight answer from many people at Omron and LinMot.  Probably because they really never tried to do it.  By  the end of THIS thread ( part2 ), Thanks to innoaloe I know that the NJ can generate the position signal, as streaming position data with no time limit, and produce a "randomly" generated model of the ocean's surface.  The "random" part isn't added yet, but, it will work... and the LinMot part isn't added yet .. and it is still unknown if that will work.            
  14. Hi... Trying to keep it simple: Want to make a G5 incremental motor wiggle, CW/CCW in a sine wave motion, Thought this might work:                                                   The variable,  "Angle" is REAL, Phase1 is REAL, AMP1 is LREAL, CSINE is LREAL .. Sysmac doesn't like "Angle" in the FOR statement .. Anyone know why..? Thanks Much, Regards, Michael
  15. Beckhoff PLC Counter

    Hi everyone, I need some help with my PLC programming. I am currently using a twincat 2 software and a Beckhoff CX 8090. Basically, the gist of my program is to send and receive data and datalog the input data received from the sensors and timestamp the received data for every 1 second. I want to create a boot up counter where it will count the number of times my data logging program has restarted(if it did). This boot up counter serves as a health monitoring check to ensure that my program is running perfectly and thus, not restarting randomly when it shouldn't. I am more familiar with structured text so if you have a solution, kindly post it in structured text form. Your help would be greatly appreciated. Best regards, DeadPool
  16. I'm in the process of converting an old Siemens S5 project (with no comments!) to ControlLogix. My first question is in the S5 there is the odd instruction with a '#' in it: - -] [ - - - - (#) - - - - ] [ - - - - -(F00.1) In old logix the # means a file, what does it mean in Siemens speak?   My next question, I have the rockwell document for structured text and also for converting S5 to logx, is there any other resource that would help me understand Siemens structured text?   As I chip away at the project I'll be posting more questions. Thanks in advance for your help.

  18. HERE’S IS A QUICK WAY TO SEND EMAIL (TEXT) MESSAGES FROM THE PLC Sending email messages from the PLC sounds like an easy task. However, very few applications do this on the production floor. This is probable due to the networks involved and using authentication can be complicated. In our example we will use a restricted Gmail SMTP server so no authentication will be required. We will walk through sending email and text messages from the PLC to Google Gmail. Once in your Gmail account, the message can be automatically forwarded to another verified email or SMS text message address. HERE’S IS A QUICK WAY TO SEND EMAIL (TEXT) MESSAGES FROM THE PLCThe PLC used in this case is the Do-More from Automation Direct. The software is Do-More Designer. Here is a blog post that I thought was good to share. Let me know what you think. Garry http://www.accautomation.ca
  19. Hello everyone! First of all, I'm a new comer to this forum from Indonesia. The name's Inno. Looking forward to share knowledge with all of you So I had this trivial, but annoying matter with CX-Supervisor Text Points. I had connected it to NJ101 controller. There I made a sample STRING, let's say "1234". I set this STRING to be stored in D0 memory, which means in ASCII it'll now contains : D0 = #3132 D1 = #3334 Then I use the Display Value (Text) Action to a Text Object in CX-Supervisor. The problem is, each Word on the Point display the LSByte first. So the resulting view in CX-Supervisor is : "2143", while I expect to see "1234" I know this can be easily solved by swapping the bytes inside the NJ program, but I'm curious, does CX-Supervisor has the feature to swap these bytes automatically? I mean, even NS or NB HMI can do so to accomodate Mitsubishi/others String system :D This occured for any Text type I choose (Signed/Unsigned/Raw Binary). Waiting for your suggestions
