    I have E-Designer 7.52 Build 344 installed on 3 windows 7 laptops the 2 that the problem is on are Pro 64 and the 1 thats working is Home Premium 64 but I seem to recall having this problem on the the Home one 9 years ago and getting it sorted but cant remember how The problem In Alarms,  Alarms New Alarm Alarm text: When typing cursor stays at left side and can only be moved to the right by the arrow key then jumps to left side after letter is pressed or you can type in reverse Signal:        Typing works normal OK:             Entry is not valid ;May not be blank Copy: Ok: Same result Properties:Ok:Same again Is there anyone who can help me with this as the laptop that works is on its last legs Thanks  
  3. Timers and Structured Text

    Hello group. I am practicing ST programming and am doing this by converting an existing Ladder Logic program into Structured Text. I have created the following attachment and I can see my BOOL objects change state when I touch the respective buttons on my HMI.  The issue I am having is the Accumulating Timer will not start timing when the conditions are met. Can someone with experience in ST advise me what I am missing or doing wrong. Thanks
  4. I'm working on simple structured text program which takes in DWORD values, does some math on them and then outputs in DWORD type. What data type should I be using and how can I make this work?  This is one of the lines from the code(everything DWORD) and I get 'operator not supported by DWORD data type' XPos3 := XPos1 + (2*XIncrement);  
  5. Hi, I have a problem because a TON Timer instance in an ST program does not start running. Is this a known limitation on FX5U CPU's or ST Language in General ? On the internet are some discussions, and there is a person which says it works for FX CPU's: https://stackoverflow.com/questions/58463316/delay-timer-in-structured-text?noredirect=1&lq=1 But not for me.... And some discussions here in the forum: http://forums.mrplc.com/index.php?/topic/20864-plc-failing/ http://forums.mrplc.com/index.php?/topic/37923-calling-a-timer-in-st-code/ The last one is interesting, but it did not helped in this simple case.   For clarification, I created a very small program in GX Works3 (v1.057K) The FB instance in Picture 1 works very well if one sets M10 to True. The ST instance in Picture 2 does not start when setting M20 to True. Has anybody a clue? Any help welcome DWIM  
  6. Hi, Could anyone help me out on how to extract the digits present in a string in sysmac studio... Thanks in advance !!!
  7. Is there any instruction in Sysmac Studio Structure text to detect rising Edge (DIFU/DIFD) ?
  8. Hi, I can’t find an answer to the following and I was advised to ask it here.I’m programming an Omron CJ2M with an MD212 high speed I/O card. I usually do all my programming in Structured text, simply because I like it a lot over ladder or sft.Now, if I want to read the hight speed counter (incremental encoder), I have to make a ladder section and use the PRV instruction to store the present value in a chosen location.The manual says the current PV is stored in A271, but I can’t get a readout there. Apparently the only way to read it is through this instruction.Does anyone know if there is an equivalent to the PRV instruction for Structured text? or another way perhaps? Again, when I check the actual memory adress, there’s no value there withouth the use of the PRV instr.
  9. Q03UDVCPU

    I am new with PLC's and I am learning how to work with GX Works 2. I have two questions, 1st Question: Using a Q series PLC (Q03UDVCPU) Is it possible to convert the language of a project from ladder logic to structured text? 2nd Question: If I read a project from a PLC why is it always ladder logic? Is there any way to read out structured text?
  10. Hallo.  Can someone shed some light on how much memory st takes ? does it use more that traditional ladder? i find that a routine with a couple of thousands of lines uses over 500kB is there any tricks to lower the usage? Or is it just what it is, and buy bigger cpu’s
  11. Hi, I'm new to both structured text and Modicon. I'm having trouble compiling this tiny procedure, meant to scale a number to an integer when the operator changes it. Although I can set the page edit variable to @localparameters.iLTemp_SPt1 with no problems, I can't get this function to compile as either a local or global procedure. What am I doing wrong?  
  12. GX Work2 Comments in Arrays

    I am very new to the Mitsubishi PLC world (I have a lot of experience with A/B and Omron though).  I am having an issue trying to assign comments to an array of Globally scoped bits - I am also using Structured Ladder - NOT simple ladder.  Is it possible to do this?  I have contacted there tech support group and they were of little help.  I don't care if I update the label comment or the device comment, I just want to assign a simple comment that can be displayed (i.e. I am using this for step sequences).   Any help would be greatly appreciated!  
  13. 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!
  14. 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.  
  15. 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.

  19. 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?
  20. 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,
  21. 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.

    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
  24. 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!
  25. 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.
