  1. Home automation

    NikosGR posted a topic in General Topics - The Lounge

     Hi all     Just a few words about me. I am Nikolas or Nik. I am electrical engineer mostly in industry. My knowledge in automation is enough to excecute my duties as maintenace engineer. I can reed ladder and also i am able of microcontrollers programming only in c. During my 35 years of working in that sector i made some automation projects at work medium size but never were involving HDMI!! The truth is i like these things a lot and i am not afraid to try new things and get knolidge even at that age. Now lets go to my question.    I am building a house and i want to use automated systems.The general idea in the first stage, is to use master plc in the house with an HMI wall mounted in the entrance and connection in a private hub for using also an ipad as remote control in the house. This master will have 2 slaves. One for handling all the outside area and automated doors as the heating system from the garage building with a local HMI, the other will controll the swimming pool.   So get them all together can you advice a PLC that can have communication with wifi,other microcontroller boards(arduino or pic) and other PLC's with affordable price.
  2. If anyone can help me with this, I want the machine only get into run state whenever there is an User logged in. If no user logged In and trying to operate something I will prompt an String message 'Need to login first'. and If logged in/logged out status i want to monitor on PLC. Though IN panel view it doesn't allows to operate  anything if not logged in but I want to monitor the status on PLC.
  3. Hello Everyone guys, Did anybody has used the 1734-PLM Starin Guage Input card from Helm Instruments for Contrologix PLC? HELM instrumenst gave a set of instructions for calibration of the loadcell at first but it doesn't works, HELM instruments is helping me on this but just in case if anybody knows anything about it. I have checked the wiring and it is correct. WhatsApp Chat - Ken helm.zip
  4. Hello everyone, now we are using Kinetix 6000 Multi-axis Servo Drives and TPM 025S – 031V – 6PB1 – 094C – W5 servo motor from Wittenstein, the main function of the servo motor is to elevate the welding module up and down. Several months ago, the servo suddenly increased the torque by 50% compared to normal state, which caused UPS several times in a shift. we went down to the machine and found out the locating pin was worn out and misaligned with the main transport plate. We replaced it and the torque went back to normal due to the welding module was aligned with the main transport plate. The E64 fault started to appear after this problem and still on till now. We did something that we thought can solve the problem: - Upgrade the PLC Logix L73 to L83 but it's not compatible with system so we keep using L73 - Replace the servo drive to the new one - Replace all the cables, check the connection if it was right or not - Check grounding, it was normal - Check the physical components connected to the servo, everything was ok - Measure vibration of servo motor & magnetic field - Replace the servo motor with the new one - Check looking assembly and alignment - Invite Rockwell and Servo expert to the site All the things we do but E64 keep showing so we bypass the E64 by changed feedback noise to status only and the system continue to work. Has anyone experience this before and can you share what you do to solve this. We want to eliminate the E64 completely so the feedback is true and we can we know the true root cause when it send signals, thank you everyone.
  5. Dear Team,   We are looking for a suggestion to drive a motor which is away about 2100 Meter from its starter. The Pump is located in a pond in the forest which is 2000 Meters away from the nearest building. The pump capacity is 55kW and we are considering 55kW HD VFD as a starter. As we see the distance is much higher we are looking for you valuable suggestion about how this thing is gonna work without any abnormalities.
  6. Good morning I have a problem with communication with a Yaskawa inverter, specifically GA500. The device communicates via the EtherCat network. Communication works, but when I want to change my PDO, I have a problem as shown in the screenshot in attachment. The problem occurs when I add the "Operation Command" variable. I have no idea what the problem is. I did not find a library on the Omron website that could support this inverter. thank you in advance for your help.  
