  1. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close. I never made a pls program I start researching few days ago and seams to be very complicate to make it. I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica
  2. Hi! I have my 1756 IF8 wired in high speed differential mode but i can't configure the RTS smaller than 11 ms. What I understand it should be possible to set as low as 5 ms if module filter setting is 1000 Hz. Is there anything else that i have to do?
  3. Mitsubishi Analog

    Good day everyone, I know am quite new in this forum, but... Please has anyone here actually worked with the analog module FX2N-4AD of Mitsubishi?  I have one here with me that I intend to use in controlling a process that will be requiring 4-20mA. Unfortunately, unlike S7-300 or SLC 500, that is quite straight forward, this has been messing with my head since morning. And oh, by the way, am using Version 8 of GX-developer.   Any idea on how to go about navigating this mysterious island will be verily appreciated.   Thanks. Francis

  5. Hi, I am a beginner to PLC. I am currently working on a home project with Allen Bradley 1100 model. The project is to build a door open-shut cycle tester.  The motor I have purchased is a Bodine Brushless DC34B/FV INTEGRAmotor. My goal is to utilize the Allen Bradley to to control the motor and then the motor drive a shaft to open/shut the door. Through the LCD screen the of PLC, we can set and view the amount of cycles.  I have finished the initial stage of wiring. But not sure how should I start on the programming part. Could any of you give me any hints on the programming portion? Thank you so much. 
  6. I'm using TM221CE40T PLC with TM3DI16 DI extension. I'm programming it using SoMachine Basic. In the program I implemented a counter (%C0). I've read in the documentation that %Ci.V stores the current count value. I want that to display this value on a Magelis HMIS5T. How could I store the current count value (%Ci.V)? Thanks in advance!
  7. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,
  8.  hello there ! all the variables are reals ... can anyone explain why i get a different result when i calculate c2 first ??? the two programs shown in the pictures are exactly the same ... the only difference is the posistion of c1 and c2 . please help me . It's not a logic  attitude in programming ..... Any ideas? Thank you
  9. FX3G-2AD-BD Store Peak Value

    Good day, I'm new to this forum and to mitsubishi PLC but was hoping for some assistance with a programming issue. I have been through the hardware and programming manuals without luck for this issue. Hardware: FX3G-60mt FX3G-2AD-BE Settings: Structured ladder/FBD Current input mode on: M8260 (first board, first input)   What I need to do is to record the peak value over a cylinder stroke period. The hardware manual explains how to average the value using averaging time, however I basically need to peak hold and send that to a D register for go no-go compare.    Process as follows: Contact closed, monitor D8260, contact open, move peak value from D8260 during monitor duration to D205.    Thanks in advance for any assistance. -Swervomotor

  12. Having problems with the analog drifting. Over time the counts change. I have checked grounding and have tied the analog common to the DC common which helped clean up the noise. I am using a Balluff analog linear sensor 0 - 10vdc for the iputs. Both channels seems to drift. Any Thoughts?

  16. Current Monitoring

    Greetings, I've been having some issues with a vacuum pump breaker tripping... I think I've figured out the problem and resolved it but I noticed that several of the other motors have current monitoring on the HMI but the person who set this up is no longer with us.  I'm wondering what I need besides an analog input for my control logix processor (which I have) to setup this project.  I'm not sure if the other motors are just monitoring one leg of the 3 phases or if they are somehow showing total current?  any ideas and recommendations would be greatly appreciated.   thanks,
  17. First post. We recently upgraded our machine from an SLC to compactlogix. In the SLC 5/05 we used analog 1746-ni8 cards for pressure and position sensors. When we moved over to the compactlogix 1769 l36erm with 1769-if16c cards we seen issues where the analog values had very little definition accuracy. This can be resolved by changing the filters but then the response time of the card is to slow and we miss data. All of the relevant code from these sensors are in their own task and ive tried periodic, event and continous tasks but none of this helps. The strange thing is with the SLC we never seen these issues. Any ideas how i can improve the reponse time when the filters are set low?
  18. Have a PLC5 project with remote racks with digital and analog I/O. For test purposes have wired AO to AI and have set up the BTW and BTRs. Problem is I put a value in the N11 register for the particular AO (N11:66 - BTW) and it doesn't appear in the other N11 register for the particular AI it is wired to (N11:4 - BTR). The AI - N11:4 continues to read a value of "8259" in decimal/"2042" in BCD, despite any value I put in the AO N11 register. The range of the AO is 4-20 mA with a Raw min of -4095 and a Raw max of 4095 and the range of the corresponding AI is 1-5VDC/4-20 mA. If I remove the wiring arm of the AI, the N11 register will read "4135" decimal. Would appreciate any fdbk as need to get working as system for customer will not be migrated to newer RA or Siemens system til next year. Cant get support out of AB for questions as only have standard "tech connect" tech support contract and PLC5 requires you to have "Legacy automation" tech support added to your "tech connect" stnd contract.
  19. PLC Programmer Job

