  1. No i got what you are tyring to say, I am trying to do that at the moment. Ill work on it some more and if i have no joy ill post an example of what im trying to do. Thanks, Sal
  2. Hi, What im trying to do is put a timer on delay between a memory flag coming on and output to a memory word. Can this is been done in twido soft and if so how so?? Regards, sal Oh i forgot to mention also that i have several lines in this rung and i did try and fit a timer in there. regards, Sal
  3. Ah ive done it, using memory bits. Thanks, Sal Sorry I didnt seen your attachment until just now, ive done mine a little bit different but it works anyways, thanks, Sal
  4. Yeah im not 2 sure why im using what im am using, its the only logical thing i could think of when doing it. Reason why i sed different memory words and different values for each word is when i configure the MES/SCADA software buttons i assign those buttons to send a value to %mw on the PLC (sorry if i seem like im telling you what you already know, im just explaining what im doing) Im not to sure how to write bits, if you could show me that would be great or even point me in the correct direction so that i can learn it. Regards, Sal
  5. Hi, Dont worry about it, ill figure it out somehow. Regards, Sal
  6. High, Ive done another programme it seems like im getting closer but got a couple of issues with this new one. The green light which is output 4 does not go off when an issue button is pressed. When a second issue button is pressed and has not been acknowledged but the 1st issue is raised acknowledeged and resolved the green light comes on. I know in the programme that is what it is meant to do but i dont want to do that is there any solution to it. I have attached the latest programme and symbol table, sorry again for the zip but it is the only way i can show u what i have done. Regards, Sal andon4.zip
  7. Hi, Thanks for taking the time to look at my issue. Sorry that i have not explained myself clearly. What i have is a traffic light stack. One RED, one YELLOW one GREEN and one BLUE. What im am trying to achieve is when the operator presses a safety issue button the green light goes off and the red light starts to flash, when the problem is acknowledged the red light than goes solid indicating a problem is being looked at. If in theory another button is pressed doesnt matter which one but say the teamleader request button is pressed the yellow light thats starts to flash (red light is still solid), the teamleader than acknowledges is the yellow light goes solid and than resolves it now at this stage there should be no green light because the red light is still on, but the yellow light should go off. What im trying to acheive is the green light should only come when there are no other lights on in other words when all the problems have been resolved. The reason why there are so many outputs to the ONE green light is because i was just experementing. Im very new to PLC programming and ran out of options any help would be appreciated. Regards, Sal
  8. Hi again, This kinda follows from my other posts. What im trying to do is create an andon system which is activated through buttons on an MES/SCADA screens on a PC. I have configured the buttons to send certain values to memory words on the PLC which is working great. I am now stuck at the programming the PLC. I have got to a certain point but i cannnot figure out the other part of it which, is again due to my lack of experience and knowledge. What i have done so far is when a button is pressed on the Pc for example Safety Issue the red light blinks on the traffic light stack, when another button is pressed for acknowledgement the red light goes solid and stays solid until the resolved button is pressed and the green light comes to say everything is ok. This goes the same for Quality and Assitance required which are both Yellow and out of materials which is blue. If i press either of the Call/issue buttons the lights will blink simultaneously and go solid when i press the acknowledgement button respectifully. What i want to do is when for example the assitance required button is pressed and the safety issue button is pressed and when the assistance required is acknowledged and cleared i do no want the green light to come on because the safety issue is still occuring. This can be for all combinations of the issues. I only want the green light to come on when a problem or a combination of problems has been resolved. I have tried several times adjusting programme but it sill wont work I have attached a zip file because i could not attach the .twd file it wouldnt allow me, there is also a csv file. Regards, Sal andon.zip
  9. Yeash sure thing. The OFS server was in the wrong PLC mode. i have options of UNITY, PL7, CONCEPT, X-TEl, and ORPHEE. For this particular type i had to select in CONCEPT. So i could see everything hit the datalogger and the OFS data quality was good but was not getting through to the PLC. Regards, Sal
  10. i got it i was making a silly mistake, thanks for all your help. Regards, Sal
  11. Hi, I tried that, but it is not working, i can see the value hit the data logger and have checked the OFS client to see if that MW is good but still cannot get it to put a value in the PLC. Regards, Sal
  12. Hi, What i am trying to achieve is to out to a plc so that a light comes. I am trying to achieive this via some MES/SCADA software, when i send a value through the software it should switch on the light. I am doing this through OPC server and a data logger. When i send the Value through it does go through the OPC server and i can see that value in the data logger i just dont know of any commands to use in Twidosoft to say when that value comes into a memoryword or memoryflag or an input or any other command in twido, the output should be to switch the light on. any help would be much appreciated Regards, Sal
  13. Thankyou works perfect. Regards, Sal
  14. Hi, Could some please tell me how to make an led light flash, instead of just coming on solid. What i want to do is when a switched is press the light flashes. Later on my program will involve when the switch is pressed again it will come on solid and when it is pressed again it will go off, but thats way later. I am new to Ladder/plc programming and this may seem like a simple problem to you more experienced guys so i apologize for being unkowledegble. i have telemecanique plc and i am using twidosoft v3.5.