  7. Hey there, we want to upgrade some of our old TSX87 PLCs to new Schneider M580. My boss gave me an order to make a plan. My basic idea is to only use a M580 processor and some communication cards. For the I/O we want to use some Beckhoff bus couplers. So we got the possibility to convert our old Grafcet to new ones via software by Schneider. But if **** hits the fan we only have to change the processor and can use another system like Siemens or Beckhoff without changing the I/O devices. My problem now is, that i don't know what bus i should use. I can't find many informations about the supported busses that the M580 is using or i can't find informations if a specific bus is working with it. I would prefer the Ethercat bus by Beckhoff. Can somebody say if it is working with the M580 processors or do i need to use some special communication card for it? Maybe someone used it already in this combination.   Sorry for the bad english. Greetings from Germany
  8. Hello! I am using PLC TM221CE16R and SoMachine Basic v1.6. My PLC has firmware 1.6.0.1. I use analog expansion bus, input module TM3AI8. Everything was working fine for 2 hours until suddenly I got next message in SoMachine Basic: I/O expansion configured but is absent or inoperative. I/O expansion bus is not started. Since then ERR LED is always blinking. I already tried deleting program, updating firmware, removing expansion module in configuration page, removing/adding physical module, selected module as Optional, removing battery - nothing helped. If I try removing application, ERR LED is still blinking. Seems like I can't delete previous program, something like config file is burned into PLC.  On the other hand: if I write some simple program, PLC works fine. It turns on/off relays correctly. Just expansion bus is not working. It is not working even if it's not configured or attached physically to PLC.Can anybody please help me? It is really frustrating.
  9. Hey everyone, I'm new to programming PLCs and I've run into a problem. I have a Micrologix 1400 Series B PLC, and for the past month, I've been using a free trial of RSLogix 500 Starter. But now, the trial ran out, and so I bought a license for "RSLogix Micro Starter". The problem is that when I downloaded my updated file to the PLC for the first time with micro starter, the PLC's outputs don't work anymore. I checked the PLC screen and the inputs from the HMI screen are getting recognized, but the inputs from the physical sensors are not. Also, none of the outputs are being activated on the PLC at all, which I can tell by looking at the I/O status on the PLC screen itself. I then uploaded a new test program, where you press a button and a light turns on, but that doesn't work either. I haven't changed any of the physical wiring, only thing I've changed is that I'm using RSLogix Micro Starter as opposed to RSLogix 500 Starter. I spoke to a Rockwell technician about this and he said that there shouldn't be any problem, as I haven't done anything wrong. So I now ask everyone on this forum if they could help me out a bit.
  10. I have this hardware configuration of an extension rack for a M580 PLC projet using EcoStruxure Control Expert I export the.XHW file by following the procedure below: https://www.se.com/uk/en/faqs/FAQ000256454/ And I am trying to rename the DD1602 card using the file, however, when I rename the card as a show in the next image (selected in green), and re-change the file to the .XHW extension, when I re-import it into Control Expert, I get an error saying: unknown fatal exception, even though the only change I've made is to the name of the card. I know I can rename IODDTs instances manually in Control Expert, but in fact I'm trying to automate the process of renaming IODDTs because I have a lot of IODDTs to rename, which is why I thought of using the XHW file. Does anyone have an idea of what I could do? Thanks in advance

  11. Omron plc to Citect Scada communication

    adi1612t1 posted a topic in Omron

    Hi Guys, I need some suggestion & solution regarding my recent project. The CQM1H plc which was used earlier is burnt and I am replacing it with CJ2M series Omron plc. Program transfer is possible from CQM1H to CJ2M. But the main issue is the system is controlled by Citect SCADA version 5.50 pack C. The communication of plc and Scada is through 2wire twisted pair cable. I just wanted to know when I replace the plc and convert the program do I have to change any settings or parameters in Scada? If I keep the same previous plc parameter in new plc and check the tags correctly in new plc as per old plc then the new system will communicate with Scada? I am new to citect scada so please provide your support and help.
  12. I am working on project where we integrate Omron Microscan Barcode reader to Schneider M218 PLC to read Barcode text. In Microscan we enabled TCP/IP and Port number. From scanner Data coming properly. But coming to PLC I am using Read_var function to Read Data from scanner. I am not getting Scanned text in PLC. Is there any alternative function to read TCP/IP with Port Number Data to read using PLC?