    Hi there! I`m a PLC programmer from Romania and i work in automotive industry. I know to program in Step 7 and in Codesys. I`ve been working with S7-300 from Siemens and Wago 750-881. I am also designing the electrical drawing for my project in a software called WSCAD. I am trying to leave abroad because i have a low salary here and i am wasting my knowledge. Can anyone give me an advice or help me with finding a normal paying job in plc programming? Thank you very much in advance and have a really nice day!
  20. Hello! I have a PLC S7-1200 (1212C DC/DC/DC) and a few question about programming S7-1200 in TIA Portal v13. 1. I want to make "upload station", because I am not surre whichone project is the last. But, when I start upload data, the error hapens, and the decription of error is: The name of the station "S7-1200 Station_1" is already in use in the project. How and where can I change it? 2. And the last question: I try to connect my S7-1200 and Weintek simualtion. There is all time :"PLC not connected". I have chceck everything: PLC is OK, communication PC-PLC ok (ping ok), windows firewall off, administrator rights ok, configuration made with manuals, (CPU - Siemens S7-1200, IP: 192.168.1.100, port 102, tags import - ok.) I have read the manual many times, and check settings - nothing change. Maybe have someone problems like this, and found a solution?

  21. Greetings, I'm ok with RSLOGX 500 but am an absolute beginer with RSLOGIX 5000 and was wondering if anyone had any simple sample code just to study. I would love something using analog input and or analog output. thanks in advance.
  22. I am converting a PLC-5-40 processor that also has a SST side car for Profibus Dp communication to BK3100 modules on the equipment. To a Control Logix L-72 processsor using a Molex SST-PB3-CLX card to the Profibus modules. Everything went some what smooth until I got to the SSI transducers in the Profibus. The word arrangement is not coming in the same as with the PLC-5. Is there anybody else that has run into this problem and is there a solution. I have contacted Molex, Balluff and Beckhoff the first 2 got back to me I am still waiting on Beckhoff.
  23. I'll set the scene a little before I explain the issue that I am having. I have an application where I have a Linear Servo Slide acting as a Press Kick-off cylinder on a ceramic press. In order to trigger this Slide accurately, I have installed an Absolute Rotary Encoder (a Turck product) to the press, which outputs an Analog signal for its specific position. I then have this as an input into my CompactLogix L33ERM through a 1769-IF4 Analog Input card. Within my code, I'm trying to capture the moment where the press has presented the part out of the die and it can be ejected from the press cavity without damage the part. Mis-timing on this ejection and the part will clip the die pad tooling and incur damage upon ejection. Now, one last point of clarification, I am a Mechanical Engineer by trade, so I don't claim to be an expert programmer. But I have learned a lot and have gained experience in programming applications like this, so I can learn quick and should be able to program this task. I have had my local Allen Bradley guy look at the code I'm using for this application, and he thinks it looks good, but I'm still having issues. What I have done, is within the code, I have a window that I look for, of the encoder's position, to trigger the ejection shoe to fire its sequence and kick the part off. However, I have had to make this window so large in order for the code to see it every press cycle, that occasionally, the ejection shoe will be fired at the back end of the window, which is actually too late, and my part is being damaged. Attached is a snapshot of the code. The OkSamplePress.DN is actually a timer that I have that looks at the current press rate and puts a delay in to not allow the kick-off to fire too early, because I was actually getting a glitch before where the kick-off would fire prematurely for some reason. I don't know if anyone can offer assistance on this or not, but I would greatly appreciate any help at all. Its become quite frustrating, as the rest of my machine functions quite well, and this seems to be the nagging issue I can't get rid of. Thanks in advance...Josh
  24. I've got a PLC stack with a Q64AD analog-digital converter card. I am attempting to read the digital output value of channel 1 but I am having issues. First of all here is my simple PLC program: I got the program from the Q64AD user manual. You can see there is a blue '0' on the right of line 0. I assume this is the value that is being read? When I monitor the D11 device in GX Developer it shows a '0'. The following is a screen from Online > Monitor > Buffer memory batch. My card has a base address of 0x60 and channel 1's offset is 11d (0Bh). The value on the highlighted line does change so I know that the analog card is correctly picking up on current changes from my source. Lastly here is an image of my digital inputs. I have set up the Q64AD card through the GX Developer PLC Parameter window and left all settings as default. I initially used 'K11' instead of 'H0B'. I have also tried using the MOV command (MOV U0\G61 D11) but that game me the same result. Can anyone spot the flaw in my program of configuration? Do I need to configure the PLC in order to use the 'D' devices? Should I try copying the value somewhere other than D11? Thanks