  13. Hi gentlemen, I have I bottle capping machine and I'm reading the torque value from one of the Sureservo2 drives. As the bottles pass through the machine, I need to display the peak torque value and hold it until the next bottle passes through. This machine could run up to 100 bottles a minute. I would also like to display a 10 bottle peak torque average. Does anyone know of a good way to do this? Any help would be appreciated.  
  14. Hello I am looking for how to convert a plc program TSX 47  It looks like the program was with PL7-3  I would like to read this with my pl7 JUNIOR software is it possible ? I have the TSX 4070 CONSOLE
  15. Hello im using  EcoStruxure Machine Expert  1.2 and i missing IEC Objects  tab  on the Controller properties. thanks for answers!    
  16.  We have been tasked with saving money on equipment within our 4 plants here in the USA. I would like to investigate using low cost HMI's, I've had great success using C-more in the past. Has anyone had any of the several low cost HMI's attached to Emerson PAC (AKA GE Prophecy) PLC's? has there been any connectivity issues? I'd like to try one to replace the Emerson HMI's which are hard to source, and expensive. I believe any time setting up a low cost option would offset the cost of the Emerson, and open up our choices of HMI's and not be boxed in to one brand. We also use Profinet along with Ethernet connection, I believe the Emerson HMI only uses Ethernet (for us) but if there is a Profinet version that is easy to set up, that would make it an easy sale for me.   This HMI would also have to work with the older 90-30 series PLC's, but i'm pretty sure the communications have not changed much from the to the stand alone RSTi-EP and RX3i PLC's. Any advice would be appreciated.  Have a great week. 
  17. Hi there,  I'm downscaling my business in Western Canada and have some legit software licenses I'm going to sell. This was my first thought as to where I might explore selling/transferring licenses, but I'm also open to polite suggestions.  I have: one Studio 5000 Full Edition ESD Software (9324-RLD600ENE) (software & valid license) two Siemens TIA portal software packages & licenses with Step7 v14sp1 and WinCC Comfort Advanced V14sp1 (software & USB dongles) an unused Simatic WinCC SmartServer license (software & USB dongle) one Progea Movicon 11 Scada/HMI developer license (software & USB dongle) one Progea Movicon NExT DEV3-FL (developer license) (software & USB dongle) an unused Progea Movicon NExT Scada license (RTCS3-F-1K+WB3-1K) for site install (software & USB *unused) one package of Schneider Movicon with license (Vijeo Designer, Unity Pro S, and SoMachine) (software & USB keys) Thanks!

  18. Hello all,   I am working on a batch computer for a concrete mixer, and the computer that was running the plant before has stopped functioning. It was an old PC running MS DOS. The code is encrypted and replacing it is not a cost effective option.   I therefore am looking into using a PLC to control this batch plant. I have a setup that was in progress by another employee who no longer works for us, it is a CLICK PLC from Automation Direct, and it is supposed to be paired with a EA9 T8CL touch screen HMI from the same company. I would like some advice on just some basics, I would greatly appreciate some input.   I essentially only have one input, and that is an analog scale, 0-20mA input. I have digital outputs for sand, gravel, cement powder, and a water meter for adding water to the mixture. I have one final output, an additive for reducing the required water in the concrete.   What I would like to create is a program that when it is told to start, looks at the scale, and if the scale is less than say 100 pounds, opens sand until it hits 1700 pounds (as an example), then turns it off. Then it turns on the gravel and adds that for another 1700 (again for example, all these are variable), turning the gravel off after. Next the cement, and so on. I don’t need someone to write the program for me, but can someone point me in the right direction on using an analog input to turn digital outputs on and off? Again, your help would be greatly appreciated.   Thanks for taking the time to read this long post.
  19. Hello, everyone! I am following this YouTube tutorial where it teaches you how to add a block of Modbus server within Studio 5000 for communication with plc ControlLogix. The video: https://youtu.be/qcF4m7rPjkw However, according to a comment from the author of the video himself in my comment I can make such a connection through a Modbus device. How do I do this within ur5 and how can i access UR5 inside Studio 5000?
  20. I have a PLC ladder logic problem that I am stuck with and would like to know if there is a solution for it. PLC Ladder Logic Problem on PLC Fiddle: Automatic Window Blind There is a window blind that is controlled by using an opening and closing motor. There are 2 IR sensors that act as limit sensors to identify the boundaries of the opening and closing of the blind. The blind can either fully open or fully close. The blind is fully opened during day time and is fully closed during night time. We assume that the day time is for 12 hours and night time is for the other 12 hours. The PLC ladder logic must include at least a SENSOR, an ACTUATOR, a TIMER, and a COUNTER. You may use PLC Fiddle to draw the ladder logic: https://www.plcfiddle.com/ The process is as follows: 1. Assuming that the blind is now fully closed (during night), the night time 12-hour count down starts. The counter is done using a timer that counts 1 second, and after every second, the counter goes down starting from initial value of 12 (1 second represents 1 hour count down for simplicity). 2. When night time counter reaches 0, the counter resets back to 12 and stops, then the blind opening motor activates and keeps running until the blind edge reaches the opening limit sensor. 3. The opening motor then stops, and the day time 12-hour count down starts. The day time counter operates the same as the night time counter. 4. When day time counter reaches 0, the counter resets back to 12 and stops, then the blind closing motor activates and keeps running until the blind edge reaches the closing limit sensor. 5. The closing motor then stops, and the night time 12-hour count down restarts again. The whole process is repeated again. Please find attached below the rough sketch for the idea. Feel free to either sketch the ladder logic or use PLC Fiddle (link above). Thank you.
  21. Hello all,    I have 3 kinetix 5500 drives connected in series but some how the 3rd drive lost power. all the fuses in the cabinet look good. nothing else is tripped either.    any advice is appreciated.  thank you   
  22. Hi, I'm currently working as an intern, and my job is to transfer the program from a schneider twido twdlmda20rt to a mitsubishi fx5u-32mr/es. The thing is, i've been in trouble trying to understand and "translate" from one plc language to another certain things, like the %MW, %SW and blocks, so if any of You could give me some advisory I'd bee fully thankful (I can't upload all the pics, so theres's the link to the folder) https://inacapmailcl-my.sharepoint.com/personal/nicolas_gonzalez206_inacapmail_cl/_layouts/15/onedrive.aspx?id=%2Fpersonal%2Fnicolas%5Fgonzalez206%5Finacapmail%5Fcl%2FDocuments%2Fscript
  23. I'm looking for a serial device server, which will be a cheaper equivalent of moxa. Does anyone recommend anything?
  24. I hear a lot of people talking about the annoyance of price estimates (meaning they don't get a clear, transparent price from the beginning) and the costly engineering that seems to never end. Do you think that a step-by-step, clear process and course of action from A to Z would be beneficial for companies? And I'm not talking here about SCADA software, like Ignition. I'm talking about using Ignition to build and implement a fully working SCADA solution, customized to your company BUT you know exactly the price and the methods/processes that will be used (it's a replicable framework to get similar results for multiple companies - and the results would be a SCADA solution without the headaches of the unknown prices and engineering characteristics). Basically, a clear project-based approach rather than an hourly approach where things can get confusing.    Do you think the industrial space could use something like that?
  25. Good day everybody!    I am having issues troubleshooting a machine which is controlled by a VIPA PLC. I must admit that I am not very knowledgeable with this brand so I am a bit hesitant to touch anything. From the machine's supplier I got a .wld file which I could load into an SD card and load into the VIPA PLC itself through a Master Reset procedure. Still, our issue persists so I was wondering if I could somehow extract this .wld file into Speed7 Studio (or another program) to visualize it and try to troubleshoot the issue. Or in another case, if there was a way to directly read the currently loaded program from the PLC.    As I said, I had never worked with this brand before so I am being a little overly cautious with what I touch in this PLC.    Thanks for your help!
